If anyone that is reading my reviews is looking for a particularly meaty de Bono book, this is it? He goes into detail explaining particular methods, how to perform them, how they're supposed to work on a mechanical level, what to avoid in executing them, etc. The people who reviewed this book, pointing out that all of this exist in design thinking, missed the point. Whatever overlap they have, they are fundamentally different bodies of practice. This technology is a lot less restricted in its potential applications.
Key points:
- The brain is a mechanism that uses past inputs to process future inputs and thus has the habit of getting stuck into ruts. Exploratory work, such as research, does not lead to new concepts but rather just follows existing pathways in the brain and makes new constructions out of existing concepts.
- In order to navigate to novelty, we have to use approaches that take us far away from the beaten path and work our way back.
- All novel approaches look logical in hindsight and so people assume that you can reach them using logic but you cannot.
- From the appendix, here are the basic functions of the tools that de Bono lays out:
Focus and subfocuses
Alternatives and elaborated alternatives (concept fan)
Challenge to the existing
Escape from the existing
Radical rethinking (stepping-stone)
Fresh ideas and new start (random word)
Sensitization (stratal and filament technique)
- The methods themselves, by name are:
Improvement Thinking
Challenge
Alternatives
Escape
Greenfield Thinking
Random Input
Stratals
The filament technique
Wishful thinking
Organizational thinking
Distortion
For my own purposes in reading this review in the future, I'll write a brief summary of each method inasmuch as I can remember.
Concept fan: A logical exploration of ideaspace. In de Bono's usage, idea means application and concept means the abstraction being applied. One of the examples from the book is that a straw is a way to move fluid. So the straw is the application. Moving fluid is the concept. We work backward from ideas to concepts and then go from concepts to ideas to discover alternatives. This happens in layers (hence a fan shape). So, you might say that moving fluid is actually the idea. How do we accomplish that? Pressure differentials. So pressure differentials are the concept. Now how can we use that? That leads us to the next alternative idea, up and down the layers of abstraction.
Challenge: Challenge techniques are meant to break lock-in from the various inertial forces that build up in people's minds and organizations. It asks why a particular thing needs to be done or needs to be done a particular way, then generates hypothetical scenarios to discover alternatives that we would normally gloss over.
Stratals: Essentially this technique involves a random assortment of attributes of the subject you're hoping to innovate around. You cannot select or in any way filter the randomization process here. You get what you get and you use what you get to generate novel ideas, ignoring all other attributes you may have in mind (more on that in harvesting methods).
Filament: My take on this is that it is a deconstruction-reconstruction method. You take each of the requirements for the thing you're trying to innovate and you consider how to satisfy the requirement entirely absent the current context. After you do that, you recombine those independent concepts into a new idea.
Random word: Basically, you get a completely random word and you consider that word entirely divorced from your current concept. Think around that word. Then, take the things you thought around that word and attempt to build a bridge back to the idea you're working on.
Escape: I treat escape as a special case of challenge. Basically, you identify things you take for granted about the subject you're focusing on (similar to both stratals and filaments) and then you cancel it. So, paper but you can't write on it. You go from there.
I recommend this book to anyone that is doing any sort of work that requires independent design. Whether it be programming, conducting experiments, marketing, art, writing, law, it doesn't really matter. Read the book. Use the techniques.
