From the customer’s perspective, value consists of 2 basic elements: utility (fitness for purpose) and warranty (fitness for use).
Utility of a Service is perceived by the customer as an improvement in performance of tasks. Removal of constraints on performance is also perceived as a positive effect. That is: Fitness for purpose!
Warranty of a Service is derived from the positive effect being available, with sufficient capacity AND dependable in terms of continuity and security. That is fitness for use!
Illustrate a service (may not be IT related) you can offer using the concept of utility and warranty.
