Value Chain Analysis
In order to better understand the activities leading to a competitive advantage, one can begin with the generic value chain and then identify the relevant firm-specific activities. Process flows can be mapped, and these flows used to isolate the individual value-creating activities.
Once the discrete activities are defined, linkages between activities should be identified. A linkage exists if the performance or cost of one activity affects that of another. Competitive advantage may be obtained by optimizing and coordinating linked activities.
The value chain also is useful in outsourcing decisions. Understanding the linkages between activities can lead to more optimal make-or-buy decisions that can result in either a cost advantage or a differentiation advantage.
The Value System
The firm's value chain links to the value chains of upstream suppliers and downstream buyers. The result is a larger stream of activities known as the value system. The development of a competitive advantage depends not only on the firm-specific value chain, but also on the value system of which the firm is a part.
Creating a cost advantage based on the value chain
A firm may create a cost advantage:
* by reducing the cost of individual value chain activities, or
* by reconfiguring the value chain
