The Challenge
Citibanamex, a part of Citibank corporation, was facing a challenge in keeping up with the rapidly evolving Mexican consumer banking market. The bank's primary goal was to deliver a seamless, personalized user experience across both digital and traditional channels. The bank's mobile application rating was a mere 2.0 out of 5, indicating a need for innovative digital offerings to improve the user experience. The bank's core technology stack was a proprietary mainframe system, which ran core business applications such as payments and account management. Over time, modernization projects led to an increasing spiral of complexity with various tools, mainframe gateways, ESBs, middleware, dispatchers, routers, and messaging queues. Each system had a different way of handling the backend legacy platform, making it harder and more cumbersome to integrate with legacy applications. After years of unsuccessful, costly integration attempts, Citibanamex was left with the same needs and challenges, only exacerbated. The focus shifted to the Customer Digital Experience and the End-User Journey, and they needed a partner that could help them rapidly develop and deploy innovative customer offerings on top of their core systems.

Citibanamex

About The Customer
Citibanamex, founded in 1884, is a part of Citibank corporation. With 40,000 employees and tens of millions of customers, the bank processes over 40% of total transactions in Mexico. The bank was committed to a digital transformation to keep up with the dynamic, rapidly evolving Mexican consumer banking market. The bank's primary goal was to deliver a seamless, personalized user experience across both digital and traditional channels. The bank's core technology stack was a proprietary mainframe system, which ran core business applications such as payments and account management.
The Solution
Citibanamex approached OpenLegacy to expose all of their core banking applications, including Account Opening, Checking and Debit Accounts, Consumer Credit (Personal, Autos, Mortgage), Payments and Investments. OpenLegacy's connector for the mainframe environment, combined with its COBOL parser and automated API generator, resulted in a working prototype exposing six real-world mainframe business flows as APIs. The prototype only took two weeks to complete. It bypassed their Tibco middleware and messaging technologies, and instead connected directly with the mainframe environment. The new APIs generated by OpenLegacy were tested and deployed using the bank’s existing environment, to ensure that they function properly in the current infrastructure as well as follow the bank’s internal integration standards. The development was done using modern, scalable, open architecture (such as REST API) and development methodologies (Agile, Scrum) – complying with the bank’s requirements.
Operational Impact
  • Citibanamex's OpenLegacy integration enabled it to begin capturing the promise of an API Factory: the ability to automatically generate, test, and deploy standard APIs driven by business needs. The results became rapidly apparent as the Citibanamex team rolled out improvement after improvement to the mobile app, including an improved user interface and new features around digital payments. Beyond achieving its core KPI, the bank saw a number of transformational results with their OpenLegacy implementation: an acceleration in speed-to-market, improved customer experience, lower cost, and greater agility and innovation. The bank's business units can now dream up—and realize—unlimited new consumer services, offerings, and products.
Quantitative Benefit
  • Within its first quarter, Citibanamex deployed 40 APIs from its core technology.
  • To date they have deployed over 300 services as part of this modernization process.
  • The mobile app’s rating soared from 2.0 to over 4.5.
