The Obstacle

Caja Popular Mexicana (CPM) plays a critical role in Mexico’s financial ecosystem. As a cooperative collectively owned by more than 3.9 million members, it exists not to maximize short-term profit, but rather to expand access to fair, responsible financial services—particularly for individuals and families historically underserved by traditional banking institutions. Through affordable savings and credit products, CPM helps members strengthen financial stability, invest in education and entrepreneurship, and build long-term economic resilience.

This mission is especially important in a market in which many low-income consumers had previously faced limited access to formal financial services and often only had access to high-cost lending alternatives—even as the financial services landscape evolved, CPM’s legacy operating model had begun to constrain its ability to scale impact.

The organization had been highly branch centric, with limited digital capabilities and processes that could take hours for members to complete, such as applying for credit. At the same time, its technology environment had grown increasingly complex, with more than 400 system integrations supporting core services—limiting agility, slowing innovation, and making it difficult to introduce new products quickly.

Limited automation, a lack of architectural governance, and dependence on external vendors only compounded these challenges. As new competitors entered the market with faster, more flexible digital offerings, CPM faced a growing gap between its mission and its ability to deliver services at the necessary speed and scale.

For CPM, the challenge was clear: how to modernize its technology and operating model in a way that would not only improve efficiency but also expand access to affordable financial services and strengthen its longstanding social mission.

Our current system has been with us for many years, and we wanted to upgrade it. But the system alone won’t change everything. We also needed a much better operating model. — Ricardo Lopez Enriquez, Director General, Caja Popular Mexicana

Our Approach

To address these challenges, CPM partnered with BCG to design and implement a comprehensive transformation—one that would modernize its technology foundation while enabling the organization to scale its mission.

The starting point was to define a clear target operating model and technology architecture that could support faster, more flexible financial services. Rather than focusing on incremental improvements, the transformation aimed to fundamentally reshape how CPM delivers value to its members.

At the core of this effort was the transition from a legacy, tightly coupled system to a modern, decoupled architecture. This included adopting microservices, DevSecOps practices, and industry standards such as BIAN and OpenAPI—enabling CPM to reduce time to market for new products and respond more quickly to member needs.

In parallel, the joint team developed a capability roadmap to guide the transformation over time. This roadmap defined the technical and organizational capabilities required to progressively build and scale the new operating model, ensuring that change could be implemented in stages without disrupting day-to-day operations.

A strong emphasis was placed on governance and internal capability building. New structures, including a Design Authority and enhanced technology governance processes, were introduced to ensure consistency in architectural decisions and reduce long-term dependency on external vendors.

At the same time, CPM strengthened its internal teams and ways of working, introducing more agile, DevSecOps-based approaches and improving coordination across technology, architecture, and operations.

Together, these elements created a scalable foundation—one that allows CPM to deliver faster, more accessible financial services while maintaining the flexibility to evolve over time.

The Result

Although the transformation is ongoing, CPM is already seeing meaningful progress across both its operations and its ability to deliver on its mission.

One of the most immediate impacts has been the strengthening of internal technology capabilities. Teams are now better coordinated, with clearer visibility into workloads, roles, and responsibilities. What was once perceived as a “black box” has evolved into a more transparent, structured, and manageable system.

The introduction of agile methodologies and improved governance has enabled faster decision-making and more efficient execution. A defined roadmap and transition model now guide the transformation, allowing CPM to modernize its systems while continuing to serve members without disruption.

These operational improvements are already laying the groundwork for broader impact.

By modernizing its technology and operating model, CPM is positioning itself to reach a significantly larger portion of the Mexican population—particularly individuals who currently lack access to affordable financial services.

The transformation is expected to extend access to credit and financial services to more than a million additional Mexicans over the next five years. At the same time, improved speed, segmentation, and multichannel delivery will enable CPM to offer more tailored and accessible financial solutions.

Crucially, the transformation reinforces CPM’s core mission: providing affordable technology and products for its members.

Beyond operational and technological improvements, the transformation also carries broader societal implications. By expanding access to fair, responsible financial services, CPM is helping to support entrepreneurship, improve financial resilience, and create new economic opportunities in underserved communities.

For CPM, the transformation is not simply about modernization—it is about scaling impact.

For other organizations, the case highlights several key lessons:

  • Technology transformation must be paired with a clear operating model and governance framework.
  • Building internal capabilities is essential for long-term sustainability.
  • Architectural discipline can reduce complexity while accelerating innovation.
  • Aligning transformation with a strong social mission can amplify both business and societal outcomes.
