Plan of actions: consists in a very detailed description of the procedures and means to implement the actions we want to take. For example, if the strategy implies a raise in advertising volume, the plan of actions should establish where the advertisements will be placed, the dates and frequency of the advertising campaigns, a set of procedures to evaluate their effectiveness. The actions we plan to take must be clearly formulated, measurable, and the results must be monitored and evaluated.
Imagine if you can do all these and manage all these in a marketing plan? Systematic, organized, well thought, innovative and captured all your pertinent business information, don't you find having a marketing plan is useful for your business?
