What is Value Chain Analysis? Definition, Model & Example

What is value chain analysis and how to use it? This article will show you the definition, model, and the example.

What is Value Chain Analysis?
"It can be defined as a strategic planning tool and it's used to analyze the value chain of the focal company. Value chain is how internal functions create value for customers. Value system is the way each value chain is structured and it spans across multiple companies"

What is the Value Chain Model?
Value Chain Model is mentioned extensively in the first half of the book "Competitive Advantage" in 1985 by Michael E. Porter. The Value Chain Model represents various functions under "one" company and how they should work together to create "Competitive Advantage".

Value Chain Model


What is the Competitive Advantage?
Competitive Advantage is the ability for a firm to put "generic strategy" into practice, the generic strategy includes,

Cost Leadership: aiming to offer the lowest price to customers

Differentiation: selecting the important attributes that buyers want so the company can get a premium price

Focus: doing each strategy according to each market segment

What is Value System?
Another related concept is "Value System", it's simply how each value chain (company) is connected with each other.

What is NOT Value Chain Analysis?
We know for the fact that many people, ranging from practitioners in academia, don't really understand this concept. Then we conduct a quick literature review in this area. Convenient sampling has been carried out to determine the current practice, 20 scholarly articles available via Google Scholar are examined and the results are as below,

What is not VCA?

The results are surprisingly shocking! Only 9 out of 20 articles cite Porter as the source of the concept (only 3 of them explain the concept appropriately, the rest of them do a value system analysis using the unknown methodology). Five articles (mainly from an economic perspective) mistakenly use the term to present an unrelated concept called "Global Commodity Chain" by  Gereffi, G. and Korzeniewicz, G. (Ed) (1994) Commodity Chains and Global Capitalism.

The surprise doesn't end there, 5 articles present the concept without citing any source, it seems they invented their own methodology. One paper cites many lean manufacturing articles instead of Porter's so conclusion can be drawn that it's Value Stream Mapping.

What are some examples?
According to a literature review, articles related to this concept are extremely unreliable. Then, Original Porter's Competitive Advantage is used as a source.

1. Defining Value Chain: Identify business units/products, determine key functions and include all relevant activities of each function

2. Capturing Cost Data: Estimate costs and assign them to various activities in your value chain. Then, select stronger competitors and determine how they allocate costs to each activity and why.

According to Porter, the cost analysis part doesn't need to be very precise, just the estimate is OK. But, a company needs to compare its cost profile against its competitors to reveal the competitor's strategy.

3. Controlling Costs: Find cost drivers and control them such as,

- Scale: expand product lines/facilities
- Linkage: control supplier scheduling, the location of warehouse, payment policies
- Timing: Wait until the technology is getting less expensive than acquire them
- Investment: focus on technology that cut costs
- Procurement: reduce SKUs, the supply base for better volume

4. Cutting Buyer's Cost: Follow these simple guidelines,

- Lower setup cost/time
- Decrease financing cost
- Improve quality/reduce inspection
- Reduce required maintenance
- Speed up processing time
- Reduce required monitoring/control

5. Determining Purchasing Criteria: Try to figure out the key criteria and try to provide favorable delivery timing or improve product features, packaging and appearance or improve after sales/service

6. Reconfiguring Value Chain: Change the way each activity is performed to support the strategy
