What's more important, sales or profit? Profit is what generates your salary. You could actually make more profit with less sales. Less sales could actually be less work. The most important thing for a business is to make money. That's profit. Now some might say, I don't care so much about making a lot of money. I like the freedom of owning a business. Well that is probably true, but if you don't watch your profit, you might lose that freedom. It's always amazed me how most businesses, even very large ones, talk about how much their sales are. You hear comments like, that's a บꯠꯠ company. But what's a บꯠꯠ company if it has no profit. Now I do admit that 2% net profit of บꯠꯠ is a lot bigger than 2% of ũꯠꯠ but most likely the large one carries a lot more headaches too.
If a document needs to be developed that requires input from other disciplines_Finance, HR, Property & Facilities, Marketing, Procurement/Supply Chain_ then most likely you are looking at a team building effort to get the job done. In any event, don't look at the task as only as a roadmap that leads to a profitable product or enterprise. Business plans are a great way to build team buy_in, force a thorough review of options, define objectives, establish benchmarks to judge performance, and help arrive at a plan_of_action. Ultimately, it can lead to a Project Management approach to implementing a plan and that can be as involved and detailed as is necessary.
