Your business plan serves as a sales tool to your financial backers, yourself, and even those who want to hire. In fact, by selling your business ideas and a profitable long-range plan, you can attract talented people who will be more inclined to stay for the long haul.
Be careful, however. Too much sales hype and the overuse of superlatives can be the downfall of an otherwise sound business plan. Wow your new hires with the business idea, not fancy buzz words.
