This chapter examines strategy as the central mechanism through which organizations align purpose, power, and action in contexts of uncertainty and competition. Rather than treating strategy as a purely analytical or planning exercise, it presents strategy as a unifying logic that connects values, vision, and mission with structures, systems, leadership, capabilities, and people. Drawing on classical and contemporary thinkers, the chapter shows that strategy is fundamentally about judgment, alignment, and coherence over time. Strategic success depends less on prediction and detailed plans than on the organization’s ability to resolve dilemmas, adapt to change, and coordinate behavior across multiple levels. Strategic failure, by contrast, is often the result of internal misalignment, contradictory signals, and loss of credibility rather than external pressure alone. The Enneagon Model provides a holistic framework to understand strategy’s central role, highlighting how strategic choices cascade across both hard and soft organizational dimensions. The OP-7D Model complements this view by making explicit the political nature of strategy: strategic decisions redistribute power, shape influence, structure communication, mobilize networks, and generate conflict. Politics is not a deviation from strategy, but its operating environment. Ultimately, the chapter argues that strategy is central because it performs a coherence function. When strategy is clear and aligned, it channels organizational energy toward shared objectives and sustains viability over time. When it is absent or contradictory, misalignment intensifies, conflict escalates, and the organization risks fragmentation.
