Diathesis-Stress Model
The diathesis-stress model states that mental disorders arise from a combination of stressful life circumstances and genetic predisposition.
Understanding the diathesis-stress modelThe diathesis-stress model is based on the theory that mental and physical disorders develop in response to a genetic predisposition for that illness.
The model also believes that such an illness is more likely to develop after the individual has experienced a stressful or traumatic life event.
The diathesis-stress model touches on the subject of nature vs. nurture in psychology.
The subject, which was debated in ancient Rome and Greece, seeks to understand whether innate biological factors (nature) or social and situational factors (nurture) are the predominant cause of a disorder.
Rather than advocating one factor over another, however, the diathesis-stress model believes that a combination of the two is a more likely explanation.
To that end, the model posits that individuals with more predisposition to a disorder may require a less stressful event for it to manifest.
By the same token, the model has also been used to explain why some individuals who experience stressful life situations otherwise remain psychologically healthy.
The two components of the diathesis-stress modelLet’s take a more detailed look at the two components of diathesis and stress to better understand how they may interact to precipitate illness:
DiathesisDiathesis is an individual’s predisposition (or vulnerability) to a mental or physical disorder. It can be caused by:
Cognitive factors.Biology or genetics.Environmental stressors or traumatic experiences in childhood, andSituational factors, such as cohabiting with a parent who has a mental illness.While a child that lives with a mentally ill parent can eventually move out of home as an adult, most of these factors tend to remain with a person for their entire life and their negative effects are difficult to address completely.
Since diathesis is also a defacto measure of vulnerability, those who rate on the lower end of the scale will require a more stressful event to precipitate a disorder and vice versa.
StressStress may be caused by any number of events such as:
Divorce.Financial problems.Serious or chronic health issues.An upcoming test or exam.The death of a family member or friend, andThe COVID-19 pandemic.Irrespective of whether the stressor is short-term or chronic, it’s worth noting that diathesis can cause stress and the reverse is also true.
Protective factors in the diathesis-stress modelProtective factors explain why someone who experiences a lot of stress and is predisposed to illness can live their lives relatively unaffected.
The presence of protective factors has caused the model to be revised in recent years with some now calling it the “stress-vulnerability-protective factors model”. Examples of these factors include:
Professional counseling or therapy.Self-awareness.High emotional intelligence (EQ).Being a member of a support group.Stress management techniques, andUnderstanding of healthy coping mechanisms.Key takeaways:The diathesis-stress model states that mental disorders arise from a combination of stressful life circumstances and genetic predisposition.The diathesis-stress model is based on the interactions of diathesis (factors that predispose an individual to illness) and events that precipitate or induce the illness itself. Diathesis may cause stress and vice versa.Protective factors explain why someone who experiences stress and is predisposed to illness can live their lives relatively unaffected. Protective factors may take the form of self-awareness, professional help, support groups, and high emotional intelligence.Connected Business Frameworks

