Get a proven methodology to de-risk your deployment challenges with TCS’ Hosted OSS/BSS Professional Services.

TCS’ Hosted OSS/BSS Professional Services team has crafted an innovative approach best suited for Hosted OSS/BSS product deployment on the basis of a combination of standard methodologies and modified SDLC. TCS’ Hosted OSS/BSS Implementation Methodology is called UPAKARANA, with innovative implementation and three flavors varying in terms of scope and time to launch:

  •   DRUTA: Rapid deployment
  •   PURNA: Complete deployment
  •   NUTANA: New component deployment

Utilizing the core advantage of a pre-integrated platform with pre-modeled business processes and transactions, it is imperative that service providers maximize this out-of-the-box” solution. This necessitates an upfront Requirements / Adaptations phase.  

Product adaptations are essential for activities such as new component deployment and non-core customizations to ensure that the Hosted OSS/BSS Core Design Principles are appropriately imbibed and followed across the board to ensure uniformity in the implemented solution.  

One of the critical success factors in any deployment is the use of “proven migration methodologies” and hosted OSS/BSS incorporate a CDM approach at the heart of this critical activity.

The optimization of the time to launch is further served by operating the release cycle, configuration and testing phases in iterative / parallel streams, ensuring effective utilization of scarce customer resources in the most efficient manner.

Finally, a governance model that is best suited to the type of implementation with concrete executive support is a mandated need in our deployment model for ensuring success.


  • A customized implementation methodology is available in three flavors on the basis of the time to deploy and feature functionality. 
  • A CDM-based migration helps you with faster and accurate migration of source data onto the hosted OSS/BSS landscape. 
  • WYSIWYG: A demo-based Requirements Elicitation Process helps you with quicker and accurate requirements gathering and expectation setting.
  • A single code implementation strategy ensures minimal impacts during hosted OSS/BSS product upgrades.
