Final answer:
The statement that a business plan should be written by the entrepreneur to maintain objectivity is false; it is often beneficial to involve external advisors for an unbiased perspective.
Step-by-step explanation:
To answer the question of whether it is true or false that to maintain objectivity, the business plan should be written by the entrepreneur, the statement is: False. Although business plans are often written by entrepreneurs themselves, it can be argued that involving a team that includes external advisors or consultants can help in maintaining objectivity and provide multiple perspectives. Entrepreneurship involves a deep personal connection to the business, and sometimes this can create bias which may affect the objectivity of the business plan. A business plan is a tool for communicating a company's strategy and vision to potential investors and partners, and therefore, it should present a balanced and realistic view of the business prospects.
Rewritten statement: To maintain objectivity, a business plan can be written by the entrepreneur but should also involve contributions from external advisors or consultants to ensure a comprehensive and unbiased view.