Venture Capital Advantages And Disadvantages


A venture capitalist generally invests in companies and startups which are still in a stage where their business model needs to be proved viable, or they need resources to scale up. Thus, those companies present high risks, but the potential for exponential growth. Therefore, venture capitalists look for startups that can bring a high ROI and high valuation multiples.
A glance at venture capital investingThe set of investments venture capitalists make; only a few will succeed. Therefore, they have to place more bets to make the system work in their favor.
In the end, the venture capitalist makes money (the so-called exit) by either reselling the stake in the company at a much larger valuation or with the IPO of the company they invested in.
When that happens, venture capitalists make substantial returns for their partners. Indeed, the venture capital firm is usually comprised by a group of partners which raised capital from another group of limited partners to invest for them.
The limited partners (or LPs) can be either large institutions or wealthy individuals looking for high returns.
Usually, venture capital firms invest in growth potential. Therefore, when a startup receives venture capital money, the venture capital firm – usually – expects aggressive growth.
Before we get to the advantage and disadvantages of taking venture capital money, let’s first understand the explicit and hidden incentives that drive venture capital firms. Indeed, at the end, taking venture capital money is mostly about interests alignment.
And if those interests do not converge, that is when probably it might be not a good idea to take that money.
Understand the venture capital incentivesTo understand how venture capital works, we need to look at the two resources that they allocate:
capital;and moneyTime, because VCs funds, compared to other models, where financial resources are endowed, do contribute to the growth of the firm they invest in. This contribution can come in several ways, from assistance in hiring to providing guidance, or also having a VC on the board.
On the other hand, VCs provide capital for funding the scale of those startups.
Why is it important to understand the two essential resources? Well, while capital might be a relatively scalable resource, assuming VCs can bring in continuously limited partners.
Time is not. Indeed, VCs usually run out of capacity in managing a certain number of investments as those investments need to be also managed and supported.
And in general, VCs look for a return anywhere between 3-10 years, depending on the market condition, startup growth and more.
Which means they also look for 10-30x ROI in a 5-10 year timeframe.
Therefore, a few aspects we can highlight so far:
venture capital have limited time resources to allocate due to the fact they can only manage a certain number of investments (as they provide several forms of support to startups);they look for extremely high returns (10-30x in the lifespan of the investment);those returns can happen anywhere between 3-10 years depending on several conditions (this means in this period VCs will ask for aggressive growth)Let’s look now at the advantages and disadvantages of getting VCs’ money.
Advantages of VC moneySome of the key advantages can be summarized in a few key points:
Guidance and expertise: usually VCs don’t bring just cash on the table but also the expertise of the team and partners part of the fund, which is one of the primary advantages of getting VCs’ money.Rapid Growth: if you’re looking for rapid growth, VCs will look for the same thing. Thus, you’ll both be aligned in terms of objective, which makes it easier to make this sort of agreement work.Connections: VCs will introduce you to the right people to unlock growth potential, which is another undeniable advantage.Hiring: the VC investing in your company can also help you find the right people to form your team and scale.Additional support: in some cases, VCs support can also come in other areas that are important to grow smoothly, which include legal, tax, and accounting matters.For all these reasons, VC money makes sense. Let’s see when it doesn’t.
Disadvantages of VC moneyThere are two significant disadvantages in taking VC money:
Loss of control and ownership: this is by far the most significant disadvantage as if you let VC in it means you need to be ready to give up some or a good part of the control. Therefore, you won’t be the only one in charge of the company’s vision and mission, but you’ll need to share that with the VC.While it is legitimate for VC to ask a high ROI for a risky startup which business model still needs to be proved viable. A very High ROI and an excessive push on growth might break things up. Remember that, companies, like products, might have a lifecycle and forcing too much on growth might well make the company implode.When does it make sense to take venture capital money?In a post entitled “The only thing that matters,” venture capitalist Marc Andreessen explained:
The only thing that matters is getting to product/market fit.
Product/market fit means being in a good market with a product that can satisfy that market.
How do you assess whether you passed through this product/market fit stage?
Marc Andreessen explained:
You can always feel when product/market fit isn’t happening.The customers aren’t quite getting value out of the product, word of mouth isn’t spreading, usage isn’t growing that fast, press reviews are kind of “blah”, the sales cycle takes too long, and lots of deals never close.
Therefore, there is no single way to measure that, but as Andreessen emphasized:
And you can always feel product/market fit when it’s happening.The customers are buying the product just as fast as you can make it — or usage is growing just as fast as you can add more servers. Money from customers is piling up in your company checking account. You’re hiring sales and customer support staff as fast as you can. Reporters are calling because they’ve heard about your hot new thing and they want to talk to you about it. You start getting entrepreneur of the year awards from Harvard Business School. Investment bankers are staking out your house. You could eat free for a year at Buck’s.
And he highlighted something that would stick as a paradigm in the startup world for years to come:
Lots of startups fail before product/market fit ever happens.
On FourWeekMBA, I interviewed Ash Maurya, author of Running Lean and Scaling Lean and creator of the Lean Canvas.
As he explained to me:
This is (when to take VC money), of course, going to be a function of the kind of business model and product that you have. If you can bootstrap, if you can go all the way to product market fit and then raise money, you maintain the most control in your company. You have a lot of say in where the company goes from that point on.
And he continued:
In an ideal world, and it’s not just me, even the venture capitals and other angel investors will give you the same advice. The best ideal time to raise your big round of funding would be as you cross product-market fit.
Once you have product-market fit, some success is guaranteed. The question is how big can it get?
The other thing that’s also going in your favor then is that your goal, you being the entrepreneur or innovator, your goal and the investor’s goals are completely aligned. It’s all about growth.
You have figured out the product, you have figured out the customer, now it’s really engines of growth.
Source: blog.leanstack.com
Thus, if you were in the condition to bootstrap – grow with your resources, or with a profitable business model – your company is in a perfect place to be.
You can decide whether to move to the next stage (scale), thus take VC money. Or keep growing organically.
And he also highlighted:
What questions to ask before taking venture capital money?
If you were doing something that required capital investment upfront, this is where VC makes sense, but there is now, increasingly so, a very mature market of other investors that play in that space.
Those would be super angels or angel investors that understand that you still haven’t reached product-market fit and you are going to be learning and pivoting and course correcting, and they tend to be more patient for those types of things.
Therefore before taking VC money, I would ask the following questions:
can I validate the idea without external resources?Is the product technically complex that it requires additional resources to develop?Do I need money to scale?Am I ready to give up part of the control of my business?In short, if you are a control freak, and you want to keep your vision of the company intact, VC money might not be the best option. If you’re willing to give up some control in exchange for money and expertise that might make sense.
In other cases, if you managed to bootstrap your way to product/market fit you might be in a good position as VC will want you. Thus, you will be able to negotiate better deals.
In the case in which you need a long term perspective to grow your business and still be in charge of angel investing or “super angels” might be a better option.
In all the other cases, bootstrapping is the way to go!

