BCG’s Strategy Palette is based on three key contingent variables: unpredictability, malleability, and harshness, resulting in five strategy approaches: classical, adaptive, shaping, visionary, and renewal. It serves as a good introduction to strategy approaches and provides guidance on the relevant strategy tools that can be utilized for each approach. However, using only dichotomous variables makes this a more reductionist framework which does not lend itself towards capturing the different degrees of variation and complexity within the variables. Therefore, it does not allow for a more extensive and pertinent set of strategy approaches to be considered. 

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 strategy palette has three dichotomous variables – predictability, malleability, and harshness. Predictability is defined as the extent to which the organization can predict the key strategy variables in its environment which impact the focal strategic issues for the organization. It also relates to how far into the future the organization can make such predictions. Malleability is defined as the extent to which the organization and its competitors could influence these key strategy variables. Harshness refers to the ability to survive a harsh environment.

The classical strategy approach is most suitable for stable environments which are predictable, where the rules of competition or conduct are well-established, making them non-malleable. These predictable and non-malleable environments are continuations of the past. Hence, the bases for achieving sustainable competitive advantage are known and can be achieved through competitive positioning using differentiation or cost leadership through scale.

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.
