Production Planning Problems: Diagnose the Missing Record

Diagnose production-planning problems by tracing a missed commitment to the material, capacity, instruction or status record that supported the plan. A job finishing late is a symptom; the next check should identify the assumption that stopped being true.

Start with one delayed order. Keep its original commitment, released quantity and plan version visible. Ask what the planner knew at release and what changed afterward. Avoid replacing the old date before recording the reason, or the team loses the evidence needed to investigate.

Match the symptom to a record

The hypotheses in this worksheet need evidence. A late update may reflect a device problem, unclear responsibility or an operating rule; it is not proof that an operator ignored the process.

Separate demand, feasibility and execution

Demand states what must be supplied and when. Feasibility checks whether the required material, resources and instructions can support that commitment. Execution records what happened. Keep these three views connected, with clear timestamps and ownership.

ERPNext's production-plan documentation provides a reference for connecting demand and material requirements. The production-planning worked example shows how material and machine time can constrain the same job independently.

Investigate one discrepancy before changing every plan

For an illustrative case, a receipt appears in the store register but production still reports a shortage. Inspect the item, unit, location, inspection status and reservation before assuming the planning calculation is wrong. The delivery may have arrived physically while part of it remains held for inspection.

Record the expected value, observed value, source record and responsible reviewer. Correct the underlying record only through its approved process. If material really is unavailable, identify the jobs depending on it and ask the planner to revise those commitments.

Publish a controlled plan revision

1. State the changed fact and when it was confirmed.
2. List affected jobs, quantities and downstream commitments.
3. Compare feasible alternatives with the relevant material and resource owners.
4. Approve the selected action and retain the previous plan.
5. Communicate the current version and the next exception-review time.

A private spreadsheet and a printed job card can both be internally consistent while showing different revisions. Agree where the current approved plan lives and how the floor learns that an instruction has changed.

Measure a defined operating problem

Choose a measure with an explicit denominator: jobs started on their approved start date, jobs delayed by a verified material shortage, or updates entered within the agreed time. Keep the population and period consistent. A rise in logged delays after a reporting change may represent better capture rather than worse operations.

In an Optiwise production review, bring one delayed order and ask to trace its material, capacity and status evidence. Use the implementation gate sheet to assign responsibility for any missing input or unresolved configuration.

Questions from manufacturing teams

What usually causes production-planning problems?

Possible causes include incorrect material availability, omitted capacity constraints, changing instructions and stale execution records. Investigate the specific order and source evidence before choosing a cause.

Should we replan whenever a dashboard shows a delay?

First confirm the source event and its effect on the commitment. If a material or capacity assumption has changed, revise the affected plan through the agreed approval and communication process.

Which planning metric should we start with?

Choose a defined problem your team can act on, such as verified material-shortage delays or on-time starts. State the population, period, timestamp rules and owner so comparisons remain meaningful.
