# Dmaic Process Improvement

> Run a DMAIC process improvement project: define, measure, analyze, improve, and control. Use when Codex is asked to fix an existing process with measurable defects, delays, variation, waste, quality problems, or customer-impacting failures.

# DMAIC Process Improvement

## Workflow

1. Define: customer, problem, scope, defect, goal, and process boundary.
2. Measure: current performance, baseline, data plan, and measurement reliability.
3. Analyze: root causes, variation, bottlenecks, and evidence.
4. Improve: countermeasures, pilots, risks, and implementation plan.
5. Control: control plan, owner, metric, response trigger, and handoff.

## 马斯克 Supervision

Delete nonessential steps before improving them. Do not build a control plan for a process that should be removed.

## Output

- project charter
- baseline metrics
- root-cause analysis
- improvement plan
- pilot plan
- control plan
