2. Six Sigma
   1. WHAT
      1. a series of phases in order to reach the root causes of the problem, eliminating the impact, and making sure that the solution is sustained
   2. WHY
      1. to ensure that the process has minimum defects
   3. DMAIC
      1. Define
         1. the problem, improvement activity, opportunity for improvement, the project goals, and customer (internal and external) requirements
            1. Activities
            2. Launch Team
            3. Establish charter
            4. identify the problem that requires improvement
            5. to understand the issues as a whole and understand the customers’ preferences
            6. Plan project
            7. define the issues and the action plan required to achieve the results
            8. use available data
            9. Summary
            10. Prioritize: high, low, medium
            11. Understand the areas where it will impact example
            12. Gather the Voice of the Customer
            13. Get an idea of the available resources
            14. Plan for Change
      2. Measure
         1. process performance
            1. Activities
            2. Document the process
            3. progress and performance
            4. define “current stage” ---->baseline
            5. to measure the improvements made in the project
            6. Collect BaseLine measurable Data
            7. to analyze the root cause of the waste
            8. confirmed source
            9. update the data regularly
            10. Narrow project focus
      3. Analyse
         1. the process to determine root causes of variation and poor performance (defects)
            1. Activities
            2. Analyze Data
            3. with Team
            4. share viewpoints to add value to the whole process
            5. Identify Root Cause
            6. the main goal
            7. Identify and eliminate wastes
            8. Time
            9. How well the project members utilize the time
            10. Are there any lags due to long unnecessary breaks?
            11. Is there any other reason that drags the project off its stipulated timeline?
            12. Value
            13. How well is the project moving towards achieving customer satisfaction?
            14. How is it adding value in terms of efficiency and high-quality product?
            15. Value Stream Mapping
            16. map the process and identify the areas where the waste processes
            17. to make informed decisions to add or delete a particular step
      4. Improve
         1. process performance by addressing and eliminating the root causes
            1. Activities
            2. Generate Solutions
            3. to fix root cause
            4. improvements need to be implemented at the right time to get the desired results
            5. need to prepare a proper plan of action
            6. solutions need to be practical