What Is the SERVQUAL Model? SERVQUAL Model In A Nutshell


The SERVQUAL model was created by researchers A. Parasuraman, Valarie Zeithaml, and Leonard L. Berry in 1985 to measure and drive quality in the service and retail sector. The SERVQUAL model is a framework for measuring service quality and customer satisfaction through five dimensions: reliability, responsiveness, assurance, tangibles, and empathy.
Understanding the SERVQUAL modelIrrespective of the industry, however, most businesses need to provide some degree of customer service. This requires an understanding of how the customer’s mind works and what drives their decisions or actions.
The SERVQUAL model helps bridge the gap in perception between what the company believes it is delivering to customers and what those customers expect, want, or need during customer service.
Although developed before the digital age, the SERVQUAL model is still relevant today. With customers now using the internet to share their thoughts with a vast and captive audience, perception management has never been more important.
The five dimensions of service qualityThe SERVQUAL model considers five dimensions customers use to evaluate the quality of service they receive from a business.
These dimensions include:
Reliability – how consistently does the organization deliver a product or service on time, as described, and without error? For the customer, reliability means the organization respects commitments and honors promises.Responsiveness – how quickly can the organization respond to customer needs? Despite the negative perception it creates, some businesses ignore or evade customer service requests for no apparent reason.Assurance – does the organization inspire trust and confidence in customers with professional service, great communication skills, technical knowledge, and the right attitude?Tangibles – or the visual aesthetic of a company derived from its logo, physical store, or the look and feel of its website. Tangibles also encompass equipment, with hand sanitizing and contactless payment devices influencing the consumers of today. Furthermore, the fourth dimension also includes the physical appearance of customer service staff. How well are they dressed? Do they practice good personal hygiene? Empathy – or the ability for employees to show genuine care and concern during customer service. In other words, are those tasked with providing customer service friendly and approachable? Do they actively listen to consumer needs? Indeed, are they sensitive to consumer needs?The five gaps of service quality in the SERVQUAL modelThe SERVQUAL model defines five scenarios where businesses often fall short of customer expectations.
As mentioned in the introduction, gaps emerge when there is a discrepancy between the needs or wants of the consumer and the services the organization provides.
Each of the five gaps is summarised below:
Knowledge gap – a knowledge gap occurs when an organization has not done its due diligence on the target audience. Whether through insufficient or careless research, knowledge gaps reflect a lack of market understanding.Policy gap – these gaps occur because of a conflict between what the customer wants and what the organization provides. Policy gaps may be caused by an insufficient commitment to service quality, lack of task standardization, or inadequately described service levels.Delivery gap – or dissimilarity between the standards of customer service set out in policies and the actual delivery standard. This is a common problem in many businesses and may be the result of poor technology, poor management, low employee engagement, and role ambiguity or conflict.Communication gap – this gap describes a difference between what the company chooses to advertise about a product and what the customer actually receives. Communication gaps occur because of over-commitment or a lack of cohesion between the advertising and product development departments.Customer gap – simply, the difference between customer expectations and the experience created for them by the business. Customer gaps can be explained by revisiting the five service quality dimensions of reliability, responsiveness, assurance, tangibles, and empathy.Key takeaways:The SERVQUAL model is a framework for measuring service quality and customer satisfaction. It was created by researchers in 1985 to measure and drive quality in the service and retail sectorThe SERVQUAL model assesses five dimensions of service quality: reliability, responsiveness, assurance, tangibles, and empathy.The SERVQUAL model also defines five knowledge gaps that help explain how and why a business falls short of customer expectations. These include gaps in knowledge, policy, delivery, communication, and general customer experience.Related Business Concepts

History of AWS
Not all cloud businesses are born equal.
Some context below for Q2 of 2022:
– Amazon AWS = $19.7B
– Microsoft Intelligent Cloud = $20.9B (Note: this is a larger segment, comprising Azure + other cloud services).
– Google Cloud = $6.27B
As of now, Microsoft’s Azure is a real threat to AWS.
Google Cloud runs at negative margins.
The Google cloud segment lost $858 million in Q2.
Why does the cloud matter so much?
Well, the whole AI ecosystem is getting built on top of it.
In short, the cloud infrastructure is the basis for AI companies to develop, thus creating the next digital industrial revolution.
How come prominent players like Microsoft and Google couldn’t compete with AWS for years?
Two things:
– Early timing.
– Bezos played a trick on his competitors.
When Amazon officially launched Amazon AWS in 2006, none imagined what a cash machine it was and what it would become.
And Jeff Bezos was pretty smart about it.
What was the trap he employed?
Indeed, when AWS officially launched, it was priced as a utility.
Bezos wanted to avoid “Steve Jobs’ mistake” of pricing the iPhone at such high margins to quickly attract competition.
Instead, Bezos initially made AWS a low-margin business, and over time, it became a highly profitable segment.
AWS rolled out its first mass-market product, Simple Storage Service, or S3, on March 14, 2006.
That is the official date of birth of AWS!
However, AWS was born in the early 2000s. As Amazon went through the dot-com bubble, the company had to redefine its business model.
Jeff Bezos wanted to cash in the Internet revolution by placing bets everywhere. Yet by the early 2000s, many of these bets had turned to zero.
The primary example was pets-com, which went bust in November 2000.
Amazon had to refocus. Get back on strengthening its e-commerce infrastructure and, most of all, change the paradigm. Move from e-commerce to platform.
In short, to quickly expand the selection of goods while keeping prices low, they had to host as many third-party stores on Amazon.
That was an opportunity to fix the jumbled mess which had become the underlying Amazon infrastructure.
Thus, AWS also came about as a side effect of Amazon’s change in paradigm (from e-commerce to platform).
For a period in the 2010s, AWS has powered the whole Web2 startup ecosystem (Airbnb, Instagram, Netflix, Pinterest, Slack, and many more).
And a crucial personal detail, AWS was led by Andy Jassy since 2003. Eventually, Jassy took the place of Bezos as CEO of Amazon.
So you get what a revolution AWS was for Amazon from a business standpoint!
The low-margin strategy worked. Only in 2008 did Google realize the threat of AWS launching its own Google Cloud Platform.
And Microsoft took even longer, launching its Azure in 2010.
That gave AWS an incredible bandwidth to organically grow AWS into the most powerful tech company these days.
Three takes from this story:
– AWS was born as side effect of a paradigm shift: paradigm shifts can be extremely powerful when a breakthrough moment comes. And the dot-com bubble, a survive-or-die moment, really defined Amazon for the next twenty-five years. Also, from this paradigm shift, as an effect, of making difficult decisions, you might stumble upon gild mines! That is how Amazon stumbled upon AWS.
– The physical platform becomes the basis for building an incredible service business: when a company manages to build the next physical platform, initially, margins do not matter. indeed, in the long run, the company owning the physical platform will be able to build a service business on top of it with incredible margins. Often, the service side of the business will serve as the profit and cash flow center to keep subsidizing the physical product for a larger and larger group of people.
– Hide the margins: as the story shows, everyone wants to be in a high-margin business. And a few want to risk their margins. That is why the fact that Amazon hid under its hood the margins and profits of AWS helped it to become the tech giant we know today. Only two years later, from the first AWS official launch, Google came out with a cloud service, and only by 2010 Microsoft did do the same.

