Data Collection: Understand various methods for collecting primary and secondary data relevant to the project.
-
Process Mapping: Learn how to create detailed process flow diagrams (PFDs) to visualize current state processes, identifying inefficiencies and bottlenecks.
-
Key Performance Indicators (KPIs): Identify and define KPIs critical to the success of the project, ensuring they are aligned with strategic objectives.
4. Analyze Phase (20%)
During this phase, you’ll apply statistical tools to analyze data and identify root causes of problems. Key focus areas include:
-
Data Analysis: Master techniques for analyzing collected data using statistical software or tools like Minitab or JMP.
-
Root Cause Analysis (RCA): Learn different RCA methods such as the 5 Whys, Fishbone Diagramming (Ishika), and Cause and Effect (Fishbone) diagrams to uncover underlying causes of process variations.
5. Improve Phase (15%)
The "Improve" phase involves implementing solutions and ensuring their effectiveness. This section tests your:
-
Solution Selection: Evaluate potential solutions using decision trees, cost-benefit analysis, or other tools to select the most feasible and effective option.
-
Change Management: Understand the importance of change management in Six Sigma projects, including strategies for planning and executing changes successfully.
-
Pilot Testing: Learn how to design and conduct pilot tests to validate solutions before full-scale implementation.
