Challenge
Daily deliveries by express transports waiting for reworked parts to be finished, highly complex rework process, exclusively by contracted and expensive technicians.
Strategy Applied
Strategic problem solving, combination of Shainin Red-X and Six Sigma Yellow Belt – focus on top 3 responsible for 80% of rework time.
Results
FTQ (% of good parts produced ) improved from 0 to 50%, on plan to 70%; Average rework time from 5h/part to below 15′; bottleneck eliminated, no more delivery issue.
