On Strategy (The Boston Consulting Group on Strategy / Perspectives on Strategy)

On Strategy collects several decades' worth of short strategic essays — BCG calls them "Perspectives," typically under 1,200 words each — written primarily by BCG founder Bruce D. Henderson and other senior BCG consultants between the late 1960s and the mid-2000s. Rather than a single continuous argument, the book is an anthology, organized thematically into sections covering the foundational logic of competitive strategy, portfolio and resource-allocation thinking, time and organizational structure as sources of advantage, and the evolution of strategic thinking as markets globalized and digitized. Read together, the essays trace both the founding logic of the modern strategy-consulting discipline and how BCG's own thinking evolved to meet new competitive conditions over nearly forty years.

The earliest and most foundational material, largely written by Henderson himself, lays out ideas that have become standard vocabulary in business strategy: the experience curve (the observation that unit costs tend to fall by a predictable percentage with each doubling of cumulative production), the growth-share matrix (BCG's famous framework classifying business units as "stars," "cash cows," "question marks," or "dogs" based on market growth and relative market share), and the concept of sustainable competitive advantage as the central object of strategic thinking. Henderson's central claim, developed across many of the earliest Perspectives, is that strategy is fundamentally about deliberately organizing a business to achieve and defend a durable point of differentiation from competitors, rather than simply pursuing efficiency or growth for their own sake.

A second major thread, developed by later BCG partners as markets grew more complex, extends this foundational logic into new terrain: time-based competition (arguing that speed of execution itself becomes a durable competitive advantage), deconstruction of value chains (as technology allowed previously integrated industries to fragment into specialized competitors), and rethinking corporate structure and capability as sources of advantage beyond simple market-share position. These later essays generally retain Henderson's core premise — that differentiation is the essence of strategy — while updating the mechanisms through which that differentiation can be built and sustained as competitive conditions changed.

Because the book is assembled from many short, independently written pieces rather than a single sustained argument, its cumulative value lies less in narrative coherence and more in giving readers direct access to the original articulation of ideas — the experience curve, the growth-share matrix, time-based competition — that have since become diffused, often in simplified or distorted form, throughout mainstream business thinking. Reading the originals, the book implicitly argues, corrects popularized misunderstandings of concepts like the BCG matrix that have often been taught more crudely than Henderson and his colleagues originally intended.
