3-22. Transitions mark a change of focus between phases or between the ongoing operation and execution of a branch or sequel. The shift in relative priority between the elements of decisive action—such as from an offense to stability—also involves a transition. Transitions require planning and preparation well before their execution. The staff identifies potential transitions during planning and accounts for them throughout execution; assessment ensures that the staff measures progress toward such transitions and takes appropriate actions to prepare for and execute them. In a stability context, operations can involve multiple types of transitions, and they often occur concurrently. Stability operations include transitions of authority and control among military forces, civilian agencies and organizations, and host nations.
