OSS/BSS and the eTOM

I have been reading version 7 of the Enhanced Telecom Operations Map. This is useful in business process specification, providing a reference model from which a particular enterprise and define segments in its process flows. For an existing enterprise, these can be derived by analysis of existing processes, or at least of existing situations where some informal activity exists ready to be structured into a controlled process.
Another possibility is defining process flows in a greenfield startup, where there is no situation to analyze. There are plans and business models, but these need to be validated from real market experience, and will undoubtedly change drastically. So what is needed is design-based process definition, rather than business process analysis. It needs to produce flexible processes, that can respond to feedback from the market.
Going back to the eTOM, this could fit in with the SIP process group (Strategy, Infrastructure, Product), particulary Product Life Cycle Management with emphasis on the customer relation and service level. Perhaps the supplier/partner level is also important, especially if distribution channels for service and goods are treated as partners.
