Whether it’s a Model A or Model B outsource arrangement, delivery changes how test cycles need to progress, whether client teams are ready for it or not.
If you’re not familiar with the concept, in the Platform domain, outsource arrangements usually fall into one of two types (A or B). Both models see an increasing amount of activity shift to the technology vendors, including ITO, BPO, and depending on model, Custody, as well as direct regulatory and client relationships. As a result, the vendor is likely to undertake a larger portion of the testing. This requires the client to adopt different testing frameworks to ensure appropriate oversight of the supplier.
In many cases, the supplier owns both the operating platform and a large part of the operational service. The client still carries all the regulatory responsibility and accountability for quality (as it’s their legal obligation, brand, and reputation), but with far less direct involvement in how it’s delivered.
This inevitably presents a challenge.
The instinct for clients is often to step back in, to re-test, re-check, and rebuild confidence through more direct client-side activity. But that quickly leads to duplication, slower delivery, and unnecessary friction.
The real challenge lies in understanding how quality is being proven and having a framework which provides the right checks and balances without getting in the way of progress.
The limits of traditional testing in an Outsourced Platform Model
In a traditional delivery model, the client is closely involved in testing. Teams design a comprehensive Quality Assurance (QA) approach, with multiple testing phases which collectively seek to directly validate outcomes.
An outsourced model changes that.
The supplier takes on the majority of the test coverage, execution, and reporting. The client is still responsible for the quality of outcomes, but with far less involvement in how it’s delivered.
This is where tension tends to appear. When visibility feels limited, the instinct is to step back in, to re-test, re-check, and rebuild confidence independently.
It’s an understandable reaction, but it can lead to duplication, slower delivery, and may easily strain the relationship between client and supplier. More activity doesn’t necessarily lead to better assurance.
What’s needed is a shift in approach. Rather than doing more, it’s about developing further understanding of what’s happening, and what aspects need validation versus what’s already been validated.
How assurance works in an outsourced model
In outsourced environments, assurance comes from understanding how the supplier operates, and how to build confidence within that model, rather than adopting legacy processes.
It starts with visibility. Reviewing supplier test cases and evidence gives a view of how coverage is being approached. Looking at how defects are defined, prioritised, and resolved helps identify underlying quality. Tracking progress made over time highlights where risk is building.
What matters is how that information is brought together. Independent, aggregated management information (MI) provides a clearer view of progress, risk, and readiness, something stakeholders can use to make decisions.
For that to work, the MI needs to reflect how the supplier delivers. The focus should be on translating supplier outputs into something consistent, measurable and usable.
This is where a more structured approach helps. At AheadMG, we use tools such as our proprietary software tool AheadLens, to bring together test strategy, plans, defect trends, and delivery progress into a single, objective view. Developed over 15 years, it’s designed to provide clients with a clear, bespoke roadmap of changes to increase test & efficiency and effectiveness.
Where client teams should focus their efforts
With that in place, the question becomes one of where client teams add the most value.
A single, clearly defined test strategy is the starting point. It needs to be agreed and understood by both client and supplier, setting expectations on scope, boundaries, responsibilities, and how quality will be measured.
From there, the focus shifts to how well the supplier’s testing stands up. That means looking closely at coverage, particularly across outward-facing functionality and end-to-end business processes where responsibilities sit jointly across organisations.
Critical processes still need attention, even when they sit within supplier-controlled areas. Capabilities such as CASS controls and reporting may be delivered as a ‘black box’, but they still require appropriate levels of assurance from a client perspective.
None of this works without strict delivery discipline. Keeping track of actions, following things through, and holding suppliers to what’s been agreed is what keeps everything moving.
The skillset shift in an Outsourced Model
This change in focus brings a different set of expectations. Testers who are used to hands-on execution can find outsourced environments frustrating. The instinct is often to step in and do the work directly. But the value here comes from a broader skillset.
Vendor management, the ability to interpret and challenge data, domain knowledge, and an understanding of how programmes operate all become more important. The role shifts away from finding defects personally, towards making sure the right conditions exist for defects to be identified and resolved effectively.
That shift also changes how testing shows up within the programme. In outsourced delivery, testing sits closer to governance than execution. The “voice of test” needs to be clear, early, and consistent, providing a view of quality that stakeholders trust, not just data they need to interpret.
That requires confidence to challenge, but also the ability to work collaboratively with the supplier. Strong outcomes come from engagement at all levels, from detailed defect discussions through to senior stakeholder reporting.
The strongest teams reflect this. Bringing together testers with SMEs, programme leads, and vendor specialists creates a more balanced function; one that can challenge, interpret, and guide, not simply execute. For over 15 years, AheadMG has supported testing in complex delivery environments. That experience underpins how we approach outsourced models, helping firms build the right level of assurance without adding unnecessary friction.
If your organisation is operating in an outsourced environment, or moving towards one, we support firms in shaping the right testing approach and providing the oversight needed to deliver with confidence.
