How is SWOT analysis effective in supply chain?

SWOT analysis explore the internal environment (strengths and weaknesses) and the external environment (Opportunities and threats) throughout the competitive supply chain market....

I think SWOT analysis is a strategic necessity for supply chain and continuously assessment is needed not only to evaluate the factors affecting the business environment but also to adjust / re-adjust the direction of the business future.
