• Develop a data collection plan for the process.
• Collect data from many sources to determine types of defects and metrics.
• Compare to customer survey results to determine shortfall.

Analyze:

• Analyze the data collected and process map to determine root causes of defects and opportunities for improvement.
• Identify gaps between current performance and goal performance
• Prioritize opportunities to improve.
• Identify sources of variation.

Improve:

• Improve the target process by designing creative solutions to fix and prevent problems.
• Create innovative solutions using technology and discipline.
• Develop and deploy implementation plan

Control:

• Control the improvements to keep the process on the new course.
