Top 10 Business Plan Mistakes

6. The plan makes unfounded or unrealistic assumptions. By their very nature, business plans are full of assumptions. The most important assumption, of course, is that your business will succeed! The best business plans highlight critical assumptions and provide some sort of rationalization for them. The worst business plans bury assumptions throughout the plan so no one can tell where the assumptions end and the facts begin. Market size, acceptable pricing, customer purchasing behavior, time to commercialization -- these all involve assumptions. Wherever possible, make sure you check your assumptions against benchmarks from the same industry, a similar industry or some other acceptable standard. Tie your assumptions to facts.

A simple example of this would be the real estate section of your plan. Every company eventually needs some sort of real estate, whether it's office space, industrial space or retail space. You should research the locations and costs for real estate in your area, and make a careful estimate of how much space you'll actually need before presenting your plan to any investors or lenders.

7. The plan includes inadequate research. Just as it's important to tie your assumptions to facts, it's equally important to make sure your facts are, well, facts. Learn everything you can about your business and your industry -- customer purchasing habits, motivations and fears; competitor positioning, size and market share; and overall market trends. You don't want to get bogged down by the facts, but you should have some numbers, charts and statistics to back up any assumptions or projections you make. Well-prepared investors will check your numbers against industry data or third party studies -- if your numbers don't jibe with their numbers, your plan probably won't get funded.

8. You claim there's no risk involved in your new venture. Any sensible investor understands there's really no such thing as a "no risk" business. There are always risks. You must understand them before presenting your plan to investors or lenders. Since a business plan is more of a marketing tool than anything else, I'd recommend minimizing the discussion of risks in your plan. If you do mention any risks, be sure to emphasize how you'll minimize or mitigate them. And be well prepared for questions about risks in later discussions with investors.

9. You claim you have no competition. It's absolutely amazing how many potential business owners include this statement in their business plans: "We have no competition."

If that's what you think, you couldn't be further from the truth. Every successful business has competitors, both direct and indirect. You should plan for stiff competition from the beginning. If you can't find any direct competitors today, try to imagine how the marketplace might look once you're successful. Identify ways you can compete, and accentuate your competitive advantages in the business plan.

10. The business plan is really no plan at all. A good business plan presents an overview of the business -- now, in the short term, and in the long term. However, it doesn't just describe what the business looks like at each of those stages; it also describes how you'll get from one stage to the next. In other words, the plan provides a "roadmap" for the business, a roadmap that should be as specific as possible. It should contain definite milestones -- major targets that have real meaning for your business. For instance, reasonable milestones might be "signing the 100th client" or "producing 10,000 units of product." The business plan should also outline all the major steps you need to complete to reach each milestone.

Smoothing Out the Rough Spots

Once you know what mistakes not to make, there are still a few steps you need to take to make your business plan "bulletproof." Be sure you:

Think it through. You might have a great idea, but have you carefully mapped out all the steps you'll need to take to make the business a reality? Think about building your management team, hiring salespeople, setting up operations, getting your first customer, protecting yourself from lawsuits, outmaneuvering your competition, and so on. Think about cash flow and what measures you can take to minimize your expenses and maximize your revenue.
