Annotated Bibliography of appropriate sources for the business plan – at least 1

Annotated Bibliography of appropriate sources for the business plan – at least 10, of which at least five must be peer reviewed or similar. I am often told that it is hard to find peer reviewed sources for a business plan, but once students look a little harder, they can always identify some.
References should, for the most part, be recent (2016 or later), and all should be pertinent to the paper.
