The Story
Deutsche Telekom (DT) is one of the largest telecommunications providers in Europe, offering a wide range of services, including mobile communications, broadband, and fixed-line internet. With a reputation for innovation and reliability, DT is a key player in connecting millions of people and businesses across Germany and beyond.
At the heart of DT’s operations lies DTAG SEAL, an architectural solution that serves as the backbone of their provisioning, maintenance, and inventory systems. SEAL handles all business-critical requests, ensuring that customer demands are met efficiently and accurately. As DT expands its reach, leveraging copper and fiber internet technologies, SEAL plays a crucial role in maintaining seamless operations.
The Challenges
Operating at the scale of Deutsche Telekom presents unique challenges:
Production issues can result in substantial financial losses and disrupt services for millions of customers. Minimizing errors and downtime was a top priority.
DT values a multi-vendor approach to avoid dependency on a single provider. This results in a complex network of varying elements, each requiring seamless integration. All use cases and workflows needed to function uniformly across diverse vendor systems.
As one of Germany’s largest internet providers, maintaining robust security protocols was non-negotiable. The architecture needed to safeguard sensitive data and protect against potential cyber threats.
The Solution
Initially engaged for Quality Assurance (QA), our team was instrumental in identifying and addressing production issues within SEAL. By implementing systematic testing processes and proactive monitoring, we significantly reduced the occurrence of bugs and eliminated production disruptions. Key steps included:
Building on this success, our role expanded beyond QA. Recognizing our deep understanding of SEAL and DT’s business requirements, the client entrusted us with software development responsibilities. This transition included:
Through our partnership, DT has experienced:
Deutsche Telekom has expressed high satisfaction with our contributions, valuing the proactive and collaborative approach we bring to the table. Our ongoing partnership continues to drive innovation and operational excellence within DTAG SEAL and beyond.
