1. DEFINE PROBLEM
- Describe the current situation.
- Elaborate to make the problem specific.
- Use available information such as: documents, pictures, data practical examples.
- Question the effect: Why is it a problem?
- Determine the problem focus- Use Pareto Chart.
- Compile: Data & Facts.
2. FIND THE ROOT CAUSE
Five WHY Analysis
- Suitable for simple or linear problems.
Ask ‘WHY’ enough times to reach the true causes of the problem.
Cause & Effect Diagram
- Suitable for possible complex influences.
- To evaluate the entire problem landscape. Clarifying results & dependencies.
3. VERIFY THE SOLUTION
- Check the veracity of the solution, this is an important step.
- Verify that the countermeasures were successful; they have solved the problem & lead to the correct results.
- Use data & pictures- before /after, test records (tally charts etc.)
- If the actions do not achieve the desired results, go back to step 2 “Find root cause”.
4. SOLVE THE PROBLEM
- Consider probable causes that help the team to a permanent solution/countermeasure.
- Evaluate the solutions & ideas using cost-time diagram to evaluate benefits. Drive the team to focus on quickly converting the solutions to reality.
- Create the countermeasures implementation plan
- What actions, Who-responsible, When- time.
