A multiple-case design methodology for studying MRP success and CSFs

We used a multiple-case design to study materials requirements planning (MRP) implementation outcome in 10 manufacturing companies in Singapore. Using a two-phased data collection approach (pre-interview questionnaires and personal interviews), we sought to develop a comprehensive and operationally acceptable measure of MRP success. Our measure consists of two linked components. They are a satisfaction score (a quantitative measure) and a complementary measure based on comments from the interviewees regarding the level of usage and acceptance of the system. We also extended and consolidated a seven-factor critical success factor (CSF) framework using this methodology. CSFs are important, but knowing the linkages between them is even more important, because these linkages tell us which CSFs to emphasize at various stages of the project.
