  • 1.  How to define a CustomerFacingServieSpec in SID context

    Hi,

    I am new to TMF. I need some clarification regarding Information Modelling for service domain. How do we define a customer facing service specification?
    As per the information given in GB922_Service_v21.0.0, Product specifications are realized as CFSspecs, however when we go thru the examples in TMF633, it explains about 'Create service specification'; not CFS or RFS specification. So, I am a bit confused how we define CFSS and RFSS  specifically. I mean from a service specification how do I know if its a CFSS or RFSS or I am interpreting it all wrong.

    Hi Anubhav,

    I believe that there are many TMF assets that illustrate service catalogs with CFS and RFS specifications. I am specifically aware of IG1228 (https://www.tmforum.org/resources/standard/ig1228-how-to-use-oda-using-open-apis-to-realize-use-cases-v8-0-0/) to which my company contributes. But there are others.

    I believe that the distinction between CFS and RFS is a modeling choice for which best practices exist (e.g. IG1233).

    Best regards,

    Hi Roland,

    Thanks for your inputs. I still have one doubt. While defining a service specification in Service Catalog, how do we demark if its a CFS Spec or a RFS Spec? Is it the Category where we keep values as CFSS or RFSS or some other attribute where we keep this demarcation?

    Hi Anubhav,

    For me Customer Facing Services and Resource Facing Services are specializations of the Service entity. I mean, we use inheritance in our class model, which is 'flattened' in the API  by using the @baseType and the @type attributes, depending on how you model this. For instance, if you have a class model like this:

     

     If you want to send through an API and instance of the MobileLineCFS, the parameter mentioned above should have the next values:

     

    • @baseType = CustomerFacingService
    • @type = MobileLineCFS

    Of course, the same approach can be applied for service specifications, resources, resource specifications... and so no.

    Hope it helps.

    Best regards.
