Sometimes people use the term business plan when they are referring to a project. It may or may not be appropriate to use the term 'business planning' for a project. Some projects are very substantial and equate to an autonomous (independent) business activity, in which case a business plan is entirely appropriate. Other projects are smaller, perhaps limited to internal change or development, and are less likely to require a conventional business plan, and are quite adequately planned and managed via project management methods.