What Is Evidence-based Management? Evidence-based Management In A Nutshell


Evidence-based management is a decision-making approach that uses critical thinking and the best available evidence. Evidence-based management is an approach that considers multiple sources of scientific evidence and empirical data as means of attaining knowledge and making decisions.
Understanding evidence-based managementThis means scientific literature is used to answer questions, guide strategy decisions, and formulate long-term plans. Evidence-based management is an emerging movement that forms part of the larger transition to evidence-based practices.
The transition began to gather momentum after the introduction of evidence-based medicine in 1992, with the approach quickly spreading to education, law, public policy, architecture, and many other fields.
Ultimately, the goal of an evidence-based approach is to encourage professionals to give more credence to evidence while making decisions. The approach seeks to replace the ineffective practices that base decision-making on tradition, intuition, and personal experience.
The key components of evidence-based managementIn a nutshell, evidence-based management is based on three key components:
The best available evidence – this means evaluating multiple sources of scientific evidence and empirical results to discover new interventions and strategies. In addition to scientific research, evidence may take the form of organizational data, professional expertise, or stakeholder values and concerns.Systematic decision-making – decisions are made by considering the published literature, critically appraising evidence, and crafting a strategy underpinned by science. Mental biases, prejudices, or lazy thinking must be reduced or eliminated.Re-evaluating and adapting – all decisions must be critically examined and evaluated using the scientific method. Consistently evaluating the original hypothesis is the only way to determine whether the strategy or decision had its intended effect.Incorporating evidence-based managementTo deliver better outcomes in an organizational context, the Chartered Institute of Personnel and Development and the Center for Evidence-Based Management developed six steps:
Asking – the process begins by taking a practical issue or problem and turning it into an answerable question.Acquiring – in the second step, decision-makers systematically search for and retrieve evidence.Appraising – the evidence is then critically appraised for trustworthiness, quality, and relevance. Where and how was the evidence gathered? Could it be biased? Is it the best available evidence? Is there enough evidence to reach a conclusion?Aggregating – in the fourth step, the evidence is combined and weighted according to relevance or importance.Applying – the most important evidence is then incorporated into decision-making.Assessing – in the assessment stage, the outcome of the decision must be evaluated regularly. Does the evidence-based decision support the answerable question or hypothesis? Key takeaways:Evidence-based management is a decision-making approach that uses critical thinking and the best available evidence. The approach seeks to replace decision-making based on personal experience, intuition, or tradition.Evidence-based management is based on three key components: the best available evidence, systematic decision-making, and re-evaluating and adapting. In addition to scientific research, the best available evidence may also be related to stakeholder values and concerns, internal data, and professional expertise.Evidence-based management delivers better organizational outcomes in six steps: asking, acquiring, appraising, aggregating, applying, and assessing. Collectively, the steps help decision-makers answer questions and test hypotheses. Related Goal-Setting & Growth Frameworks

What is market depth?
Market depth shows the various buy and sell orders that have been placed on the market for a particular security. It is normally arranged in a table of live bid-ask prices with the total number of buyers and volume listed for each price.
Understanding market depthMarket depth is an indicator of volume and provides a real-time snapshot of buy and sell orders for a particular security.
Both investors and traders use market depth to analyze the various prices and volumes that accumulate on either side of the bid and ask price.
Relatively liquid securities will show good market depth, which means large orders will not impact the price significantly.
Relatively illiquid securities have poor market depth and their prices are more affected by large orders.
Market depth is particularly important for traders because it enables them to determine short-term market sentiment.
When sellers outnumber buyers, for example, there is weakness in the price of the security. When the reverse is true, the price of the security is likely to increase.
Information from market depth can also be used to:
Determine where one’s order sits in the queue of buyers or sellers and how long they may have to wait before it is filled. An order where the investor sets the specific buy or sell price is called a limit order.Analyze the amount of seller volume to determine whether a market order is appropriate or indeed cost-effective.Determine the point at which the majority of buyer and seller activity is taking place. This can be used to place an order at the head of the queue to ensure it is filled.Factors that influence market depthHere are a few factors that influence market depth:
Tick size – the minimum price increment at which trades may be executed. In the United States, the tick size is one-hundredth of a dollar, or $0.01. This was changed in 2001 from one-sixteenth of a dollar to improve market depth.Market transparency – while bid/ask prices are available most of the time, information about the size of an order or one that is pending is sometimes hidden from view. Less transparent market depth information can cause some investors and traders to refrain from participating.Available leverage – minimum margin requirements set by regulatory bodies stabilize the marketplace, but they also decrease market depth. In other words, those willing to take on more leverage cannot do so without obtaining more capital.Trade restrictions – various restrictions prevent market participants from adding depth when they are interested in doing so. Examples include options position and futures contract limits and the uptick rule, which states that short telling is only permitted when a security is on an uptick.Key takeaways:Market depth is an indicator of volume and provides a real-time snapshot of buy and sell orders for a particular security.Market depth is particularly important for traders because it enables them to determine short-term market sentiment. The ratio of buyers and sellers and their respective volumes may clarify whether there is strength or weakness in the price of the security.Factors that influence market depth include tick size, market information transparency, limits imposed on available leverage, and trade restrictions.Main Resources

