Project Manufacturing
Project Manufacturing is a manufacturing and supply chain management approach in which materials, work orders, procurement, inventory, and costing are controlled by a specific project, contract, or Seiban number rather than only by plant-wide or item-wide inventory buckets. It maintains project-specific supply, demand, inventory, procurement, shop floor execution, and costing visibility.
In practice, Project Manufacturing prevents a common shop-floor problem: identical components for different customer programs sitting in the same bin. When a work order is released, the system issues material against a specific project, contract, or Seiban number, so operators, kitting, and WIP remain attributable to that job. In warehousing, project-tagged receipts and locators keep inbound material separate, and picking or transfers deduct from the correct project bucket rather than general stock. Procurement documents carry the project reference, so receiving immediately updates project cost and availability. Planning then separates supply and demand by project, while distinguishing shared components from dedicated ones. This lets planners trace shortages, delays, and cost impact through one structure, which is essential in high-mix, low-volume, ETO, MTO, and A&D environments where mixing material across contracts creates audit failures, false shortages, and misallocated costs.
- Cross-project material leakage: A project-specific component gets issued from general stock or received into the wrong project bucket, destroying traceability, corrupting inventory balances, and triggering false shortages or cost misallocation.
- Receiving bottlenecks with project-tagged material: Inbound POs arrive without the correct project reference or locator, so receiving stalls while materials wait for manual correction, delaying shop-floor release and increasing idle time.
- Shared-versus-dedicated component confusion: MRP treats a project-reserved component as shared or a common part as dedicated, causing stockout risk on the project or excess, stranded inventory from missing project-context separation.
How is Project Manufacturing different from standard MRP?
Standard MRP plans by item and location; Project Manufacturing adds a project dimension so supply, demand, inventory, and cost are controlled and visible at the project level, preventing cross-project contamination.
What is the main data structure behind it?
A project number, contract number, or Seiban number acts as the control key tying inventory, procurement, work orders, and costing together, enabling project-specific visibility and traceability.
Why is project inventory segregation important?
It prevents commingling of material across contracts, supports auditability, and enables correct project cost capture and fulfillment tracking, which is critical in ETO, MTO, and Aerospace/Defense operations.
