A business idea is a short and precise description of the basic operation of an intended business. Before you start a business, you need to have a clear idea of the sort of business you want to run.
Your business idea will tell you.
WHICH need will your business fulfill for the customers and what kind of customers will you attract?
WHAT goods or services will your business sell?
WHO will your business sell to?
HOW is your business going to sell its goods and service?
HOW MUCH will your business depend upon and impart the environment?
A good business idea will be compatible with the sustainable use of natural resources and will respect the social and natural environment on which it depends.
