Define: What is the problem?
Measure: What is the frequency of defects?
Analyze: Where and why does the defect occur?
Improve: How can we fix the process?
Control: How can we make the process stay fixed?
Each of the Six-Sigma™ phases contains a set of tools that can be used throughout the entire project. Each of these tools is designed for a specific objective. Make sure you are familiar with the tool before you apply it otherwise your result might be unpredictable and not repeatable. These tools can be used in multiple phases of the Six-Sigma™ project. Below you can see a list of the tools available within each of the Six-Sigma™ phases (note this is not a comprehensive list of tools).
Define: Process Map, Product Tree, FMEA, QFD, Surveys, and Pareto Chart.
Measure: Six-Sigma™ Macro, Events/Causals, Histogram, Benchmarking, L1 Worksheet, and Gage R&R.
Analyze: Fishbone, Brainstorming, 5 Why’s, Run Charts, Hypothesis Test, Pareto, and Regression.
Improve: ANOVA, Response Surface, DoE, EHS Checklist, ISO checklist, Interactions Plots, and Response Equation.
Control: Risk Management, Mistake Proofing, SPC Charts, Procedures, Training, and Quality Management Systems.

six sigma originated as a set of practices designed to improve manufacturing processes and eliminate defects, but its application was subsequently extended to other types of business processes as well.
