Issues: n Bill of Materials: Determines components, quantities and lead times. n Inventory Management: Must be coordinated with inventory. Production Planning 8

Sequencing and Scheduling o o Objective: develop a plan to guide the release of work into the system and coordination with needed resources (e. g. , machines, staffing, materials). Methods: n Sequencing: o n Gives order of releases but not times. Scheduling: o Gives detailed release times. Production Planning 9
