Marketing Plan is a planned implementation of marketing resources to achieve marketing objectives. This means, Marketing Plan is a systematic process in designing and marketing of marketing decisions. The marketing plan will focus on information gathering, information dissemination formats and the structure of development and coordinating the company's strategic and tactical responses.
Ideally, after writing marketing plans for a few years, you can sit back and review a series of them, year after year, and check the progress of your company. Of course, sometimes this is hard to make time for (;there is that annoying real world to deal with);, but it can provide an unparalleled objective view of what you've been doing with your business life over a number of years.
