First you would determine what you would like your salary to be. You've dreamed about having a nice income to support your dreams I'm sure. Let's say right now you only make what your profit is giving you which might not be much. So let's say the first year, next year, you would love to have a consistent monthly salary of Ŭꯠ a month, every month. And every year you would like to be able to increase it so that after 10 years it would be at บꯠ per month. And let's say you would like to grow your business 10% each year.
I mentioned the financial aspect of a plan earlier, so let me add this. Another fact about financials to consider: not all business activities are about making money. Point being, in most enterprises financial considerations are centric to the document. But there are some other considerations. For example, a few years ago I wrote a plan for a new subsidiary that was focused on developing an inventory of patents. The potential financial returns were years into the future. Those patents may or may not ever have commercial value. Another example is a non_profit enterprise that has need for a complete roadmap for growing their profile in a market, of which a marketing plan would be the centerpiece.
