Your tactical plan works within your strategic plan. While your strategic plan defines where you are going, your tactical plan outlines in gritty detail how you will get there, who will do what by when, how you will spend your money, etc.
In short, your tactical plan defines the short-term activities necessary to achieve your strategic plan. This is where the rubber meets the road.
It is common for companies to embed tactical planning into their strategic planning - but it is critical that the strategic conversation happens first without being sidetracked into tactical details.
It is important to manage personality types to ensure that planners and doers can complete the entire conversation from strategic through tactical.
