Answer:
due diligence
Step-by-step explanation:
Due diligence refers to an entrepreneur or a business man/woman basically doing their homework, i.e. investigating thoroughly about a business opportunity before deciding to accept a business proposal, enter a new market, or start a new business.
Many times, management is required by law to perform due diligence before entering a new business or signing certain contracts, but it is just common sense that before you start a new business you will try to find out if the business is feasible or not.