Responsive Search Ads
Responsive search ads (RSAs) are those that can be customized based on the end user’s search query with multiple headlines and descriptions.
Understanding responsive search adsIndividuals and businesses can use responsive search ads to promote their products and services on the Google Network.
Introduced in 2018, some of the primary features of responsive search ads include:
The ability to define two or more descriptions and three or more headlines that are automatically tested to determine which combination works best. Customized URLs which can be appended to the end of a landing page address, andThe ability to pin desirable headlines or descriptions such that they always appear in the advertisement.Starting June 30, 2022, responsive search ads became the only search ad type that could be created or edited in a search campaign. Although this move was announced with plenty of warning, it nonetheless marked a significant shift in the way PPC marketers needed to approach their advertising efforts.
Indeed, while the prior system of expanded text ads had its shortfalls, it was also reliable, comfortable, and offered businesses more control over what ads were shown and at what time.
How do responsive search ads work?Advertisers can select up to 15 headlines and 4 descriptions for a single search ad which translates to a maximum of 43,680 ad permutations. These are then processed by Google’s machine learning algorithm to increase engagement and click-through rate.
Ad performance may be sub-optimal to start with as the algorithm learns the most effective headline-description combinations. Over time, however, it serves optimized ads based on a user’s search behavior, device preferences, and various other signals.
As a result, businesses must resist the urge to pull under-performing ads before the algorithm has had a chance to determine what works best. It’s also worth noting that the technology is not a panacea that will deliver guaranteed results. These algorithms can only use the information a business has provided them with so it’s important that the best converting words and phrases are identified ahead of time.
Responsive search ad best practicesGoogle notes that responsive search ads have a CTR that exceeds those seen in standard search ads by 5-15%. Here are some of the ways a business can maximize its ROI from the new system:
Don’t settle for the bare minimum – while ads must have a minimum of three headlines and two descriptions, it would be foolish not to utilize the system to its maximum capacity and test thousands of ad permutations.Use the pin functionality wisely – if there is information that absolutely must be shown in an ad like a brand message or disclaimer, it can be pinned to the headline or description. However, excessive pinning can limit the effectiveness of the machine learning algorithm. When two headlines are pinned, for example, the number of possible permutations is reduced by 99.5%.Consider ad groups – since Google already tests various versions of the responsive search ad, there is no need for the business to include multiple ads in the same ad group. Multiple ads has the reverse effect of slowing down the optimization process.Key takeaways:Responsive search ads (RSAs) are those that can be customized based on the end user’s search query with multiple headlines and descriptions.Google’s machine learning algorithm can analyze a maximum of 43,680 ad variations to increase engagement and click-through rate. This process can take time, so it’s important for businesses not to pull their ads early if the results are sub-optimal.To maximize the benefits of responsive search ads over standard search ads, businesses should use their full allocation of permutations, use the pin functionality wisely, and use one ad per ad group.More Resources

Is Netflix Profitable? Netflix Profitability 2014-2021


Netflix is a profitable company, which net profits were $5.1 billion in 2021. Growing from $2.7 billion in 2020. The company runs a negative cash flow business model, where it anticipates the costs of content development and licensing through the platform. Those costs get amortized over the years, as subscribers stick to the platform. This is the main weakness of Netflix’s business model.
What drove Netflix’s profitability?In 2021 revenues drove profitability.

However, as of 2022, for the first time in years, Netflix’s subscriber base has slowed down, thus steering the company toward restructuring its whole strategy for the next decade, and revamping the Netflix Business Model.
Netflix old plans in euros
Netflix new plans in euros
As we’ll see Netflix has been increasing its content expenses as it continues to acquire, license, and produce content (Netflix originals).
Netflix offers three main types of streaming membership plans:
BasicStandardPremiumWhy Netflix is investing massively in content
While Netflix has a positive income and shows growing profits.
The company also used a substantial amount of cash for its operating activities.
It’s important to understand the unit economics of the Netflix business model. The company has to pay in advance for the right to stream content, or at least have content ready to be streamed on its platform.
Indeed, it’s critical for Netflix to show its members that it has a library of content always available, and it is also critical for Netflix to make an upfront investment in original content.
To understand why we need to look at the Netflix distribution strategy.
Understanding the Netflix distribution strategyA distribution strategy starts with a product. Without a product, there is no distribution. For how trivial that might sound if we go back a few years, Netflix didn’t have a product of its own.
Instead, the company assembled the content to stream on its platform for its members.
While this strategy worked pretty well over the years.
As Netflix scaled up and it became a threat to the same platforms licensing that content to it. Netflix realized it needed to start producing its own content, what the company calls Netflix Originals.

If you have a strong distribution platform but you don’t have a product you make, there are several long-term risks:
You’re subject to the provider of content changing agreements, pricing, and distribution.Your brand won’t be recognized.You are not free to distribute that content as you wish as the licensing agreements might have intrinsic limitations.When you do understand that, you can appreciate why Netflix is burning so much cash to produce its own content.
And again those higher expenses were primarily driven by increased headcount to support growing streaming services, the international expansion, and the increased content production activities.
Why content is so expensive?
Original content is extremely expensive.
A show like Chris Rock’s stand-up series for Netflix costs $20 million per episode. A series like Orange Is the New Black cost as much as $50 million per season.
If you add those numbers up for all the original series, documentaries and else that make-up billion of dollars in investments.
That is why Netflix balance sheet in the coming years will be dominated by an item called “screaming content obligations” which consists of almost $20 billion, and that the company will have to pay in about five years.

