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.
Generally, companies are broken down into four levels of hierarchy, the corporate, the division, the business unit and the product level. The overall plan of the company is designed at a corporate level. As part of this planning, each resource is allocated to each division of the company. Next, division level planning allocates resources to each business unit of the company. In addition, business unit planning designs a strategic plan for each business area, which determines each of the marketing objectives/goals, strategies and tactics, that have to be consistent with the overall strategic plan.
