Why Should A Company Understand Its Supply Chain?Mapping out a supply chain is one of the critical steps in performing an external analysis in a strategic planning process. The importance of clearly laying out the supply chain is that it helps a company define its own market and decide where it wants to be in the future. In developing corporate-level strategies, a company often needs to make decisions on whether to operate a single line of business or enter into other related or unrelated industries. Each stage of a supply chain is essentially a different industry, for example, raw material extraction and manufacturing. The supply chain enables a company to understand others that are involved in each of the stages, and therefore provides some insights on the attractiveness or competitiveness in these industries the company might want to enter in the future.
