DPD, one of Europe’s largest courier and logistics companies, partnered with QualityArk to validate the performance of their new package and delivery management platform. The project aimed to ensure platform reliability under heavy load, identify bottlenecks, and prevent service interruptions that could impact millions of deliveries. Our team delivered tailored testing scenarios, ran multi-month performance cycles, and helped prepare the platform for a high-stakes launch.
DPD operates across more than 50 countries, delivering 4 million+ parcels daily with a team of over 60,000 logistics professionals. Their new digital platform was designed to support real-time delivery tracking, optimize courier routes, and process transactions at scale - mission-critical for operations in both domestic and international markets.
- The platform needed to support millions of daily transactions
- High concurrency risked server overload and latency
- Created 55 real-world performance scenarios simulating courier activity, parcel tracking, and delivery events
- Some key services failed up to 8× under stress
- No clear visibility into weak points
- Detected 18 critical bottlenecks (e.g. memory leaks, DB load spikes)
- Partnered with devs to address root causes
- Agile changes introduced performance drift
- Need for performance assurance over time
- Regular load cycles ensured stability across updates
- Re-tested to catch regressions before go-live
bottlenecks resolved before public rollout
Previously unstable components became fully production-ready
during pilot or full deployment phases
System successfully handled millions of daily transactions
performance scenarios created to reflect real-time logistics and courier behaviors
Avoided downtime-related losses, potentially amounting to millions in damages
Reinforced platform reliability and operational trust
9 months of cyclic testing ensured quality across iterative updates