Is Uber Profitable? Uber Profitability 2016-2021


Uber made over $17.45 billion in revenues in 2021, and its losses were $496 million, thus in 2021, Uber was not profitable. In 2021, Uber generated over $17.4 billion in revenues, mostly coming from mobility ($6.95B or 39.8% of its total revenues) and delivery with Uber Eats ($8.36B or 47.9% of its total revenues).
Understanding Uber financialsUber made over $11 billion in dollars in revenues in 2018, and its profits were $987 million. In 2017, the company earned $7.9 billion in revenues, and its net losses were over $4 billion. And in 2016, Uber made $3.8 billion in revenues, and its net losses were over 370 million dollars.
It’s essential to notice that the profitability in 2016 was positively affected by the sales of Uber China for $2.9 billion. And in 2018 it was positively impacted by divestitures in Russian operations and gains on investments for Chinese’ Uber, called Didi.

Sale of Uber China
Sales of Uber China, which would go to the Chinese startup, Didi. Source: Uber Financial Statements.
As pointed out in Uber financial statements:
On August 1, 2016, the Company sold its majority-owned subsidiary, Uber China, Ltd. (“Uber China”) to Xiaoju Kuaizhi, Inc. (“Didi”) for an equity stake in Didi, valued at the time at approximately $6.0 billion. The financial results of Uber China’s operations are presented as discontinued operations in the consolidated statements of operations and, as such, have been excluded from continuing operations for all periods presented. Refer to Note 15—Discontinued Operations for further information. During the year ended December 31, 2018, the Company completed the disposition of the Uber Russia and the Commonwealth of Independent States (“Uber Russia/CIS”) operations and the sale of the Southeast Asia operations. Refer to Note 19—Divestitures for further information. These 2018 divestitures did not represent a strategic shift that had a major effect on the Company’s operations and financial results, and therefore are not presented as discontinued operations.
Pretty much Uber sold to Didi, but then it acquired a stake into the company by 2017:
From the schedule above, you can see the several investments Uber made throughout the years, also based on dismissions, sales, and joint ventures.
Dismission of Russia/CIS operations with the creation of the Yandex joint ventureAs pointed out on Uber financial statements:
Uber operations in 2018In July 2017, a wholly-owned subsidiary of the Company agreed to contribute the net assets of its Uber Russia/CIS operations into a newly formed private limited liability company, MLU B.V., with Yandex and the Company receiving ownership interests in MLU B.V. As a result of this transaction, the Company determined that the contributed assets and liabilities were disposed of and met the held for sale requirement as of December 31, 2017. The Company performed an evaluation to determine if the sale constituted discontinued operations and concluded that the sale did not represent a major strategic shift, primarily because the Uber Russia/CIS operations did not materially affect consolidated assets, revenue or loss from operations of the Company. In addition, the Company determined the sale constituted the sale of a business in accordance with ASC 805. The carrying value of Uber Russia/CIS’s total assets and liabilities were $20 million and $15 million as of December 31, 2017, respectively. The transaction received approval from the necessary regulatory agencies in the fourth quarter of 2017 and closed on February 7, 2018.

Gain and divestitures are coming from dismissed, sold, and reorganized operations.
Gain on divestitures increased by $3.2 billion from 2017 to 2018. This increase was due to gains on the divestitures of our Russia/CIS and Southeast Asia operations.
Unrealized gain on investments increased by $2.0 billion from 2017 to 2018. This increase was primarily due to a gain from a fair value adjustment of our Didi investment.

