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 link-ages tell us which CSFs to emphasize at various stages of the project.
