When you sit down to compile all of the elements of your business plan, make sure you have each section able to stand on its own merits. This means you should not reference other sections sending the reader (your potential investor) back and forth between sections.
Basically, consumers are hunkering down to limit spending, save money, conserve resources, and change the way they've been living. The major influence on the health of an economy is the psychological state of its consumers. When there exists a broad belief that spending beyond necessity is unwise, people will change their habits and as a result, some businesses will have to close their doors. The economy is molting into a new, leaner animal. Rather than react in desperation to avoid doom, firms should interact with the current situation with innovative and forward thinking actions.
If an online business, you need to go into detail how you will attract customers to your website. General statements like "I will use Face Book ads and email marketing" will contribute almost nothing to helping your cause unless you have detailed statistical analysis of tests you have conducted or of another similar business you have been associated with. If you do not have any data upon which you reference your estimates, it could show lack of proper thought to the remainder of your business plan.
The three basic actions for growing a business in any economic climate are: improve efficiency (maintain output while reducing inputs, such as time and money); increase volume (produce more in order to spread fixed costs); reorganize the business (change goals, methods and/or philosophy). If you plan to implement one of these, you may as well plan to implement them all. By focusing on one of the above strategies, you will find a ripple effect that causes a need to address the others. This is a good thing.
