In the old days, marketing used to be simpler. A person needed something and you created it and created it in such a quantity that it fulfilled the needs of everyone and you get the profit. Be it shoes, rice, clothes, food, tools, or anything that satisfied the need of a person, there were people to create it and earn profit from this creation.
However, marketing these days has changed significantly. Not only do you have to keep track of all the variables, but you also need to be on the top of the list of the direct and potential competitors you have that fulfill the same need as your products do. The method with which you plan, organize, lead, and control the market in such a way that you are the best among your competitors all while keeping your profits at a maximum and the costs at a minimum is called strategic marketing or strategic marketing management.
