Cracks on the jet engine is a closed-end problem. A typical problem solving process has 8 steps:
Step 1: Define the Problem
- What is the problem?
- How did you discover the problem?
- When did the problem start and how long has this problem been going on?
- Is there enough data available to contain the problem and prevent it from getting passed to the next process step? If yes, contain the problem.
Step 2: Clarify the Problem
- What data is available or needed to help clarify, or fully understand the problem?
- Is it a top priority to resolve the problem at this point in time?
- Are additional resources required to clarify the problem? If yes, elevate the problem to your leader to help locate the right resources and form a team.
- Consider a Lean Event (Do-it, Burst, RPI, Project).
- Ensure the problem is contained and does not get passed to the next process step.
Step 3: Define the Goals
- What is your end goal or desired future state?
- What will you accomplish if you fix this problem?
- What is the desired timeline for solving this problem?
Step 4: Identify Root Cause of the Problem
- Identify possible causes of the problem.
- Prioritize possible root causes of the problem.
- What information or data is there to validate the root cause?
Step 5: Develop Action Plan
- Generate a list of actions required to address the root cause and prevent problem from getting to others.
- Assign an owner and timeline to each action.
- Status actions to ensure completion.
Step 6: Execute Action Plan
- Implement action plan to address the root cause.
- Verify actions are completed.
Step 7: Evaluate the Results
- Monitor and Collect Data.
- Did you meet your goals defined in step 3? If not, repeate th 8-Step Process.
- Were there any unforeseen consequences?
- If problem is resolved, remove activities that were added previously to contain the problem.
Step 8: Continuously Improve
- Look for additional opportunities to implement solution.
- Ensure problem will not come back and communicate lessons learned.
- If needed, repeat the 8-Step Problem Solving Process to drive further improvements.
ANA has already known what is going on, the next step they should adopt is collecting more infor-mation on the problem. If the airline is hurry to the solution, it may choose 'Generate options ad-dressing the issue'. The crack on turbine blade can be welded, or the airline replaces a new blade. However, jumping to solution without knowing the root cause does not completely solve the prob-lem. The root cause is unaddressed, then it may occur in the future. Therefore, the airline should still collect information to find the root cause, then remove it.
