Plan
1Background
Why does this matter now? Link it to safety, quality, delivery, cost or people.
- Who is affected, and how?
- What happens if we do nothing?
2Current condition
Go and see. Describe what is really happening, with facts and data, not opinions.
- What, where, when, how often, how much?
- Sketch the process or add a simple chart.
3Goal / target
One clear, measurable target: what, how much, by when. The chart updates as you type.
4Root cause analysis
Ask “why?” until you reach a cause you can act on. Check each answer at the gemba. Blame the process, not people.
Do · Check · Act
5Countermeasures
For each root cause, what will we change? Prefer simple fixes that stop the cause coming back (error-proofing, standard work, visual controls).
6Implementation plan
Every action has one owner and a date. Review this list at the daily huddle.
| What | Who | When | Status |
|---|
7Check results
Did we hit the target? Show before and after with the same measure. If not, go back to step 4.
8Follow-up / standardise
Make the new way the standard way. Update standard work and training. Share it with other areas. Note anything still open.
