- Manage by fact and reduce variation
- Involve and equip process teams
- Undertake systematic improvement
The DMAIC Framework Explained
The DMAIC framework sits at Lean Six Sigma’s core and gives teams a well-laid-out way to solve problems. The framework has five phases:
- Define: Identify problems from company’s, stakeholder’s, and customer’s points of view
- Measure: Learn about current processes and gather performance data
- Analyze: Find root causes through data analysis
- Improve: Implement and verify solutions
- Control: Monitor improvements and prevent problem recurrence
This method works well in organizations of all sizes, whether they use it as a program initiative or build a complete system around it. It brings together Lean’s waste reduction and Six Sigma’s variation control to create a complete process improvement system.
