Lean Six Sigma Green Belt works through a simple method known as DMAIC. The method is designed in a way that helps teams solve real business problems in an organised way. It helps teams understand the problem first and then help them find the best solution to a particular problem.

| Define | Identifies the problem | Late deliveries |
| Measure | Collects process data | Delivery time analysis |
| Analyse | Finds the root cause | Identifies approval delays |
| Improve | Creates better solutions | Remove unnecessary approvals |
| Control | Keep the improvements in place | Uses dashboards and KPIs |

Green Belt professionals can see the problem at its root and look deeper to find the real cause. This helps them fix the problem before they become costly mistakes. It is a necessary step to stop the same problem from happening again and again. This helps businesses save money over time and deliver better results.
