Planning involves setting goals and developing plans at three levels - strategic, tactical, and operational. Strategic goals and plans are for the long-term direction of the organization as a whole, tactical goals and plans are for major divisions and departments, and operational goals and plans specify actions for individual work groups and tasks. Effective goals are specific, measurable, time-bound, achievable, and important. Barriers to planning like resistance to change can be overcome with communication, participation, and consistency.
