Probe the concept of "interchangeability" with technicians. Ask for records of past incidents where employees have escalated violations on CE that made it to the line. Verify that there is an Engineering Change link with the floor to prepare technicians for a change in the product so they can anticipate the change and are concerned when an unanticipated change comes through.SCORING:0 = Not 100% of employees (need to know) are trained on copy exact and interchangeability1 = Trained. But no/ minimal evidence of escalated violations. Aware of ECR process they encounter in the assembly process2 = Trained and recertification evidence of Copy exact and change control. Enough evidence of escalation violation that employees have brought to the attention of management
