What are some common UX Design and Problem solving frameworks/checklists?

Are there any standard checklists or frameworks for UX Problem Solving?

EDIT: I realize there's no one-size fits all, but looking for a starting point. Might not do all of the steps, but might prevent missing a step.

In Technical troubleshooting there is the standard TroubleShooting method I learned in the military, similar to the Scientific Method

1. Identify the Symptom
2. Confirm/Reproduce the Symptom
3. Identify possible Causes (in software this would be breaking the program down into pieces/components)
4. Test each possible cause to rule it out
5. Once we confirm the component that is causing the problem, try to break it down further.
6. Fix problem
7. confirm fix by repeating Step 2.
8. Document solution if it's likely to occur again.
