Hi,
I’m working
for incumbent telecom operator. Our OSS and BSS
applications are spanned over many organizational units. Now we are trying to
conduct survey on our complete OSS/BSS domain. The goal is to eliminate
duplicated functionalities, identify missing applications and required
connections between isolated applications and to define one common strategy for
further development. We agree that we should follow TMF NGOSS recommendations. Now
we have dilemma on how to complete this task.
One way is
to identify our business processes and compare them with eTOM. We are aware
that this approach is probably better one but if we drill down to Layer 3
processes and compare them, it will need a lot of time and a
lot of people involved until we get some useful results.
The other
approach is to start with TAM and compare existing application functionalities
and contracts with TAM description. But the problem is immaturity of TAM.
Mapping between TAM and other frameworks (SID and eTOM) are not well defined
yet.
Can anyone
help on this? Which way is better?
