The Boston Consulting Group has introduced The Strategy Palette which outlines five distinct approaches to business strategy, helping CEOs and top executives match their approach to the current business environment and execute effectively.

The Strategy Palette is explained in detail in the new book, Your Strategy Needs a Strategy by Martin Reeves, Knut Haanaes and Janmejaya Sinha (Harvard Business Review Press, 2015) and in a deliberately playful video.
Martin Reeves also gave an interesting TED Talk on the concept.
