Workplace case

A warehouse reports a recurring failure related to demand, lead time and data quality. The team must contain the immediate risk, compare the physical condition with the system record, identify the cause and document the authorised correction.

Practical assignment

Create a one-page operating checklist for demand, lead time and data quality. Include the trigger, responsible person, required data, checks, exception route, evidence of completion and one performance measure.

Self-check: What proves that demand, lead time and data quality has been completed correctly?

Answer: The physical result, system transaction, status, location, quantity and supporting record must agree; unresolved exceptions remain contained and assigned to an authorised owner.
