Competitive Advantage: Creating and Sustaining Superior Performance by What's the difference between value chains and supply chains?
A supply chain includes all the raw materials and parts that are made into a product and distributed up the chain for manufacture and sale. In contrast, a value chain ecompasses all the individual steps that are taken to create a marketabel product. That includes not only physical components but also various value-adding activities that might be classified as part of the "knowledge economy" - things such as innovation, design, marketing, and sales - and that lead to the development of a product ready for customers.
Many corporations describe their value chain on their website. Publicly traded companies usually offer more information than private ones. Begin by examining their investor documentation including US SEC 10K or 20F reports, ESG reports and other sources for value chain descriptions, models and analysis.
