Investec faces major global testing challenge

London-based Investec is preparing for a major software testing and quality assurance programme after hiring Infosys to deploy its cloud-native Finacle banking platform across the wealth manager’s operations in South Africa, the UK, Mauritius and the Channel Islands.

The international financial firm plans to migrate from its legacy platforms to the Finacle Digital Banking Solution Suite running on Microsoft Azure.

The multi-country transformation will require Investec to move several critical banking operations onto a multi-region SaaS platform without disrupting customers, compromising data integrity or falling short of regulatory requirements, requiring extensive trialling, testing and monitoring throughout the process.

In a statement, Investec said the programme covers deposits, lending, virtual accounts and liquidity management, creating a substantial testing challenge across inter-connected software systems, data flows and jurisdictions.

For Investec’s QA and engineering teams, the work will go well beyond validating whether the new platform functions as expected.

The bank will need to test legacy data migration, reconciliation, customer journeys, APIs, regional configurations, platform performance, cyber controls and operational resilience.

It will also need to demonstrate that critical services remain available during the transition and that calculations, balances and customer records remain accurate as operations move between old and new systems.

Lyndon Subroyen, global head of digital and technology for Investec Group, described the agreement with Infosys Finacle and Microsoft Azure as a significant step in the bank’s modernisation.

“Our partnership with Infosys Finacle and Microsoft Azure marks a step change in our digital transformation journey,” Subroyen eplained.

“We are building a stronger digital foundation that allows us to scale with our clients, deliver a more seamless and personalized experience, and operate with greater precision.”

He added: “Digital is no longer a layer that supports the business, it is integral to how we grow, deepen client relationships, and improve our efficiency.”

Multi-country testing challenge

Subroyen said Investec will adopt the Finacle Deposits Suite, Finacle Lending Suite, Finacle Virtual Accounts Management and Finacle Liquidity Management Solution through a multi-region SaaS deployment.

Bringing these capabilities together creates complicated testing dependencies. A change to account data, for example, could affect lending, liquidity calculations, corporate cash management, reconciliation and customer-facing channels.

Testing teams will therefore need to validate complete banking journeys across the platform rather than assessing each component in isolation.

The geographical reach of the programme adds another layer of complexity. Investec will need to accommodate different products, customer expectations and regulatory obligations across four jurisdictions while maintaining a consistent underlying technology platform.

Regional configurations will require their own testing, but Investec must also ensure that localisation does not undermine shared controls, performance or interoperability.

Sajit Vijayakumar, chief executive officer of Infosys Finacle, said the platform is intended to support faster innovation and more intelligent customer experiences.

“We are committed to helping banks accelerate growth by inspiring better banking,” he said.

“Our cloud-native banking solutions are designed to help institutions like Investec accelerate innovation, strengthen operational agility, and deliver more intelligent and personalized experiences at scale.”

Vijayakumar added: “By combining open APIs and events-driven architecture, with strong data and AI foundations, Finacle will empower Investec to stay ahead of evolving client expectations and unlock new avenues for value creation and delivery.”

Those open APIs and event-driven services will be central to the transformation, but they will also expand its testing surface. Investec must validate how the Finacle environment exchanges information with existing applications, third-party platforms and the wider fintech ecosystem.

That means testing API contracts, authentication, data formats, transaction sequencing and failure handling, alongside the functionality visible to customers and employees.

Migration assurance

Data migration will be one of the most sensitive elements of the programme. Moving deposits, lending records, virtual account structures and liquidity information away from legacy platforms will require extensive validation and reconciliation.

QA teams will need to prove that records remain complete and accurate, balances are preserved and transactions are not lost or duplicated during the transition.

The complexity increases if Investec introduces the platform through phased regional or product rollouts. Legacy and Finacle environments may need to operate alongside each other for a period, making interoperability, synchronisation and regression testing essential.

The bank will also need to test how the platform performs during periods of high transaction activity, infrastructure degradation and regional disruption.

Running Finacle across multiple Azure regions can support resilience, but geographic distribution does not itself prove that services will fail over cleanly or continue operating within acceptable limits.

Failover, recovery and continuity therefore need to be tested under realistic operating conditions.

Similar issues have emerged in Infosys’ work with Norway’s DNB Bank, which is consolidating financial-crime controls onto NICE Actimize’s X-Sight Enterprise SaaS platform.

That programme involves enterprise architecture, platform integration and data migration, with QA positioned as a control over operational stability, regulatory compliance and customer outcomes.

Elin Sandnes, COO and group executive vice president technology and services at DNB, said: “Protecting customers and the integrity of the financial system requires us to continuously raise the bar.”

“By working closely with Infosys and leveraging NICE Actimize’s X–Sight Enterprise platform, we are enhancing our ability to support our long–term digital transformation and regulatory compliance objectives.”

Sandnes previously stressed the importance of assurance during DNB’s wider technology modernisation.

“Robust testing and quality assurance processes will play a critical role in ensuring operational stability and customer satisfaction,” she said.

Dennis Gada, executive vice president and global head of banking and financial services at Infosys, also linked testing directly to the resilience of major banking transformations.

