Perfect Use Cases
Assembly Line Defect Investigations
When scrap rates spike or a customer complaint arrives, use this template to structure a rapid root cause session. The 6M layout ensures no failure category is overlooked.
Kaizen and Continuous Improvement Workshops
Facilitate lean manufacturing workshops with a visual cause-and-effect map your whole team can contribute to. Export and embed it in your improvement reports.
Supplier Quality Reviews
Document and communicate incoming material nonconformances to suppliers using the Material and Measurement categories as a shared reference framework.
Preventive Maintenance Planning
Use the Machine and Method branches to identify equipment and procedure gaps before they cause unplanned downtime or out-of-tolerance parts.
How to Customize This Template
Define Your Problem Statement
Replace 'Assembly Line Defect Rate Increase' in the Effect label with the specific quality issue you are investigating — such as 'Weld Porosity on Line 3' or 'Dimensional Nonconformance in Batch 47'.
Edit or Add Cause Categories and Sub-Causes
Click any bone to update a sub-cause, remove causes that do not apply to your process, or add new ones uncovered during your team brainstorm. You can also rename categories to match your plant's terminology.
Style for Your Audience
Adjust colors to match your company brand or quality system color codes, increase font sizes for shop floor display, and download as a high-resolution image to share in reports or present on screen.
