OSS/BSS architecture

Structure and evolve an operator’s systems: CRM, catalogue, provisioning, mediation, billing, and the legacy applications that connect them.

The challenge

At an operator, OSS/BSS is where things get complicated. Dozens of applications, often from several generations, critical interfaces and flows that directly affect revenue. Our consultants have worked there for more than fifteen years, across fixed, mobile and fibre.

What we often see

  • Launching a new offer takes months, because the catalogue is duplicated across several systems
  • Legacy applications that nobody dares to change any more
  • A BSS migration or major upgrade that worries everyone
  • Gaps between what is activated on the network and what is billed

Our approach

  1. 1

    Map the chain

    Applications, flows, reference data and responsibilities, from CRM to billing, with weak points identified.

  2. 2

    Define the target

    A structure aligned with TM Forum frameworks (eTOM, SID, ODA) where they help, and adapted to your constraints where they fall short.

  3. 3

    Modernise in steps

    Wrap the legacy, move functions one at a time and keep a way back at every stage.

  4. 4

    Keep it consistent

    A cross-cutting solution architect role that arbitrates between teams and vendors throughout the programme.
