During which of the project lifecycle phases should deployment activities be added to the plan?

AgilePM’s lifecycle comprises Pre-Project, Feasibility, Foundations, Evolutionary Development (Development), Deployment, and Post-Project. Deployment is executed in the Deployment phase, but AgilePM expects deployment planning to be identified early and progressively elaborated as part of ongoing planning during Evolutionary Development. As timeboxes deliver verified increments, the team refines release content, readiness activities, and transition tasks (training, data migration, cutover, support). Embedding deployment activities into the plans during Development ensures that release preparation progresses continuously—not as a late-stage bolt-on—supporting predictable cadence and benefits enablement. While Foundations establishes the initial approach and high-level plans, the detailed, actionable deployment tasks and their scheduling are added and maintained within the Development phase planning cycles so the upcoming Deployment phase can execute smoothly. Hence, from the options provided, the correct choice is Development phase.
