Strategic Matrix Analysis (SMA) is a conceptual tool in business strategy analysis and decision making. STRATEGIC POSTURE and INDUSTRY VALUE CHAIN are the two dimensions of the strategic matrix. Strategic posture consists of six items: product charateristics and scope, segmentation and targeting of markets, degree of vertical integration, relative scale and economies of scale, geographic dispersion, and competitive weapon. The industry value chain is the collection of all relevant value activities in a specific industry, including those value activities provided by up-stream and down-stream firms, indirect influencers of buying decisions, and institutional buyers. The linkages, interactions and interfaces between and among cells in the strategic matrix form many STRATEGIC ESSENCE. Theoretically, most of the strategic concepts and actions can be described by the use of strategic matrix and strategic essence. In this paper, thirty (30) essences of strategy were given as examples. Under this analytical framework, strategies are, in fact, selected sets of strategic essences. Through the SMA approach, the strategy can be very specific and easy to integrate with many theories in strategic managment.
