Lean Six Sigma Tools

There are many useful tools within Lean Six Sigma (LSS) toolbox. But a word of caution: Do Not Be Obsessed with Lean Six Sigma Tools !

For LSS implementation to be successful, there must be a balance between two important components of LSS – the hardware & the software. Hardware refers to the tools & techniques (such as value stream map, SIPOC, Statistics, FMEA, Poka Yoke etc), and software refers to the human side of the implementation.

Some of the common Lean Six Sigma Tools are as follows:

Define:
Process Thinking
Process Mapping
SIPOC
Value Stream Mapping VSM
Spaghetti Diagram
Value Analysis
Pareto Chart
Project Selection
Project Charter
Stakeholder Analysis
Voice of the Customer VOC
Kano Model
Critical to Quality (CTQs)
CTQ Tree Diagrams
Survey Construction
Quality Function Deployment

Measure:
Basic Statistics
Variable and Attribute Data
Sampling Plan
Measurement System Analysis MSA
Data Collection
Check Sheet
Bench-marking
Baseline DPMO & Sigma Conversion
Rolled Throughput Yield
Trend Chart
Histograms
Measuring Process Variability
Statistical Process Control
Rational Subgrouping
X and Moving Range Control Charts
Attribute Control Charts
X-bar and R Control Charts
Process Capability

Analyze:
Root Cause Analysis
Cause and Effect Diagrams (Fish-bone Charts)
Five-Whys Analysis
FMEA
Scatter Plots
Regression and Correlation Analysis
Multiple Regression
Logic Regression
Hypothesis Testing
Introduction to Hypothesis Testing
Confidence Intervals and Hypothesis Testing

TRIZ

Control:
mistake proofing ( Poka Yoke)
Control Plan
SPC Revisited
FMEA
5S
Visual management
Total Productive Maintenance TPM

Change Management:
Leadership
Tollgating Skills
Project Management
Deployment Skills
Reward & Recognition Skills
Team Development

Soft Skills

LSS has been implemented in many different industries with great success. Some of the industries are as follows:

• Lean Six Sigma in Manufacturing
• Lean Six Sigma in Service Industry
• Lean Six Sigma in Shared Service Centres (SSC)
• Lean Six Sigma in Continuous Process Industry
• Lean Six Sigma for Research & Development (R&D)
• Lean Six Sigma in Government / Public Sector
