Final answer:
The four stages involved in problem-solving are Planning, execution, evaluation, adjustment.
Step-by-step explanation:
Problem-solving involves four key stages. First, there's planning, where one defines the issue, sets goals, and devises a strategy. The second stage is execution, where the plan is put into action. Following this, there's evaluation, a crucial step to assess the results and determine if the initial goals were met. Finally, there's adjustment, involving modifications or refinements based on the evaluation. This iterative process ensures continuous improvement and adaptability. In summary, problem-solving progresses through planning, execution, evaluation, and adjustment, forming a dynamic and flexible framework for addressing challenges effectively.
