A Mexican financial institution with operations in banking, investment funds, insurance, and trading achieved over 50,000 new client acquisitions after launching its new digital channel, supported by a dedicated Quality Engineering team from MTP. The key was replacing a shared and rotating testing model—which led to knowledge loss and recurring errors in onboarding and contracting processes—with a specialized team providing exclusive technical leadership for the product. Operational stabilization occurred in approximately three months.
Over 50,000 New Clients: How a Dedicated QA Team Unlocked the Potential of a Strategic Financial Product
The Context: A Key Product Without the QA It Deserved
A Mexican financial institution with operations in banking, investment funds, insurance, and trading faced the challenge of launching a new digital channel, highly relevant to its growth strategy. The product was a priority for the organization. The validation process was not.
Testing for the new channel was carried out by a shared and rotating team that simultaneously handled multiple projects. The result was predictable: knowledge loss between sprints, low coverage in critical flows, recurring functional errors in onboarding, contracting, and transaction processes, and misconfigured environments that created confusion about what constituted a real defect versus an environment error.
Additionally, the project lacked physical mobile devices—Android and iOS—to validate real user scenarios. Supposed “stoppers” blocked entire sprints due to issues unrelated to the product. The backlog grew. Deadlines were compromised. And trust between the QA team and the development and business teams deteriorated.
The cost was twofold: operational and strategic. Operational, because each unstable sprint accumulated quality debt. Strategic, because the product could not fulfill its promise of attracting new clients if the account opening experience failed. In a digital financial product, the first transaction—account opening—is the ultimate test of user trust.
The Solution: A Dedicated Team with Exclusive Technical Leadership for the Product
The Digital Channels Directorate decided to scale QA capacity with a different approach: no more generic shared resources, but a specialized team led by a technical profile with business knowledge and a strategic vision for the product. MTP was designated to form and operate this team.
The transition was built on four pillars:
- Team dedicated exclusively to the channel. A group of specialists in functional testing, integration validations, and mobile QA was formed, available full-time for the product—without the fragmented attention of the previous model.
- Structured knowledge transfer. Instead of starting from scratch, MTP leveraged the existing foundation and extended it with formal documentation and transfer processes. Each sprint began with complete context, not assumptions.
- Analysis and monitoring tools. Burp Proxy was incorporated for visibility into application traffic, along with standardized deliverables aligned with agile methodologies.
- Trust as an operational indicator. During the first three stabilization sprints, MTP not only executed tests: it earned the trust of the development team and internal and external business stakeholders, under real pressure to meet already committed deadlines.
The model worked. Stabilization took approximately three months. From then on, the product operated with monthly releases focused on quality and continuous improvement, with a solid testing foundation that enabled frequent updates without compromising channel stability.
Key Metrics
| Indicator | Result |
| New client acquisitions after launch | +50,000 |
| QA team stabilization time | ~3 months (3 sprints) |
| Post-stabilization release cadence | Monthly, with continuous improvement |
| Production incidents post-stabilization | Sustained reduction (quantification recommended before publishing) |
Editorial Note: The result of +50,000 client acquisitions is a business outcome enabled by product quality. To strengthen the case’s credibility with a technical decision-maker or CFO, it is recommended to supplement with direct QA metrics: defect rate before/after, resolution speed, or coverage percentage achieved.
Measurement Methodology
The +50,000 client acquisitions figure was reported by the organization as a result of the product launch post-stabilization. The three-month stabilization period corresponds to the time between the formation of the dedicated MTP team and the first release with consistent quality, measured by sprint cadence and backlog status. Production incidents were monitored through the development team’s internal tracking system, with greater visibility once MTP standardized QA deliverables.
