Case Study

35% faster testing and 40% faster data provisioning transform telecommunications QA

UST’s automated testing solution accelerated critical update and new feature delivery timelines by 35% and improved software quality and operational efficiency at a global telecom company. Advanced dashboards and automation tools enhanced visibility, reducing defects and boosting decision-making.

OUR CLIENT

This global telecommunications provider offers wireless communications, internet connectivity, broadband, and entertainment services to millions of consumer and commercial customers around the world. The company is recognized for its robust network infrastructure and cutting-edge technologies, including 5G, IoT, cloud services, and enterprise communication tools. Innovation, customer satisfaction, and sustainability are central to its mission.

THE CHALLENGE

Inefficient manual testing and limited visibility caused delays and defects

The company’s reliance on manual testing cycles caused significant delays and schedule slippage in its software development process. This inefficient approach increased employee workloads. Meanwhile, inadequate test coverage allowed defects to reach production, negatively impacting user experiences. Furthermore, limited visibility into testing progress and defect resolution hindered the development team’s ability to track performance and address bottlenecks efficiently.

Inconsistencies in testing practices across teams led to varied quality and inefficient resource utilization. The team’s limited understanding of the digital system architecture further hampered the company’s ability to design effective test cases. Managing complex test data across multiple business lines was challenging because of stringent business rules, causing delays in test-data provisioning. These issues resulted in increased costs, extended delivery timelines, and a higher risk of production environment system failures.

THE TRANSFORMATION

Implemented scalable, automated testing framework with early QA engagement and real-time insights

UST’s quality engineering solution transformed the telecom company’s testing operations, delivering faster, more reliable software releases while delivering comprehensive test coverage across critical applications.

By adopting advanced automations and real-time monitoring tools, the company improved operational efficiency, reduced costs, and enhanced customer satisfaction. An extensive knowledge repository helped the testing team continually improve its understand of the digital system architecture, boosting productivity and institutional knowledge.

With UST's quality engineering solution in place—including test data management, test management, test automation, system integration testing, and performance testing—the company can now proactively identify and address defects early in the development cycle, significantly reducing production issues. Early quality assurance (QA) engagement and defect prevention techniques were introduced, significantly reducing rework and improving software quality.

A business process testing (BPT) approach was implemented, covering functional, regression, acceptance, and API layers for thorough test coverage. UST adopted test-driven development (TDD) methodologies to modernize digital system testing, with a focus on customer experience, omnichannel, and mobile testing. A CI/CD-compatible test automation framework integrated with Jenkins enabled continuous testing and automated health checks.

UST enhanced test management with a custom quantitative test process management (QTPM) dashboard, offering real-time insights into testing progress and defect resolution. Test data management (TDM), powered by Datamaker, streamlined test data creation and maintenance, ensuring compliance with business rules.

THE IMPACT

Faster testing and data provisioning boosted quality and efficiency

UST’s solutions helped reduce testing cycle times by 35%, accelerating the client’s time-to-market for critical updates and new features. Automated business process test automation significantly reduced manual effort, achieving substantial cost savings. Optimized QA processes reduced production defect leakage, enhancing application stability and improving user experiences.

Post-release defects were minimized, lowering rework costs and increasing customer satisfaction. TDM reduced test data provisioning turnaround time by 40%, enabling faster and more efficient continuous testing. The QTPM dashboards provided real-time insights, improving decision-making and enabling proactive risk mitigation.

Streamlined defect management, supported by JIRA, improved collaboration and prioritization between development and testing teams. Overall, UST’s scalable and efficient testing framework helped the client align IT operations with evolving business needs, achieving greater scalability, cost efficiency, and improved software delivery timelines.
