As a subset, LEAN can be deployed in any organization within the Kaizen or Heijunka and Lean for Service frameworks and covers comprehensive concepts as Lean analytics for Work Control Systems and Multi-layered Replenishment systems.
Achieving stability, flexibility and speed require enablers such as; 5S, VM, SMED, Muda, Poka Yoke, Flow and Balance, etc these are comprehensive but are only the standard tools within our toolkit.
Original Six Sigma values and techniques are undiminished
Six Sigma is now famous for its investigatory approach to solving problems using the DMAIC (Define, Measure, Analyse, Improve, Control) project management framework. DMAIC follows a natural flow of fact based discovery.
Just as impacting is the suite of MUST have quantitative decision making tools that sits in this framework. Measure systems analysis, statistical data analysis, lateral thinking techniques, team-based brainstorming tools and control and implementation techniques.
Lean Six Sigma also includes Design for Innovation; used when new product or process is required or a process is so broken that redesign is triggered. DMEDI (Define, Measure, Explore, Develop, Implement)
Genuine Lean Six Sigma skills and knowledge are very powerful and entirely in synergy.
