The ultimate guide to strategy

Strategy is the set of integrated choices about where an organisation will compete and how it will win — the disciplined allocation of scarce resources to build a durable competitive advantage. Good strategy is not a plan, a vision, or a list of goals; it is a diagnosis of the real challenge, a guiding policy, and a coherent set of actions. This guide covers:

• The definition, history and purpose of strategy — and how it differs from tactics and planning.
• The cognitive discipline of strategic thinking and a repeatable planning process.
• The analysis that informs choices and the 15+ frameworks that structure it, with a selection guide.
• How consultants solve and communicate strategy, how executives decide, and how to close the execution gap.
• The mistakes that sink strategies, the practices that make them work, and where strategy is heading in the AI era.

What is strategy?

Strategy is one of the most used and least understood words in business. Executives invoke it to dignify budgets, plans and aspirations that are none of these things. Getting the definition right is the first strategic act.

Strategy definition:

a coherent set of choices about where an organisation will compete and how it will win — the deliberate allocation of scarce resources to create and sustain a competitive advantage. A strategy is defined as much by what you choose not to do as by what you do.

Definition from the field

Strategy has several complementary definitions, each illuminating a different facet:

• Michael Porter argued that strategy is about being different: "deliberately choosing a different set of activities to deliver a unique mix of value." Its essence is trade-offs — deciding what not to do.
• Henry Mintzberg observed that strategy shows up in five forms — the "5 Ps": a Plan (intended direction), a Pattern (consistency in behaviour over time), a Position (a place in the market), a Perspective (a way of seeing the world), and a Ploy (a specific manoeuvre to outwit a rival).
• Richard Rumelt defined the "kernel" of good strategy as three elements: a diagnosis of the challenge, a guiding policy for dealing with it, and a set of coherent actions to carry out the policy. Everything else — mission statements, goals, financial targets — is not strategy.
• Roger Martin & A.G. Lafley framed strategy as an integrated cascade of five choices: a winning aspiration, where to play, how to win, the capabilities required, and the management systems to support them.

These views converge on a single idea: strategy is about making hard, integrated choices under uncertainty to achieve advantage. It is not a wish, a forecast, or an operational plan.

A brief history of strategy

The word derives from the Greek strategos — the art of the general. Its intellectual lineage runs from the battlefield to the boardroom.
