Telecom Leader Achieves 70% Campaign Lift and 20% Churn Reduction with Test Transformation

Industry: Communications, Media, and Entertainment | Services: Digital Engineering Services

Client Overview

Our client is one of the largest wireless carriers in the U.S., offering mobile, broadband, and digital entertainment services. With a large customer base and frequent product updates, ensuring quality and speed in software delivery is essential to competitiveness.

The Challenge

Legacy, Manual Test Cycles Were Slow, Fragmented, and Error-prone

The client’s QA maturity was low: testing lacked automation, coverage was fragmented across UI, API, and mobile, and tests typically took 4-6 days for regressions. There was no continuous integration / continuous deployment (CI/CD) pipeline, and security testing was disconnected. The lack of test data management and automation caused long wait times, inconsistent quality, and delayed releases.

Sutherland Solution

Comprehensive test transformation using CloudTestr + test engineering excellence
To address our client’s challenges, Sutherland introduced CloudTestr, an end-to-end test automation platform that eliminates manual coding, boosting efficiency and reducing errors. CloudTestr, available both as cloud and on-prem deployments, streamlines test management, enables parallel execution, and automates documentation, improving audit and compliance. Leveraging CloudTestr, we transformed the client’s testing landscape by strategically enhancing four critical areas.

• UI Test Automation. We implemented a comprehensive automation framework to streamline the client’s regression testing, reducing the time required from 4-6 days to just six hours. This accelerated the release process, enabling quicker, more reliable updates and improving overall product quality.
• Quality Engineering CoE. We established a fully operational offshore testing lab for functional, security, integration, and performance testing. This ensured zero critical defects and enabled a seamless cloud migration, significantly enhancing the client’s operational efficiency.
• API Test Automation. Automating the migration of SOA services to RESTful microservices, we improved back-end stability and reduced testing time. This allowed for faster deployment of new features while ensuring a stable and reliable application environment.
• Mobile Testing. We set up on-premises and cloud-based testing labs for iOS and Android, eliminating manual testing and improving regression efficiency. This automation ensured consistent, high-quality performance across all mobile devices.

Sutherland also implemented a tailored solution to ensure accurate test data provisioning while maintaining environmental consistency. This approach makes testing highly repeatable, eliminating concerns about environmental factors and dependencies.

• Test Data Management. We implemented CloudTestr to streamline test data access, enabling the generation and persistence of synthetic data tailored to specific test cases. This approach optimized performance, reduced dependency on live databases, and minimized the need for in-depth database knowledge, ensuring consistent and accurate test data availability.

Containerization. We introduced containerization to enable parallel execution of regression tests, reducing testing time from several days to just one. This approach enhanced flexibility and scalability, allowing for rapid adjustments to testing resources and ensuring a consistent, efficient testing environment..

The Outcome

From days to hours—faster releases, better quality, and stronger retention

By implementing the transformation, the client experienced a 70% increase in campaign effectiveness, a 45% uplift in personalized offers, and a 20% reduction in customer churn. Test cycles shrank dramatically, enabling faster time-to-market and better alignment with digital product demands. The solution enhanced software quality, reduced defect risk, and supported the client in realizing measurable gains in customer engagement and retention.
