Decision stage is the last stage of strategy formulation in which a tool is used called Quantitative Strategic Planning Matrix or QSPM Matrix. Hence there are a number of alternative strategies and the Quantitative Strategic Planning Matrix (QSPM). Actually that can be used to objectively evaluate the most suitable strategy among the list of all the alternative strategies. Therefore the data is collected and a matrix is developed by using quantitative methods for strategic planning. Thus the identification of the external and internal crucial success factor is regarded as the basis of QSPM Matrix. Since the relative attractiveness of feasible alternative action can be determined by only the specially designed technique of QSPM Matrix.
