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.

eLog21 Goal alignment: Increase aircraft availability by 20%

• 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
