Question:
The requirements elicitation process performed for an aircraft manufacturing company uncovered the following facts. The company employs MRP to determine what jobs are to be released to the shop floor for processing, when, and when they are due. The entire process is described as follows:
a. MRP records are generated, based upon aggregate production plans received from Production Planning. Process plans, product data, and shop capacity data are all required for generating MRP records.
b. Following MRP generation, work orders (WO's) are prepared for jobs to be released the next week, based upon the MRP records. Completed WO's are placed in a file.
c. When it is time to prepare and release a job, the WO is copied from the file, and then travels with the items to the shop floor.
d. The job is then processed in the shop.
e. Once the job is complete, the WO is closed-out (removed from the WO file). The MRP records are also updated.
