A Master Production Schedule (MPS) is a critical document that outlines the production plan for a manufacturing business. It includes information on all aspects of the production process, from raw material inventory to finished goods. However, there are other synonyms that can be used to refer to this important document, such as production plan, manufacturing schedule, production schedule, and production program. These terms are all used interchangeably to describe the MPS document. Regardless of what it is called, the MPS serves as a roadmap that outlines the production requirements and deadlines necessary to meet customer demands while maintaining optimal efficiency and cost-effectiveness in the manufacturing process.
