Tajul,
Your 1st question:
We worked on similar mapping. A great starting point was to use the GB929F, which list Domains, Applications and Functions in an Excel format. You can start mapping Applications or functions to BSS/OSS terms. to help with the mapping, you need to understand the functions, which are defined in the TAM documentation (GB929D)
As recommended by others, you should probably start adopting ODA and map your TAM functions to ODA blocks.
in the ODA project, TMF has started to map TAM functions to ODA components. It's very early stage, they have mapped 2 components to ODF assets (TAM, SID, ETOM OAPI).
Example.
I have a suggestion that could work: reverse engineers ODA to TAM mapping using ETOM/SID.
GB1022 has a list of ETOM processes and SID entities with ODA blocks. If you find a mapping between TAM and ETOM/SID (that should exist, right?), you have a decent (albeit imperfect) mapping between TAM and ODA blocks. And ODA blocks are easily mapped to BSS/OSS as suggested by previous posts in this thread.
Your 2nd question:
disclaimer: these are my personal opinionsI don't think a single vendor could deliver all BSS functions, maybe "on paper" but vendors support of a given function can vary from poor to great. Focus on the functions you need, not all of them.
- TMF has a member directory. Unfortunately, It doesn't say if the member is a CSP, a vendor or an academic institution.
There are also "BSS" vendors who declare to use TMF standards but are not members of TMF.
- You could contact your TMF account manager, maybe TMF can help you.
- for pure telecom BSS/OSS functions I would recommend that you favour vendors that have:
- signed the ODA/Open API manifesto
- adopted TMF standards (ODF, e.g. ETOM, SID OAPI's...)
- have as many TMF-certified Open APIs as possible
If your company starts a BSS transformation programme, adopting ODA now could bear great benefits in the future. With ODA and Open API's you have the privilege of not being locked to a vendor.
EDIT: I see some great potential in using the
TMF component template to be a great tool for comparing and selecting a vendor.
My 2 cents!

Subject: BSS and OSS mapping in TAM Framework
Hi,
1) Is TM Forum officially defined which functional blocks in TAM framework are BSS and OSS? Basically, I would like to know the demarcation between OSS and BSS in terms of the functionalities.
2) If the mapping is available, is there any solutions which can deliver all the BSS functionalities? Or we need to choose best of breed approach to implement the functionalities?
