3. Designing a package of basic services

In reality, a service is a "bouquet of elementary services" that must be put together to best meet the customer's service values and functions, and the interests of the service provider. An elementary service is a kind of technical solution function, which appears within the service realization or preparation/production process.

Once these elementary services have been imagined, they need to be set against the service values and/or functions for the customer(s). A so-called service intensity matrix cross-references the values (here 1 to 7) with the proposed elementary services (here A to G) in a matrix that expresses the adequacy with qualitative evaluations such as {--, -, 0, +, ++}. The principle is that non-essential elementary services that are expensive and don't contribute significantly to all the values may well be discarded.
