When production keeps running behind even though jobs are planned, the issue is often upstream. The schedule assumes one kind of flow, but the floor is operating under different constraints.

Job shop, batch, repetitive, continuous process, and hybrid workflows each behave differently under load. When your release rules, routing assumptions, and control points do not match the workflow type, work in process stalls, queues build up, and the schedule stops reflecting reality.

Batch Manufacturing Breaks When Setup and Staging Are Not Treated as Capacity

• Maintain staging queues with clear statuses, such as ready, waiting on material, and waiting on QA.
• Require QA signoff on the prior batch before releasing the next batch to the same resources.
• Define a batch size versus setup time rule so batching decisions are consistent and not improvised.
