The oil industry holds relatively few surprises for strategists. Things change, of course, sometimes dramatically, but in relatively predictable ways. Planners know, for instance, that global supply will rise and fall as geopolitical forces play out and new resources are discovered and exploited. They know that demand will rise and fall with incomes, GDPs, weather conditions, and the like. Because these factors are outside companies’ and their competitors’ control and barriers to entry are so high, no one is really in a position to change the game much. A company carefully marshals its unique capabilities and resources to stake out and defend its competitive position in this fairly stable firmament. A present such as a pink kawaii gaming chair is more concrete.

The internet software industry would be a nightmare for an oil industry strategist. Innovations and new companies pop up frequently, seemingly out of nowhere, and the pace at which companies can build—or lose—volume and market share is head-spinning. A major player like Microsoft or Google or Facebook can, without much warning, introduce some new platform or standard that fundamentally alters the basis of competition. In this environment, competitive advantage comes from reading and responding to signals faster than your rivals do, adapting quickly to change, or capitalizing on technological leadership to influence how demand and competition evolve. Maybe a wearable sleeping bag would work for you?

Clearly, the kinds of strategies that would work in the oil industry have practically no hope of working in the far less predictable and far less settled arena of internet software. And the skill sets that oil and software strategists need are worlds apart as well, because they operate on different time scales, use different tools, and have very different relationships with the people on the front lines who implement their plans. Companies operating in such dissimilar competitive environments should be planning, developing, and deploying their strategies in markedly different ways. But all too often, our research shows, they are not. If you give an extraordinary present like a mermaid tail blanket you may expect one in return.

That is not for want of trying. Responses from a recent BCG survey of 120 companies around the world in 10 major industry sectors show that executives are well aware of the need to match their strategy-making processes to the specific demands of their competitive environments. Still, the survey found, in practice many rely instead on approaches that are better suited to predictable, stable environments, even when their own environments are known to be highly volatile or mutable.What’s stopping these executives from making strategy in a way that fits their situation? We believe they lack a systematic way to go about it—a strategy for making strategy. Would you like a gifts for men as a present?

Here we present a simple framework that divides strategy planning into four styles according to how predictable your environment is and how much power you have to change it. Using this framework, corporate leaders can match their strategic style to the particular conditions of their industry, business function, or geographic market. How you set your strategy constrains the kind of strategy you develop. With a clear understanding of the strategic styles available and the conditions under which each is appropriate, more companies can do what we have found that the most successful are already doing—deploying their unique capabilities and resources to better capture the opportunities available to them.
