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.
Pricing _ I once said in my Marketing Plan Breakthrough S6PEC that, "Price is the key determinants of your profits". I stand firm to keep it that way. In your marketing plan, you will address pricing plan for your distributors, customers, multiple segments (some business charge differently _ price discrimination) and cost price i.e. your raw materials and things like that. Not many address price correctly and bear in my mind that we need to standby few pricing plan to respond to the market. Take for example during festive season, if everyone is lowering price and slashed their price or even ignited a price war, what do you do about that? Follow suit or wait? If you want to follow, how far? If you want to wait, how long? You capture all this in pricing plan.
