Bowman's Strategy Clock is a model used in marketing to analyse the competitive position of a company in comparison to the offerings of competitors. It was developed by Cliff Bowman and David Faulkner as an elaboration of the three Porter generic strategies. As with Porter's Generic Strategies, Bowman considers competitive advantage in relation to cost advantage or differentiation advantage. Bowman's Strategy Clock represents eight possible strategies in four quadrants defined by the axes of price and perceived added value. The resulting star shape is reminiscent of a clock face, giving this tool its name.
