Separate rules from objectives
Equipment matching, operation dependencies, and calendars are generally mandatory rules. Delivery risk, resource loads, and adjustment costs need evaluation against business goals. Distinguishing the two helps explain why a candidate is feasible and why it is worth adopting.
Turn experience into verifiable inputs
Planners know which machine fits an operation and when overtime is possible. Implementation translates that experience into resource matching, calendars, and freezes, then validates it with representative orders. Missing inputs should not be hidden by changing display numbers.
Review candidates against real situations
Use delivery conflicts, rush orders, breakdowns, and shortages to examine operations and resource allocations. Candidates should expose their input version, pending tasks, and risks so planners can review and explain the result.
Constraints change with the floor
Material arrivals, equipment recovery, and execution feedback all change availability. Starts and remaining processing time should inform the next snapshot, replacing assumptions with actual progress.
