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.

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 most suitable for environments that are unpredictable and difficult to change. In these environments, it is difficult for companies to achieve sustainable competitive advantage pursuing the classical approach. Instead, companies aim to achieve a series of transient or short-term advantages by continually monitoring their environments and adjusting their objectives, updating their strategies, modifying their resources, and reconfiguring their capabilities.

The Strategy Palette framework was first published in Harvard Business Review (HBR) in by the lead author, Martin Reeves, and two colleagues, Claire Love and Philipp Tillmanns []. It had two dimensions: predictability and malleability; as well as four strategy approaches. Subsequently in , the framework was updated, and a third dimension was added called harshness, resulting in five strategy approaches. This updated version was published in the book “Your Strategy Needs a Strategy: How to Choose and Execute the Right Approach”, which was written by the lead author, Martin Reeves, and two new co-authors, Knut Haanaes and Janmejaya Sinha [].

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.
