Lean Manufacturing
No Comments Yet

Lean Manufacturing is an operational strategy oriented toward achieving the shortest possible cycle time while eliminating waste from the production process. It is derived from the Toyota Production System and its key thrust is to increase the value-added work by eliminating waste and reducing incidental work. The technique often decreases the time between a customer order and shipment, and it is designed to radically improve profitability, customer satisfaction, throughput time, and employee morale.

The benefits generally are lower costs, higher quality, and shorter lead times.  The term "lean manufacturing" is coined to represent half the human effort in the company, half the manufacturing space, half the investment in tools, and half the engineering hours to develop a new product in half the time.

The characteristics of lean processes are:

  • Single-piece production

  • Repetitive order characteristics

  • Just-In-Time materials/pull scheduling

  • Short cycle times

  • Quick changeover

  • Continuous flow work cells

  • Collocated machines, equipment, tools and people

  • Compressed space

  • Multi-skilled employees

  • Flexible workforce

  • Empowered employees

  • High first-pass yields with major reductions in defects

Lean Manufacturing incorporates the use of Heijunka, level sequential flow, Takt time, the heartbeat or pace of the production system, continuous flow manufacturing, cellular manufacturing, and pull production scheduling techniques such as Kanban.
