In Wardley Maps there is a concept of value in the value chain.
It is important that the value is actually fleshed out when discussing a map. The typical scenario shown in a Value Chain map is that Utility is better than Product.
There is an argument to be made that the perceived value needs to be understood in relationship to the actual value.
For the purpose of this exercise, I'm going to use a standard anchor in Wardley Maps, power.
Power can be attained in a multitude of ways and there are multiple aspects of value related to power. I'm using specifically Utility Power (from the local electric company) and rooftop Solar as the example.
I will not get into the artificial mechanism of turning rooftop Solar into a "utility like" solution. I'll leave that up to the sales guy that comes around once a month...
The basic concept is:
- The value chain helps make a decision
- Use power from a Product perspective or from a Utility perspective (see figure 1)
Figure 1. What a Value Chain describes
This is the choice, the value chain helps make a decision, use power from a Product perspective or from a Utility perspective.
To make a choice, you have to know what value you desire. Where do you get "additional value" (Figure 2).
The value may be tied to specific capability or need.
Figure 2. Additional Value
When you consider Rooftop Solar Power generation, which is arguably a product (Figure 3) and power from the power Company which is a utility, they each have a specific purpose
Figure 3. Rooftop Solar vs Power Company
Because one is a product, the value may be enhanced by an external mechanism
- One Example, a battery in the garage
- Another Example, selling power back to a provider
The other is enhanced with an internal mechanism (you don't get the choice)
- An example: Utility Company creates a new generation station (or buys power from a new generation station)
Figure 4. Enhanced Value
With that as the definition, lets talk about the choices available:
Choice 1: Value Decision Utility (Figure 5)
Making a decision to go only with Utility Power is a value decision
Undesired Effect: monthly utility bill, infrequent but possible outages, brownouts
Figure 5. Using Power company only
Choice 2: Value Decision for Rooftop Solar (Figure 6)
Making a decision to go only with Rooftop Solar is a value decision
- Being able to eliminate a Utility Bill or going “off Grid”
Undesired Effect: Its possible to run out of stored power, Costly Installation
Figure 6. Rooftop Solar
Choice 3: Value Decision Both (Figure 7)
Making a decision to go with both Solar and Utility is a value decision
Undesired Effect: Power is more expensive

Conclusion:
It is important to understand the need and outcome
It is vital to understand the value desired
Choosing incorrectly has undesirable effects
