How often should the Integrated Defense Plan (IDP) be reviewed?

• A. 6 months
• B. 12 months
• C. 24 months
• D. Ongoing

Answer: (B)

The key idea is that the Integrated Defense Plan is a living document that must stay current with evolving threats, resources, and mission priorities. A formal review on a yearly cycle ensures the plan is refreshed to reflect new conditions, aligns with the annual budget and planning processes, and incorporates lessons from exercises and real-world events. Between reviews, updates can be made as needed, but a scheduled annual review provides a consistent, documented point to validate assumptions, reallocate resources, and update risk priorities. Frequent six-month reviews would be unnecessarily burdensome, while waiting two years risks outdated planning. Continuous updates help, but they don’t replace the value of a formal annual cadence.
