This strategy approach is highly analytical and involves three key activities - analysis, planning, and executing. The emphasis here is on being efficient and optimal. The strategy methods, tools and techniques associated with it are well-known because this approach has and still enjoys wide adoption by organizations, business schools, and consulting firms. Out of the strategy tools that were surveyed, were identified as belonging to the classical approach. These strategy tools include SWOT, Cs, Porter’s five forces, BCG portfolio matrix, core competencies, resource-based view, value chain, and strategy maps.

Finally, the book and its accompanying website cover strategy tools and link them to the five strategy approaches, creating five strategy toolboxes. This is a good development but one with insufficient coverage of the available strategy tools. In my research on strategy tools covering the same period (-), I identified over strategy tools. Some of these strategy tools include backcasting [], business wargaming [], assumption-based planning [], strategy under uncertainty [], the three horizons framework [], strategy diamond [], portfolio of initiatives [], strategy as active waiting [], the strategy tripod framework [], and capabilities-driven strategy []. BCG’s narrow coverage of strategy tools combined with fewer strategy approaches results in limited and incomplete strategy toolboxes and consequently, inadequate strategy guidance.

Second, the mapping logic of the strategy approaches to the strategy space is questionable, as it assumes that the different states of the strategy space can only be served by one strategy approach. Mapping exercises are different from typology constructions which require mutually exclusive and comprehensively exhaustive (MECE) categories []. Strategy approaches do not have to be mutually exclusive (ME) in their coverage of the strategy space, but they should be comprehensively exhaustive (CE). For instance, the visionary strategy approach and most of the related tools associated with it, which are prescribed to predictable and malleable environments, can also be used in environments characterized by unpredictability and malleability.

The adaptive strategy approach is evolutionary, necessitating the creation of solution hypotheses and testing them through experiments, then selecting promising options and scaling them up. The emphasis here lies in creating strategic flexibility. BCG research has identified strategy tools that can be used with the adaptive approach. These strategy tools include time-based competition, first mover advantage, dynamic capabilities, strategy as simple rules, adaptive advantage, and transient competitive advantage.

First, the use of dichotomous variables (predictability, malleability, and harshness) has resulted in the creation of a limited, coarse-grained strategy space. This is problematic because it means that fewer strategy approaches are identified to cover the strategy possibilities space, and these approaches are broad (i.e., umbrella approaches). This has resulted in a loss of precision in guiding the selection of the appropriate strategy. Take for example the umbrella strategy approach of adaptation, which has been operationalized primarily through continuous experimentation. Within this umbrella approach, there are several approaches such as static and dynamic robust strategy approaches [], which would only be revealed if the predictability dimension incorporated a greater number of states. This would help create a richer, more textured, and nuanced strategy space which differentiates between the varying levels of uncertainty [].
