What is one of the main purposes of setting a business plan?

A primary purpose of setting a business plan is to anticipate resources. This involves identifying the essential resources needed for the enterprise to function effectively, such as financial resources, human capital, technology, and materials. Having a clear outline of these resources allows a business to strategize on how to acquire them, allocate them efficiently, and utilize them in pursuing the company's goals.

In contrast, predicting inflation rates focuses on external economic factors, which can be useful but is not a core objective of a business plan. Establishing a dress code is more related to workplace culture and internal policies rather than the strategic planning of a business. Creating a social media strategy might be a component of a marketing plan, but it does not encompass the broader picture of resource management and forecasting necessary for a business plan.
