Define: Clearly articulate the project’s goal and scope, identifying the problem or opportunity for enhancement.
Measure: Collect and analyze relevant data to understand the current state of the process and establish benchmarks.
Analyze: Utilize statistical tools to identify root causes of defects and variations, pinpointing areas for improvement.
Improve: Implement changes based on analysis, testing solutions, and optimizing processes.
Control: Establish mechanisms to sustain improvements, monitor performance, and prevent regressions.
