Lean Six Sigma Flashcards
Lean Six Sigma summary
magangement concept combining philosophies of Lean and Six Sigma to eliminate wasteful tasks, ensure continuous improvement, reduce defects and add value and make process flow customer oriented
Lean overview
Derived from TPS
Focus - eliminate waste and smooth production flow without sacrificing quality
NOT about cutting costs
Six Sigma overview
Developed by Motorola
Seeks to improve processes by reducing defects and variation with emphasis on making decisions informed by data
For a process to be performing at 6 sigma it must have just 3.4 defects for each million
Steps in Lean methodology
- Identify customers and quantify value from their standpoint
- Respond to customer pull
- Seek perfection (always more to be done)
- Identify map and value stream
- Create flow by eliminating waste organising remaining steps into best sequence
Steps in 6 Sigma (DMAIC)
D - Define the problem, improvement opportunities, goals and customer reqs (Project charters, customer feedback and value stream maps)
M - Measure Process Performance (process maps, pareto analysis, capability analysis
A - Analyse the process to determine causes of problems (Root cause analysis, Multi-Vari chart, FMEA)
I - Improve process performance by addressing root cause (DOEs and Kaizen events)
C - Control the improved process plan (QC plan, 5s, Statistical Process Control )
Lean 6 Sigma mission statement
Produce products which surpass customer expectations in an efficient and waste-free way
Continuous drive to identify and eliminate waste and enable continuous ipmrovement
Lean 6 Sigma Hierarchy
White belt - Have an awareness of LSS methods and tools
Yellow belt - Aware of the underlying LSS philosophy and act as a team member beneath a green belt
Green belt - Small-scale improvement experts capable of leading small projects and mentoring yellow belts. Firm understanding of DMAIC
Black belt -
