This paper discusses the use of the analytic hierarchy process (AHP) in assigning weights to a group of elements. The weighting of elements has two major functions. First, it is employed to prioritize (rank) elements so that the key elements can be determined. This may for example help to establish the key measures for business performance. Second, assigning weight to selected measures (or criteria) may provide a more accurate judgement. It is, therefore, useful in making business decisions, such as the evaluation of alternative marketing strategies, the selection of candidates for jobs, etc. In addition, AHP employs a consistency test to purify the usable questionnaire responses and an iterative process to improve consistency, which differentiate it from other research methods. Comments and discussions regarding the AHP method are also provided.
