A business plan is an important tool for a business of any size. It contains the aims and objectives of the business as well as the supposed means of achieving them. It equally guides the management against derailing from the initial vision of the business.
To write an effective business plan, you must keep the following points in mind:

1. WRITE WITH YOUR AUDIENCE IN MIND
The starting point to writing an effective business plan is to write from the audience perspective. That is to identify who you are preparing the document for and your aim of doing so.
This is because if you are preparing the plan to secure funding from investors, the format should be different from when you are writing the plan to just serve as a guide to running the business.
For instance, a potential investor will be more interested in seeing detailed explanation on how you intend to make returns on his investment and the time frame.

2. DETAILED EXECUTIVE SUMMARY
This is perhaps the most important component of a business plan. It is written at the end of the planning process but presented as an abstract at the beginning of a business plan.
