Define key performance indicators (KPIs) to measure success.
Establish a baseline for comparison during subsequent phases.

Analyze: Identifying Root Causes

Use statistical tools and techniques to analyze data.
Identify the root causes of defects or variations using methods like Fishbone diagrams or Pareto charts.
Prioritize issues based on their impact and occurrence.

Improve: Developing Solutions

Generate potential solutions through brainstorming sessions.
Evaluate and select the most effective solutions using statistical tools.
Implement changes, ensuring they are sustainable and measurable.

Control: Ensuring Long-Term Success

Establish controls to prevent recurrence of issues.
Monitor process performance post-implementation.
Continuously refine processes based on feedback and new insights.
