Looking more closely at cost at each stage will identify drivers of cost that explain variation and will provide a source of competitive advantage. Looking more closely at profit at each stage will highlight the power of buyers. Competitive Advantage and the power of buyers are concepts are also identified by Porter as two of the five forces.
There is discussion that differentiates” value chain” and “value-added” concepts. The authors argue that “value chain” is better for investigation of strategic issues. They state that “value-added” begins too late because it misses the opportunity with suppliers and ends too soon due to the fact that opportunities with customers are missed. Additionally, an explanation is provided about the fact that a true value chain analysis shows that individual value activities are interdependent.

One would then have to ensure that any given stage in the value chain can be decoupled before proceeding. There may be difficulties with calculations but the authors firmly...
