But, before we continue, we must understand and accept that steps of the marketing plan are universal. It is a logical approach of the planning activity, no matter where we apply it. The differences you meet from a plan to another consist in the degree of formality accorded to each phase, depending on the size and nature of the organization involved. For example, a small and not diversified company would adopt less formal procedures, because the managers in these cases have more experience and functional knowledge than the subordinates, and they are able to achieve direct control upon most factors. On the other hand, in a company with diversified activity, it is less likely that top managers have functional information in a higher degree than the subordinate managers. Therefore, the planning process must be formulated to ensure a strict discipline for everyone involved in the decisional chain.
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?
