Gap analysis is often used as a fundamental method in performance evaluation and benchmarking. However, gap analysis only deals one measure at a time. It is rare that one single measure can suffice for the purpose of performance evaluation (Camp, 1995). As a result, some multi-factor based gap analysis methods have been developed. e.g., Spider charts, AHP maturity index, and Z charts. Although gaps can be identified with respect to individual performance measures, it remains a challenging task to combine the multiple measures in the final stage. Therefore, benchmarking models that can deal with multiple performance measures and provide an integrated benchmarking measure are needed.
