Good Strategy Bad Strategy: The Difference and Why It Matters

by Richard P. Rumelt

Healthy growth is not engineered. It is the outcome of growing demand for special capabilities or of expanded or extended capabilities. It is the outcome of a firm having superior products and skills. It is the reward for successful innovation, cleverness, efficiency, and creativity. This kind of growth is not just an industry phenomenon. It normally shows up as a gain in market share that is simultaneous with a superior rate of profit.

No one has an advantage at everything. Teams, organizations, and even nations have advantages in certain kinds of rivalry under particular conditions. The secret to using advantage is understanding this particularity. You must press where you have advantages and side-step situations in which you do not. You must exploit your rivals’ weaknesses and avoid leading with your own.

The basic definition of competitive advantage is straightforward. If your business can produce at a lower cost than can competitors, or if it can deliver more perceived value than can competitors, or a mix of the two, then you have a competitive advantage. Subtlety arrives when you realize that costs vary with product and application and that buyers differ in their locations, knowledge, tastes, and other characteristics. Thus, most advantages will extend only so far. For instance, Whole Foods has an advantage over Albertsons supermarkets only for certain products and only among grocery shoppers with good incomes who place a high value on organic and natural foods. Defining “sustainability” is trickier. For an advantage to be sustained, your competitors must not be able to duplicate it. Or, more precisely, they must not be able to duplicate the resources underlying it. For that you must possess what I term an “isolating mechanism,” such as a patent giving its holder the legally enforceable right to monopolize the use of a technology for a time.2 More complex forms of isolating mechanisms include reputations, commercial and social relationships, network effects,* dramatic economies of scale, and tacit knowledge and skill gained through experience.

It must have taken iron nerve to wait years for the strategy to work. “You are still looking five to ten years ahead?” I query. “It is one of the big benefits of being a private company. When I first bought these lands from major oil companies, they were looking ahead one quarter or one year. They wanted to get the assets ‘off their books’ to make their financial ratios look better. We can do more with these businesses because we don’t suffer the crazy pressures that are put on a public company.”

In particular, increasing value requires a strategy for progress on at least one of four different fronts: deepening advantages, broadening the extent of advantages, creating higher demand for advantaged products or services, or strengthening the isolating mechanisms that block easy replication and imitation by competitors.

First, management may mistakenly believe that improvement is a “natural” process or that it can be accomplished by pressure or incentives alone. As Frank Gilbreth pointed out in 1909, bricklayers had been laying bricks for thousands of years with essentially no improvement in tools and technique.5 By carefully studying the process, Gilbreth was able to more than double productivity without increasing anyone’s workload. By moving the supply pallets of bricks and mortar to chest height, hundreds or thousands of separate lifting movements per day by each bricklayer were avoided. By using a movable scaffold, skilled masons did not have to waste time carrying bricks up ladders. By making sure that mortar was the right consistency, masons could set and level a brick with a simple press of the hand instead of the time-honored multiple taps with a trowel. Gilbreth’s lesson, still fresh today, is that incentives alone are not enough. One must reexamine each aspect of product and process, casting aside the comfortable assumption that everyone knows what they are doing.

The second reason firms may fail to engage in a process of improvement occurs when isolating mechanisms surrounding important methods are weak. Companies in such situations sensibly hope to catch a free ride on the improvements of others. To benefit from investments in improvement, the improvements must either be protected or embedded in a business that is sufficiently special that its methods are of little use to rivals.

Extensions based on proprietary know-how benefit from the fact that knowledge is not “used up” when it is applied; it may even be enhanced. By contrast, extensions based on customer beliefs, such as brand names, relationships, and reputation, may be diluted or damaged by careless extension. Although great value can sometimes be created by extending these resources, a failure in the new arena can rebound to damage the core.
