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.
Business Plan Analytics Through Key Performance Indicators (KPI's): Identifying key performance indicators for your business to use as benchmarks throughout the year is perhaps the most critical step you can make with regard to business analytics. Not only will KPI's help identify key shortfalls in the plan, but will help narrow your focus in addressing the shortfalls. For instance, recognizing that you have an issue in labor isn't merely enough when you consider the following possibilities: a) labor rates may be too high; b) overtime has exceeded its budget; c) the issue is regionally_based, not across the board; d) man hours may have exceeded its allocated budget, etc. It could be a myriad of triggers that caused labor to exceed its budget and KPI's enable you to drill down to the cause. KPI management requires a disciplined review process established monthly that fosters a blended analysis throughout the year that compares actual results against both budgets and forecasts.
