解説
問 37
Incorrectア
“Draw up a recovery plan that specifies recovery methods and other details” is the act of deciding goals and procedures in advance, so it belongs to P (Plan). At that point nothing has been executed or checked yet, so it is not Act.
Incorrectイ
“Conduct regular education and drills for personnel” is the act of actually operating and carrying out the plan that has been drawn up, so it belongs to D (Do). It is the stage of putting the plan into action, not a revision based on results.
Incorrectウ
“Carry out reviews and tests of the recovery plan's content to verify it” is the act of inspecting and evaluating whether the plan works as intended, so it belongs to C (Check). エ is the stage that takes those verification results and revises the plan, so what comes after ウ is Act.
- エ
正解 The correct answer is エ. In the PDCA cycle, A (Act) is the stage where you take the inspection and evaluation results obtained in C (Check) and make corrections and improvements for the next cycle. Option エ, “Based on the results of the reviews and tests, revise the recovery plan if necessary,” is exactly the action of feeding the deficiencies found in Check, and changes in the environment, back into the recovery plan, so it corresponds to Act. In IT service continuity management, the system configuration, sites, personnel, and assumed risks all change over time, so continually reflecting the issues revealed by drills and tests in the plan is the key to continual improvement.
ここがポイント
- How PDCA maps to actions: Plan = drawing up plans and procedures; Do = carrying them out as planned (including education and drills); Check = inspecting through reviews, tests, and audits; Act = correcting and revising the plan based on the inspection results. You can identify the stage just by seeing whether the verb in the option is “draw up / carry out / verify / revise.”
- IT service continuity management (service continuity management) is an activity for keeping the adverse impact on the business to a minimum when a disaster or similar event occurs. It does not stop at drawing up a recovery plan; it also covers continually improving the plan through drills and verification.
