Corrective Plan. A marketing plan is a living document. Trust me, the moment you have it and experience planning your marketing, you will realize this. Therefore it is a plan that allows you to assess past strategies and results and at the same time allow you to make necessary corrective measures to fit your business growth. for example, who expected the 2008 financial crisis to hit us so badly? No one other than the few so called "economists" but how did responded to it? Severely. Many businesses closed including many giants. But the good thing is, many have a solid marketing and business plans, therefore they make quick corrective actions and moved forward.
Establishing strategies: several strategies are to be formulated, in order to cover the distance between what we want to achieve and what is possible to achieve, with the resources at our disposal. As we would usually have several options, we should analyze them and chose the one with more chances to achieve the marketing objectives.
