What is the last step of the cyclical problem-solving process? (APIE)

• A. Evaluation
• B. Plan
• C. Implement
• D. Analyze

Answer: (A)

Evaluating is the step that closes the cycle. After you implement controls or procedures, you review what happened by collecting data, comparing outcomes to the criteria you set during planning, and judging whether objectives were met and risk was reduced. This is where you determine effectiveness, identify gaps, and decide what to adjust or restart the cycle with new actions. In hazmat work, you’d look at actual results like exposure levels, safety performance, and any unintended effects, then use those findings to refine the plan or start the assessment again with new goals. The other phases fit earlier in the process: planning creates the actions to take, implementing carries them out, and analysis is part of understanding the data, but the final step that ties everything together and drives the next cycle is evaluation.
