Question 118 - CPIM-Part-2 discussion

Production activity control (PAC) is the function of managing the flow of materials and work-in-progress in a manufacturing system. PAC is responsible for executing the master production schedule and the material requirements plan, as well as for planning, implementing, and monitoring the production activities. PAC aims to ensure that the required resources are available, that the production orders are released and completed on time, and that the quality and quantity standards are met. A result of effective PAC is that the actual input/output matches the planned input/output. This means that the actual amount and timing of materials, labor, and machines used for production are consistent with the planned amount and timing. This indicates that the production process is efficient, reliable, and synchronized with the demand. This also helps to reduce inventory, lead time, and waste.

The other options are not necessarily results of effective PAC. Less scrap and rework on the shop floor may be a result of effective quality control, which is a separate function from PAC. Quality control is concerned with inspecting and testing the products or services to ensure that they meet the specifications and standards. Fewer machine hours are required for production may be a result of effective process improvement, which is a separate function from PAC. Process improvement is concerned with analyzing and enhancing the production methods and techniques to increase productivity and performance. Available capacity is increased may be a result of effective capacity planning, which is a separate function from PAC. Capacity planning is concerned with determining and adjusting the optimal level of resources needed to meet the demand.Reference:Production Activity Control - Tutorial;Production Control: Process, Types and Best Practices - ProjectManager;Production control - Wikipedia.
