While there isn't a universally agreed-upon set of "four" problem-solving steps, a commonly used and effective framework is the four-step problem-solving model:

1. Define the Problem: Clearly identify the issue. What needs to be solved? What are the symptoms? What are the potential causes?

2. Generate Solutions: Brainstorm various possible solutions. Don't limit yourself initially; the goal is to come up with as many ideas as possible.

3. Evaluate Solutions: Analyze the pros and cons of each solution. Consider feasibility, cost, effectiveness, and potential risks.

4. Select and Implement a Solution: Choose the best solution based on your evaluation and put it into action. Monitor the results and make adjustments as needed.

This framework is adaptable to various situations, and you can add more specific steps as needed. For example, you might include a step for gathering information or a step for reflecting on the outcome.
