OWNING CHANGE IN FINANCIAL SERVICES
Our customer is among the largest banking and financial services institutions in the world, serving millions of clients.
THE CHALLENGE:
Embedding Compliance at the Core
Our customer needed to urgently rebuild their core banking systems to comply with new mandates imposed by the national financial regulatory institution, which necessitated recovery times of under 30 minutes across all core banking systems. This was a business-critical mandate with no room for delay, and our customer moved decisively to protect their standing as one of the world's largest banking and financial services institutions.
Delivering on this mandate meant testing and upgrading over 19 interconnected banking systems, with each phase spanning six to nine months and several running concurrently under a single, tightly governed programme. This required a technical partner with genuine depth in financial services testing disciplines, capable of validating failover, disaster recovery, and transaction integrity across a highly complex, regulation-bound landscape, without introducing risk to live banking operations.
OUR PROPOSAL:
Comprehensive Testing and Quality Assurance Uplift
TEKsystems translated our customer's regulatory roadmap into an executable, milestone-driven test strategy spanning all 19 in-scope systems, grounded in deep domain expertise across financial services testing and regulatory compliance. We then stood up a structured testing operating model to ensure compliance at every phase of the programme, from initial scoping through to final sign-off.
- Test Strategy: Sequenced 19 interconnected banking systems into structured six-to-nine-month upgrade cycles, engineering each milestone to align precisely with the regulatory deadline while protecting live production stability and minimising cross-system dependency risk.
- Comprehensive Execution: Designed and executed comprehensive functional and non-functional test suites covering transaction processing, failover behaviour, and disaster recovery scenarios across all 19 systems simultaneously, validating performance under both standard and peak-load conditions.
- Defect Triage: Implemented a structured, root-cause-led defect management lifecycle that isolated systemic issues surfaced during execution early, protecting release timelines, minimising rework, and preventing recurrence across subsequent upgrade phases.
- Regression Governance: Built and maintained repeatable, version-controlled regression suites to safeguard platform stability as multiple upgrade phases progressed in parallel, ensuring no previously validated functionality regressed during later releases.
- Stakeholder Reporting: Ran weekly governance forums delivering KPI dashboards, risk registers, and clear escalation pathways throughout, giving our customer's leadership continuous, real-time visibility into programme health and emerging risk.
REAL–WORLD RESULTS:
TEKsystems' engagement enabled our customer to eliminate their regulatory exposure well ahead of the deadline, protecting the business from potential breaches and financial penalties at a critical juncture. Our impact has scaled into a multi-year strategic partnership underpinning our customer's ongoing core banking modernisation across multiple geographies.
- Full Compliance: Achieved full regulatory compliance across all 19 systems, removing our customer's exposure to hefty penalties and reputational risk well in advance of the enforcement window.
- Risk Mitigation: Closed out the programme's highest-priority regulatory risk well ahead of the compliance cut-off, giving leadership early assurance and freeing capacity to focus on other strategic priorities.
- Seamless Operational Continuity: Sustained live banking operations throughout the entire multi-phase programme with zero disruption to customer-facing services, even during the most technically demanding upgrade windows.
- Enhanced Testing Standards: Set a new internal benchmark for testing rigour and governance, since applied to our customer's subsequent system modernisation programmes across other business units.
- Expanded Strategic Partnership: Established TEKsystems as one of our customer's most trusted technical partners for regulatory-critical banking initiatives, opening the door to further strategic engagements.
