Step 4
Determine the Attractiveness Scores (AS), defined as numerical values that indicate the relative attractiveness of each strategy in a given set of alternatives. Attractiveness Scores are determined by examining each key[linkunit] external or internal factor, one at a time, and asking the question, “Does this factor affect the choice of strategies being made?” If the answer to this question is yes, then the strategies should be compared relative to that key factor. Specifically, Attractiveness Scores should be assigned to each strategy to indicate the relative attractiveness of one strategy over others, considering the particular factor. The range for Attractiveness Scores is 1 = not attractive, 2 = somewhat attractive, 3 = reasonably attractive, and 4 = highly attractive. If the answer to the above question is no, indicating that the respective key factor has no effect upon the specific choice being made, then do not assign Attractiveness Scores to the strategies in that set. Use a dash to indicate that the key factor does not affect the choice being made. Note: If you assign an AS score to one strategy, then assign AS score(s) to the other. In other words, if one strategy receives a dash, then all others must receive a dash in a given row.
Step 5
Compute the Total Attractiveness Scores. Total Attractiveness Scores are defined as the product of multiplying the weights (Step 2) by the Attractiveness Scores (Step 4) in each row. The Total Attractiveness Scores indicate the relative attractiveness of each alternative strategy, considering only the impact of the adjacent external or internal critical success factor. The higher the Total Attractiveness Score, the more attractive the strategic alternative (considering only the adjacent critical success factor).
Step 6
Compute the Sum Total Attractiveness Score. Add Total Attractiveness Scores in each strategy column of the QSPM. The Sum Total Attractiveness Scores reveal which strategy is most attractive in each set of alternatives. Higher scores indicate more attractive strategies, considering all the relevant external and internal factors that could affect the strategic decisions. The magnitude of the difference between the Sum Total Attractiveness Scores in a given set of strategic alternatives indicates the relative desirability of one strategy over another.
Limitations of QSPM
A limitation of the QSPM is that it can be only as good as the prerequisite information and matching analyses upon which it is based. Another limitation is that it requires good judgment in assigning attractiveness scores. Also, the sum total attractiveness scores can be really close such that a final decision is not clear. Like all analytical tools however, the QSPM should not dictate decisions but rather should be developed as input into the owner’s final decision.
Advantages of QSPM
A QSPM provides a framework to prioritize the strategies, it can be used for comparing strategies at any level such as corporate, business and functional.The other positive feature of QSPM that it integrate external and internal factors into decision making process.A QSPM can be developed for small and large scale profit and non-profit organizations.
