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.
To make an effective plan, there is a famous rule called 4P's. Here, P's stand for Price, Product, Promotion and Placement. In this another P is added called People. Today while doing digital marketing or the traditional marketing one should understand people or the customers you are dealing with. It's important to figure out what is significant for the business, and later make a plan accordingly.