“Large-scale IT transformations enables DNB to remain resilient while embracing rapid change,” he said. “Testing every phase of the transformation ensures that systems are robust, secure, and capable of meeting evolving customer expectations.”

The same principle applies to Investec. Testing cannot be deferred until the platform approaches production because migration design, data mapping, integration architecture and regional configuration can introduce risks much earlier in the programme.

SaaS changes the QA model

Adopting Finacle as a SaaS platform will also change how Investec approaches regression testing and release assurance.

Unlike a traditional core platform controlled entirely through internal release cycles, SaaS environments evolve through vendor-led upgrades and continuous platform changes. Investec will therefore require repeatable automated tests capable of confirming that essential banking journeys still work after each change.

The bank will also need clear controls around release approval, environment management and production monitoring. While a cloud-native platform can support faster delivery, that increased pace can place more pressure on testing, security and governance.

This issue is central to Infosys’ separate collaboration with software delivery specialist Harness, which targets the growing bottleneck between AI-accelerated development and safe production deployment.

Jyoti Bansal, co-founder and chief executive officer of Harness, described the problem as the “AI Velocity Paradox,” where “development speeds up, but downstream processes like testing, security, compliance, and deployment struggle to keep pace, introducing new risk and complexity.”

Infosys chief executive Salil Parekh made a similar argument. “As AI accelerates change, banks need delivery systems that are faster, reliable, and governed by design,” Parekh said.

He described the aim as “a more disciplined path from innovation to production, embedding security, compliance, and resilience into how software is delivered across complex environments.”

For Investec, that discipline will be particularly important because the Finacle implementation is intended to provide data and AI foundations for future services.

Before the bank can scale AI-enabled banking experiences, it will need to establish that the underlying data is accurate, sufficiently complete and consistently governed.

Any defects or inconsistencies introduced during migration could otherwise be inherited by analytics and AI systems built on top of the new platform.

Testing will consequently need to cover not only individual applications but also the quality and lineage of the information moving through the platform.

Wider Infosys banking push

The Investec agreement extends Infosys’ growing involvement in cloud transformation and quality engineering across financial services.

In addition to its DNB programme and Harness partnership, the company has worked with Metro Bank on the modernisation of finance and operational systems and expanded its European presence through a new hub in Zurich.

The Swiss operation is focused on cloud transformation, AI-led modernisation, operational resilience, security and compliance. Its launch reflects Infosys’ efforts to bring consulting, engineering and quality capabilities closer to financial institutions managing complex regulatory and technology estates.

Infosys has also been investing in AI-powered agents intended to automate elements of regression testing, defect detection and performance monitoring.

Balakrishna D. R., executive vice president and global services head for AI at Infosys, said: “Weare enhancing Human+AI collaboration and unlocking new levels of efficiency and precision across the finance space.”

“These agents not only support complex operations but also strengthen our clients’ ability to maintain software quality testing at scale.”

Automation could help Investec manage the volume of regression testing created by a multi-product SaaS platform. However, automated test execution will still depend on reliable test data, representative environments and controls governing how defects and anomalous results are assessed.

Investec scales AI adoption

The Finacle migration also forms part of a much wider AI and cloud transformation at Investec. In June, the bank rolled out Microsoft Copilot to all 8,000 employees globally, while confirming that more than 800 AI agents were already active across the group.

Investec said the agents were automating repetitive work and improving the speed, quality and consistency of internal processes, collectively releasing more than 350,000 working hours annually.

“Our AI strategy is built on a simple thesis: higher tech leads to higher touch,” Subroyen explained. “AI is an amplifier of our people and their judgement, not a substitute for either.”

Subroyen added: “The opportunity is not simply to do things faster; it is to create more capacity for the work only people can do, building trust, exercising judgement, solving complex problems and delivering exceptional client experiences. Investec will remain human-led.”

As AI becomes embedded across activities ranging from onboarding to servicing and operations, the reliability of Investec’s underlying platforms, integrations and data will become increasingly important.

The Finacle programme will therefore need to provide not only a scalable foundation for AI, but one whose quality, resilience and controls can be continuously tested.

Quality as control layer

Investec’s adoption of Finacle reflects a broader change in banking transformation. Quality assurance is moving away from final-stage software validation and becoming a continuous control across architecture, migration, deployment and production.

The benefits promoted by Infosys, including faster lending journeys, real-time reconciliation, enhanced liquidity visibility, open API connectivity and greater use of AI, depend on the reliability of the platform and the data moving through it.

Each benefit therefore creates a corresponding assurance requirement. Real-time reconciliation must be tested for accuracy and exception handling. Liquidity information must remain reliable during infrastructure or integration failures.

Lending journeys must work consistently from application through decision and servicing. APIs must remain secure and dependable as new partners and services connect to the platform.

The central challenge for Investec will be to achieve this while replacing legacy technology across several markets without weakening day-to-day operational control.

The Finacle programme may give the bank a more scalable and adaptable technology foundation. Whether it delivers that outcome safely will depend heavily on Investec’s ability to test every stage of the migration, continuously validate the resulting SaaS environment and produce evidence that the new platform remains resilient across all four jurisdictions.
