A CustomerFacingServiceSpec defines the properties (attributes) common to a particular CustomerFacingService used to realize the associated Product(s). This entity serves as a common basis to build any set of CustomerFacingServices that the service provider needs.<br/><br/>The CustomerFacingServiceSpec represents all the Service Provider’s know-how of intangible goods at a functional level. It would be more appropriate to name it KonwHowSpec or ProductFacingServiceSpec, but the name is not changed as it is well known.<br/><br/>The ProductSpecification corresponds to a sub-set of the Service Provider’s know-how according to what marketing people want to sell. Therefore, a ProductSpecification is a restriction of CustomerFacingServiceSpecs.<br/>
