The objective of this study is to construct an approach based on the fuzzy analytic hierarchy process (FAHP) and balanced score card (BSC) for evaluating an IT department in the manufacturing industry. The BSC concept is applied to define the hierarchy with four major perspectives (i.e. financial, customer, internal business process, and learning and growth), and performance indicators are selected for each perspective. A fuzzy AHP (FAHP) approach is then proposed in order to tolerate vagueness and ambiguity of information. A FAHP information system is finally constructed to facilitate the solving process. The results provide guidance to IT departments in the manufacturing industry regarding strategies for improving department performance. The constructed information system is suggested to be a good tool for solving other multiple- criteria decision- making problems.
