A business plan should be detailed. In listing your products and services for example, you should not really stop by just enumerating them. You also should write down the descriptions and scope of your products and services, touch base on production and identify means on how you can market your "brain - child" to your targeted niche.
Management & Planning Tool : If you are like many other small business owners, you are not only the owner of the company, you are likely also actively involved in the day-to-day operations as the President/CEO, the marketing department, the IT department, the HR department...the list goes on and on! One of the most important things to remember in trying to bring all of this together into a cohesive and efficient package is that planning is vital!
It should include a market research that identifies your competitors, their share of the market and the range of the products they produce. By learning how they conduct their operations, you may learn tricks of the trade in the business you want to enter and you also get to have a basis on what you can do to excel.
It also needs to be written in formal format and style. You have to remember that a business plan is something that you may have to present to your business partners, financial firms and banks. So if you can, refrain from using slang in any part of your plan.
