Henry Mintzberg, 1978

“Strategy is a pattern in a stream of decisions.”

Henry Mintzberg used this definition in his research on how strategies actually form inside organizations. Conventional planning often describes strategy as an intention announced before action. Mintzberg examined sequences of real decisions and found that a recognizable direction can also emerge through consistent behavior, whether or not leaders originally planned it. The definition distinguishes intended strategy from realized strategy. A company’s presentations may promise one future, while its hiring, investment, pricing, and product choices create another. Strategy is visible in the pattern of commitments, not only in the language used to justify them.

This perspective gives managers a practical audit. List the major decisions made during the last year, including projects funded, customers prioritized, capabilities hired, exceptions approved, and activities stopped. The pattern may reveal a coherent position—or show resources scattered across incompatible ambitions. Emergent strategy is especially useful when uncertainty makes detailed prediction unreliable. Small actions can produce learning, and a successful pattern can later be recognized, strengthened, and explained. Deliberate planning and emergence become complements: direction provides boundaries while experience supplies information the plan could not contain.

A pattern is not automatically a good strategy. Repeated decisions may reflect inertia, internal politics, or a succession of local compromises. Looking backward can also invent coherence that participants never possessed. Leaders still need diagnosis, choice, and a view of the value they intend to create. Mintzberg’s definition is most helpful when it exposes the gap between claims and conduct, then prompts a judgment about whether the observed pattern deserves continuation. Realization describes what happened; it does not excuse leaders from evaluating its consequences.

The idea fits product organizations that learn through experiments and businesses adapting to volatile demand. Portfolio reviews can compare declared priorities with actual engineering time, capital, executive attention, and customer commitments. Teams can mark which decisions were deliberate, which emerged from evidence, and which persisted only because no one revisited them. If the pattern creates advantage and aligns with purpose, leaders can reinforce it. If it contradicts the stated direction, they must change either the actions or the claim. Mintzberg makes strategy testable by asking the organization to read its own footprints. Quarterly reviews can include a one-page “strategy observed” alongside the official plan. It lists the largest irreversible commitments and the recurring pattern they imply. Leaders then decide whether to reinforce, stop, or reinterpret that pattern. The exercise gives emergent learning a legitimate path into strategy while preventing accidental accumulation from being praised as adaptability simply because it has already consumed resources.
