Establish a long-term vision and strategy, like Toyota's 500-year strategic plan.

The Right Process Will Produce the Right Results

Use continuous flow to produce work to an even production level.
Level out workload to minimize waste, avoid overburdening people or equipment, and maintain even production levels.
Standardize tasks and processes to empower employees and facilitate continuous improvement.
Use visual control systems to ensure no problems are hidden.
Use only reliable technology that serves people and processes.

The 5S Program

Sort: Sort out unneeded items.
Straighten: Have a place for everything.
Shine: Keep the area clean.
