Case Study: National GSM Operator speeds billing system delivery with ScienceSoft project management

National GSM Operator - Customer Case Study

National GSM Operator, a national GSM operator with more than 5M subscribers, needed to upgrade its billing solution to streamline complex charging processes and add customer self-service options. The project had already stretched beyond the planned 2-year timeline because a third-party managed telecom IT vendor struggled to coordinate communication and development across the client team and multiple vendors.

ScienceSoft assigned a full-time project manager to work with the client’s development team and introduced a clearer release-planning process. ScienceSoft reduced the testing cycle from 4–6 weeks to 2 weeks, improved visibility across vendors, and helped the billing system launch within the agreed timelines, making it easier for National GSM Operator to introduce new tariff plans and services.