Simon’s Satisficing Strategy In A Nutshell


Simon’s satisficing strategy is a decision-making technique where the individual considers various solutions until they find an acceptable option. Satisficing is a portmanteau combining sufficing and satisfying and was created by psychologist Herbert A. Simon. He argued that many individuals make decisions with a satisfactory (and not optimal) solution. Satisfactory decisions are preferred because they achieve an acceptable result and avoid the resource-intensive search for something more optimal.
Understanding Simon’s satisficing strategySimon is also the father of bounded rationality.
Indeed, humans lack the cognitive resources to make optimal decisions. We have little understanding of outcome probabilities and can rarely evaluate relevant outcomes with sufficient precision. Furthermore, our memories tend to be unreliable.
Given these limitations, a more realistic approach involves logical and reasoned decision making. Simon called this process “bounded rationality”. Here, satisficing individuals make decisions that are based on certain, non-exhaustive criteria.
Satisficing versus maximizingSatisficing is not exclusively driven by cognitive limitations. It also seeks to maximize utility, or the extent to which a task or choice is pleasant or desirable.
For many years, behavioral economists assumed that task desirability was linked to how much information the decision-maker had at their disposal.
But this is untrue. To prove this, consider the key differences between a satisficer and a maximizer:
The satisficer is not attached to the very best outcome. As a result, they experience less regret and higher self-esteem than their maximizing counterparts – who tend to be outcome-dependent perfectionists.The satisficer can move on after deciding, while the maximizer needlessly expends more time and energy ruminating.The satisficer does not obsess over other options and is happier for it. Conversely, the maximizer makes decisions based on external comparisons and not on their own needs or pleasure. This tends to make them unhappier.Examples of Simon’s satisficing strategyConsider the consumer who has a leaking pipe in their basement on a weekend. The best solution to this problem is replacing the pipe, but this entails finding a suitable plumber and is an expensive fix. Instead, the consumer chooses to stem the leak with a temporary sealant. While the sealant is by no means a permanent fix, it is satisfactory enough to stem the leak and saves time, money, and energy.
Satisficing has implications for copywriting and web design too. Visitors will tend not to stay on a company site for long unless there are obvious and satisfactory solutions to their problems.
The strategy can also be seen in consumer psychology. When choosing a product such as a pipe sealant, the consumer is looking for the simplest, most readily available option. While more effective solutions exist, they do not come into consideration.
For example, an office worker might purchase a single piece of accounting software despite there being more benefit in buying the whole suite. A fitness fanatic may purchase a low-quality pair of earphones to use while running, despite several competitor products offering better sound rendition.
Key takeawaysSimon’s satisficing strategy is a form of decision making that advocates satisfactory and not optimal solutions.Simon’s satisficing strategy avoids cognitive overload in the often fruitless search for optimal outcomes. These outcomes result in needless expenditure of time, energy, or money.Simon’s satisficing strategy has applications in consumer psychology and user design. Consumers who adopt the strategy tend to be happier and have higher self-esteem than those who opt to maximize the outcomes of decision making.As highlighted by German psychologist Gerd Gigerenzer in the paper “Heuristic Decision Making,” the term heuristic is of Greek origin, meaning “serving to find out or discover.” More precisely, a heuristic is a fast and accurate way to make decisions in the real world, which is driven by uncertainty.
What is a Heuristic? Beyond biases and the prevailing narrowed vision of the mindIn a 1996 paper entitled “Reasoning the Fast and Frugal Way: Models of Bounded Rationality” psychologists Gerd Gigerenzer and Daniel G. Goldstein highlighted:
Humans and animals make inferences about the world under limited time and knowledge. In contrast, many models of rational inference treat the mind as a Laplacean Demon, equipped with unlimited time, knowledge, and computational might.
This is a very important concept to start with. Where modern psychologists and theorists of mind manufacture experiments in the lab, those experiments are tied to specific scenarios, that are hardly replicable in the real world.
Why is that? It all starts with a narrow theory of mind.
A narrow definition of rationalityExperiments are manufactured and often based on assumptions around how our minds work. For instance, if a psychologist will label rationality as the ability to optimize during a decision-making process (just like a machine would do) this requires the mind to gather all the possible information to come to a logical decision.
However, in the real world, decisions are made with incomplete information, a high degree of uncertainty and little to no understanding of what’s coming next. Therefore, when the psychologist mutters about the inability of the human brain to understand statistics or logic. In the real world, that means survival.
If surviving means losing some efficiency or avoiding optimization to prevent massive failure, our mind is working as it should.
Risk vs. UncertaintyAnother component that the conventional or prevailing school of thought is the lack of understanding of the domain in which the human mind is operating. That’s a key point to understand the difference between risk and uncertainty.
Risk is computableRisk is a concept that analysts love. Why? It’s something that can be modeled. Thus, circumscribed to scenarios that have definite rules, like games. You often see in business books how game theory helped businessmen to be successful.
But that is a story crafted in hindsight. Game theory or your skills as a chess player might help you (in impressing others) in normal circumstances (assuming those exist) but they won’t help you much in the real world. Unless you have an alternative toolbox made of heuristics.
Uncertainty is not computableWhen financial analysts evaluate risks they fall into the trap of thinking that we can understand the real world by modeling it. The modern approaches to entrepreneurship try to bring this same logic to the business world, with nefast consequences.
When there is a high variability of outcomes, it’s impossible to model the risk. If at all you need a simple set of rules of thumb to avoid the worst-case scenario because if that materializes that will be no risk-model that will help with that.
Indeed the consequences of an uncertain scenario might be too bad for you to actually even see its outcome because survival is at stake.
Unmodeling the real worldWhen psychological experiments are made in the lab, often times the psychologist starts with a preconceived idea of the human mind and she works her way back to prove it with an experiment.
When that happens experiments are “manufactured” (in many cases unconsciously) to produce a certain result (in short, biases are more a domain applicable to psychologists than of laypeople dealing with real-world uncertainty).
This has come up recently with what is called a Replication Crisis, which as highlighted on Wikipedia:
The replication crisis (or replicability crisis or reproducibility crisis) is, as of 2019, an ongoing methodological crisis in which it has been found that many scientific studies are difficult or impossible to replicate or reproduce. The replication crisis affects the social sciences and medicine most severely.
Part of this trend is in the use of statistical tools that are not proper for real-world analyses, and the fact that research sometimes turns into an attention-driven activity. As pointed out by Noah Smith in Bloombergs’ “Why ‘Statistical Significance’ Is Often Insignificant:”
In psychology, in medicine, and in some fields of economics, large and systematic searches are discovering that many findings in the literature are spurious. John Ioannidis, professor of medicine and health research at Stanford University, goes so far as to say that “most published research findings are false,” including those in economics. The tendency research journals have of publishing anything with p-values lower than 5 percent — the arbitrary value referred to as “statistical significance” — is widely suspected as a culprit.
