Client Overview

Large private bank embarked on a major digital transformation to modernize its mobile banking platform following a merger with a leading finance company. With over 80 million users relying on the digital retail banking channel, the bank aimed to modernize its digital platforms, deliver high‑quality, defect‑free experiences across web and mobile, and ensure resilient performance across diverse devices and environments.

To support this ambitious vision, QualityKiosk Technologies was entrusted with spearheading customer experience (CX) and device performance engineering across critical touchpoints.

Business Challenges

Massive user risk

Supporting over 80 million active users introduced significant risks to service continuity, data integrity, and customer trust in the event of performance issues.

High-stakes digital experience

With millions relying on mobile and web platforms daily, even minor glitches could lead to customer dissatisfaction and reputational damage.

Device & environment fragmentation

Delivering a consistent user experience across a fragmented device landscape posed a significant testing and validation challenge.

Limited visibility into live issues

The bank required real-time insights to catch experience-breaking issues before customers encountered them.

Need for round-the-clock reliability

Maintaining uninterrupted banking services across time zones demanded constant vigilance and instant response mechanisms.

Complex infrastructure landscape

Operating across a hybrid infrastructure of multi-cloud and on-premises systems added layers of coordination and complexity, heightening the risk of journey failures.

QualityKiosk’s Approach and Solution

QualityKiosk adopted a CX‑first, NFR‑led engineering approach to help the bank deliver reliable, high‑quality digital experiences at scale, even in the complexity of a post‑merger environment.

  • CX‑first engineering strategy: We began by mapping critical mobile and web banking journeys and identifying high‑risk, high‑impact touchpoints. This ensured testing and monitoring efforts were aligned directly with customer experience and business outcomes.

 

  • Embedded validation across agile delivery: CX, performance, and device validation were embedded into agile sprints, enabling early detection of experience‑breaking issues and continuous feedback throughout the development lifecycle.

 

  • Proactive observability & monitoring: QualityKiosk implemented journey‑level synthetic monitoring, real‑time alerts, and business‑aligned dashboards to proactively detect issues before they reached customers, ensuring uninterrupted banking services.

 

  • Device & environment coverage at scale: Digital journeys were validated across 50+ device and network combinations using a hybrid cloud and physical device lab, ensuring consistent experiences across fragmented environments.

 

  • Resilient, scalable execution: The approach combined continuous monitoring, automated validation, and iterative optimization, allowing the bank to scale new digital offerings rapidly without compromising stability or performance.
