Maximizing overall equipment effectiveness and eliminating unplanned downtime
What is the difference between Lean production and Six Sigma?
Lean production addresses visible problems, while Six Sigma addresses less visible problems and requires advanced training and expertise
Study Notes
Lean Operating Systems: Principles, Tools, and Approaches
- Lean thinking eliminates waste in all forms and focuses on efficient flow of materials and information throughout the value chain.
- The four basic principles of lean are the elimination of waste, increased speed and response, improved quality, and reduced cost.
- Toyota Motors Company is classified into seven major categories of waste, including overproduction and production defects.
- Lean operating systems focus on quick and efficient responses, producing to customer demand, and addressing customer inquiries or problems.
- Eliminating defects and errors in all processes greatly improves speed, reduces variability, and supports the notion of continuous flow.
- Reducing waste and improving quality often reduces cost at the same time in a lean enterprise.
- Lean tools and approaches include 5S, visual controls, Single Minute Exchange Dies (SMED), batch and single-piece flow, quality at the source, continuous improvement initiatives, and Total Productive Maintenance (TPM).
- 5S is a methodology derived from Japanese terms that prioritize sorting, setting in order, shining, standardizing, and sustaining.
- SMED refers to the quick setup or changeover of tooling and fixtures in processes.
- Quality at the source requires doing it right the first time, and therefore eliminates the opportunities for waste.
- TPM seeks to maximize overall equipment effectiveness and eliminate unplanned downtime, create worker “ownership” of the equipment, and foster continuous efforts to improve equipment operation through employee involvement activities.
- Lean production addresses visible problems in processes, whereas Six Sigma is more concerned with less visible problems and requires advanced training and expertise. Integrating both approaches can improve business results, and Lean Six Sigma is often an important part of implementing a sustainability strategy.