To be sure, this is not to say those experiments aren’t valid. Worse than that, in some instances, they carry from the beginning assumptions about the psyche of the subjects that are biased themselves.
In short, the biases that we all talk about nowadays, especially in the business world, in reality, might easily be explained with a theory of mind that goes beyond the conventional definition of rationality.
This definition starts by thinking of our mind as an easily tricked machine, that due to its survival mechanisms isn’t well-adapted anymore to modern times. Thus, it can easily fall prey to dozens if not hundreds of biases that affect our daily lives.
That is we see anywhere today in business publications massive lists of cognitive biases that make us more “aware.”
Heuristics: dirt and quick? Not really!As highlighted in “Heuristic Decision Making:”
The goal of making judgments more accurately by ignoring information is new. It goes beyond the classical assumption that a heuristic trades off some accuracy for less effort.
The main perspective for which heuristics have been studied and communicated to a mass business audience is through the fact that by definition a heuristic is quick and dirty. In short, our error-prone mind generates biases because we use heuristics that made us sacrifice efficiency for speed in the face of a sort la lazy mechanism of the mind.
According to this view, the mind might ignore important information in an efficiency-driven way, almost like it was optimizing for computing power.
In reality, the mind might have learned that ignoring useless information is a more effective survival mechanism in that specific context. Therefore, focusing on one key data point is way more reliable than taking more information. This completely changes the paradigm.
Where a lazy-driven mind avoids too much information because it’s not computably able to process it (thus sacrificing efficiency for speed almost like it was a computer). In a new paradigm, where heuristics and rules of thumbs become central as a necessary filtering mechanism of the mind that learns ho to ignore useless and irrelevant information.
In short, what matters is the outcome of the action, not the process neither the motivation that drives the process.
Conflict of interests, marketing, and manipulationNew media have enabled companies to communicate at large scale. When this communication is done right we can call it marketing. When that’s done wrong we can call it a conflict of interest or at worst manipulation.
Thus, many of what we call biases are also the consequence of the way the message gets framed to us. In short, it’s like playing a game where one player has to trick the other. As the other player learns the tricks of the first player, new strategies need to be found.
One there is a gap between the trickster and the tricked a bias might emerge as a better ability of the trickster.
Blind faith in technologyWhile planning a trip back to the city I live in, I was thinking to postpone the trip due to bad weather. While consulting my GPS which optimizes for shorter routes (not certainly for the beauty of the landscape or chances of survival) I risked to get to the end of the trip underwater.
In short, the GPS was giving me the time to destination with a bit of delay but without necessarily mentioning that I was getting there by risking to be flooded!
This blind faith in technology isn’t due to our inability to deal with it. Rather with the way these technologies are framed. When technology is built to optimize, and when it is marketed so that you believe that optimization is what matters in any context (optimization works in narrow ordinary situations) you end up relying too much on it.
The central problem with a two-system thinking modelTheories proposed by psychologists like Kahneman and Tversky have become central in the business world. The book Thinking, Fast And Slow has become a business bible and indeed that is a great read.
Yet the assumptions underlying these theories stand on a hypothetical optimization process humans should follow when making a decision. As highlighted in the paper “Heuristic Decision Making:”
As Kahneman (2003) explained in his Nobel Memorial Lecture: “Our research attempted to obtain a map of bounded rationality, by exploring the systematic biases that separate the beliefs that people have and the choices they make from the optimal beliefs and choices assumed in rational-agent models”
This view might start with a wrong definition and interpretation of bounded rationality formulated by Simon. Bounded rationality is not about systematic biases, it’s about decision-making in the real world, which is unpredictable.
Fast, frugal, yet accurateAnother key concept to internalize to deeply understand this alternative view of bounded rationality is the concept of ecological rationality. Ecological rationality looks for strategies that are better suited for a specific environment and context.
The key point here is that there is no best strategy, or optimization strategy because that would not be possible in a large world made of uncertainty.
Therefore, the rules of thumb we might be able to use for each circumstance will help us take advantage of the structure of the environment we operate within.
Thus in this sort of decision-making process, it is like we do create a small world but highly adapted to context and circumstance, which is the opposite of what classic theories of rationality do, assuming that our mind works in a vacuum, or in a sort of free-context reality.
The two sides of Bounded rationality
Based on what we have said so far, let’s look again at the concept of bounded rationality. According to the definition given by his father, Simon, bounded rationality has two main sides:
ecologicaland cognitiveIt’s ecological because “the mind is adapted for real-world environments.” Therefore, on the one side, the mind makes decisions based on the structure of the environment. And on the other side, there is the computational capability of the decision-maker (cognitive side).
As highlighted by Gerd Gigerenzer and Wolfgang Gaissmaier in “Heuristic Decision Making modern psychologists have focused their attention on the latter (the cognitive side).
More precisely, the focus on the cognitive side has produced the misunderstanding that as the human mind has limited ability to process information, it produces a set of irreparable biases.
Part of this misunderstanding might be given by the fact that those presumably simple heuristics that the mind uses to solve real-world problems are not sophisticated enough to look interesting to the norms of classical rationality.
The importance of Ecological RationalityOnce you understand the other side of rationality, not the cognitive, but the ecological, it changes everything.
In an ecological rationality sense, less-is-more becomes a powerful heuristic to rely on in many of the real-world scenarios.
Less-is-more is about ignoring cues that not only make us worse decision-makers. It also means that after a certain point more information leads to worse decisions, even when the costs of acquiring that information are zero.
Redefining biasesIn the conventional view, a bias is a cognitive error the mind makes, which is due to our lack of understanding of the real world driven by classic rationality. In the alternative way to look at bounded rationality in a decision-making process, it needs to balance out bias and flexibility to produce overall an inference which is more effective than a system that has no biases at all!
In that scenario, less information, ignoring a big chunk of noisy information and make “biased decisions” might lead to better decision-making.
Building an adaptive toolbox for entrepreneursOnce you understand all the principles highlighted above, you start tinkering with simple algorithms, that we can call heuristics, extremely useful for the businessman who doesn’t want to fall trap of complex thinking for the sake of it.
The FourWeekMBA analysis and study into this adaptive toolbox has just started, and we’ll be looking more and more into a set of simple heuristics to use in different contexts, by starting from when it makes sense to use them in the first place.
There are a few contexts in the business world where gathering more information, data and complex models can indeed help build a successful company (like at an operational level). But there are many other places (strategy and vision) where those complex systems not only do not work but are harmful.
For the sake of having a better toolbox for directing your business in the right direction, we’ll continue our investigation!
