Goal of Lean Operations
One that achieves a smooth, rapid flow of materials and/or work through the system
Balanced system
A manufacturing or service unit consisting of a number of workstations and the materials transport mechanisms and storage buffers that interconnect them
Lean Manufacturing Cells
What are three supporting goals of lean operations?
1) Eliminate disruptions
2) Make system flexible
3) Eliminate waste
How do you improve waste?
Kaizen
What are the four building blocks for lean operations?
1) Product design
2) Process design
3) Personnel/Organizational elements

1
A system for reducing changeover time
Single minute exchange of die (SMED)
Automation detection of defects during production
Automation (jidoka)
The cycle time needed to match customer demand for final product
Takt time
Building safeguards into a process to reduce or eliminate the potential for errors
Poka-yoke (Fail Safeing)
Well trained and motivated workers are the heart of the lean system
Workers as assets
Parts of a process and operate a variety of machines
Cross-trained workers
Allocation of overhead to specific jobs based on their percentage of activities
Activity-based costing
Work is pushed to the next station as it is completed
Push system
A workstation pulls output from the preceding workstation as it is needed (kanban)
Pull system
A card or other visual device that communicates demand for work or materials from the preceding station
Kanban
Signals the need to produce parts
Production Kanban (p-kanban)
Signals the need to deliver parts to the next work center
Conveyance Kanban (c-kanban)
Maintaining equipment in good operating condition and replacing parts that have a tendency to fail before they actually do fail
Preventative Maintenance
Maintaining a workplace that is clean and free of unnecessary materials
Housekeeping
Enhanced flow chart including times distances, work methods, wait times, etc. Goal is to eliminate non-value added activities
Value Streaming Mapping (VSM)
A supplier representative works in the company’s plant, insuring appropriate supply on hand
