Performance measurement: constitutes the last but not the less important stage of the marketing plan, since we can achieve only what we can measure. In order to measure the performances achieved through the marketing plan, we need to constantly monitor each previous stage of the plan.
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.
