Issue:C-5 M Inner Piston high failure rate
Why:No standard process to identify and control rework
Action:Create standard work, perform root cause analysis on all rework, implement cause codes, install problem solving teams
Expected Results: Exceed Warfighters expectations, reduce rework/costs, Eliminate waste, reduce flow days, decrease WIP.

PIC Lean Activities:Office Kaizen Project
• Goals– Move orders though the
shop in a one-piece flow system
– Eliminate all NVA activities – Deliver orders to
manufacturing 4+ times per day
– Reduce cycle time for orders with non-forecasted seals from 1+ days to 30 minutes
Accomplishments
– Move orders in batches of 5 lines at a Takt time of 30 min/batch for continual flow
– Eliminated all identified NVA activities
– Delivering orders to manufacturing 8-10 times per day with a goal of 14
– Reduced cycle time for orders all orders to <1.5 hours (Based on WIP counts we showed a 860% cycle time reduction)
Emerson Electric China - SMT Kaizen Results
Schenzen, China – May 2003• Location : P1-1F (Machine #: MSH2)
•Purpose : Reduce set up time at Bottleneck Machine to increase capacity for entire plant
•Observation
• Set up team are in proper position.
• Each setup team member know their own task well.
• Material well prepared and can be plug in immediately.
• Little unnecessary movement.
• Result :
•March 26 set up time record -- 50 min.
•Demonstrated set up time -- 10 min.
• Saving of 40 min per set up. (80% saving)
Annual Savings:
40min * 10 setup/day * 21000 pcs/Hr * RMB 0.02 * 365 days = US$ 101,572
