ITWORX Conducts Full End-to-End Testing of Bakcell’s New BSS Provided by Huawei NGBSS

Customer Profile

Bakcell is one of the leading mobile operators in Azerbaijan with subscribers base of 3 million subscribers and growing. The company was established in 1994 and became the first to provide state-of-the-art mobile communication services in Azerbaijan.

The Challenge

As part of its Billing Transformation Program, Bakcell was planning a crucial change of their operators, revamping their whole system to a new Huawei system. They wanted to avoid any interruption or dysfunction in the normal operations of different business departments during this transformation.

The Solution

Based on ITWORX’s solid experience in testing different Telecoms systems, the ITWORX team reviewed all the requirements and test cases, in addition to creating new test cases that were not included in the initial test book, to ensure that the systems were thoroughly tested against all possible scenarios. The new BSS includes different modules such as Customer Relation Management (CRM), Convergent Billing Solution (CBS), Electronic Voucher Center (EVC) and Universal Voucher Center (UVC), IP Contact Center (IPCC), Mediation and Provisioning. ITWORX provided two teams of Telecoms professionals— offshore and onsite teams. The offshore team executed all the back-end test cases and scenarios that don’t mandate direct interface with Huawei nor Bakcell. Whereas the onsite team was responsible for the execution of test cases that require onsite presence, in addition to day-to-day direct communication with Huawei, Bakcell IT, as well as all Bakcell business departments. The collaboration of both teams was essential to guarantee the best testing results with optimum cost. The testing process went through different phases starting from the primary UAT, Configuration and Setup Data Verification, Tariff Testing, and Cycles of Regression. The ITWORX team coordinated closely with Huawei and other stakeholders, not only to ensure a successful Go-Live, but also to limit potential cost exposure to Bakcell through the “Testing Factory” Concept.

The Benefits

Smooth transformation from legacy BSS to the new ones without causing dysfunction throughout the operation processes § Availability of highly experienced Telecom professionals guaranteed covering all possible E2E scenarios across the entire Huawei NGBSS § Keeping the necessary balance between the business & technical objectives without making any risky trade-offs

“Since starting the engagement, ITWORX team showed excellent performance, trapping most of the defects before the business users get to test the platform. ITWORX team has shown tremendous skill, professionalism, dedication and a great attitude towards this project and throughout their work. I have only heard good things from my project team about ITWORX’s performance.” Hamid Husain, Chief Information Officer

When Zain-Iraq recently replaced their Business Support Systems (BSS) with new Huawei solutions, they needed complete end-to-end User Acceptance Testing (UAT) of the customer care and billing system (Huawei NGBSS).
Some work had already been done, and time was now of the essence. The Ericsson project team therefore, looked for a highly professional partner, experienced in the Telecoms industry, to perform the testing, and to lead the handover to various business departments.
ITWORX was selected. We not only achieved the timeline, we also delivered a smooth transition and a superior testing service – one that got business users involved and familiarized with the new systems. The result fully met – and even exceeded – Ericsson and Zain-Iraq’s expectations.

The Challenge

As well as a time critical process, Zain-Iraq also wanted to avoid any interruption or dysfunction in the normal operations of all business departments during the testing and transition to the new Huawei-based system.

This was particularly important as the new BSS included numerous modules, such as:

  • Customer Relation Management (CRM)
  • Convergent Billing Solution (CBS)
  • Electronic Voucher Center (EVC) and Universal Voucher Center (UVC)
  • IP Contact Center (IPCC)
  • Mediation
  • Provisioning

The Solution

Based on our solid experience in testing different Telecoms systems, the ITWORX team reviewed all the requirements and test cases. We also created new test cases, not included in the initial test book, in order to thoroughly investigate all possible scenarios.

We provided an offshore team of Telecoms professionals. This team carried out all the test cases, including the back-end scenarios, and only required a minimal level of onsite support. In addition, we ensured direct communication with Huawei and Ericsson on a day-to-day basis.

Formal reviews were set in place for each activity the testing team performed, to ensure it was implemented as per the plan, and met the requirements specified in the FRS.

The scope of testing included:

  • Test planning
  • Detailed timeline for each activity in the test cycle
  • Test preparation
  • Test case design
  • Test case preparation
  • Test data preparation
  • Test execution
  • Regression testing
  • Integration testing
  • System testing
  • Co-ordination with the onsite team
  • Defect management and reporting
  • Status reporting
  • Daily and weekly status updates

The Benefits

Our solution delivered a smooth transformation from the legacy BSS to the new one, without causing any dysfunction.

This was a superior testing service, which achieved the business objectives using an optimal technical approach without making any risky trade-offs.

The fact our team consisted of highly experienced Telecoms professionals ensured all possible end-to-end scenarios could be covered.
