On-site interviews conducted with the top management of 6 manufacturing firms can help identify critical relationships and patterns between their successful use of Material Requirements Planning (MRP) and Just-In-Time (JIT) methods in their bid to achieve superior results in production planning and control. Based on the findings, in no case was JIT operating without MRP, even though some management initially desired that end. Thus, it appears that MRP provides elements that JIT cannot. Additionally, in no case was MRP's SFC output found to be sufficient to manage priority control or capacity control. JIT methods established the stage where MRP was not useful in scheduling the shop floor. In general, MRP provides a necessary condition from which JIT methods can be used to successfully manage production.
