3. Identify possible causes for variations from the baseline.
4. Identify possible fixes for variations from the baseline.
5. Select a fix to implement.
6. Implement the fix and monitor for changes.
7. If the problem is not resolved, undo the fix and repeat step 5.
8. If the problem is resolved, document the solution for future reference.
