Delivering Next Generation Banking Architecture Program for a Major Private Bank in Turkey

Automation brought about 18M € reduction in costs and saved 780 person-day.

Business Challenge

Creating a next generation banking architecture program solved serious bottlenecks that the legacy mainframe was causing and unlocked substantial value.

Our client was the second largest private bank in Turkey with subsidiaries in pension and life insurance, leasing, factoring, brokerage and asset management, besides international subsidiaries in Europe. They were highly dependent on their legacy mainframe. This was causing serious bottlenecks. Challenges and business objectives required the creation of a next generation banking architecture program. These objectives were:
- Deliver new business products faster
- Attract and retain talent in the organization
- Enable new talent to become productive in shorter amount of time
- Improve talent productivity (architects, developers, SREs)
- Accelerate innovation in the organization
- Modernize the core and manage obsolete technologies on legacy systems
- Reduce legacy systems complexity
- Reduce cost using distributed open environment
- Improve business operations through modern technology
How we helped?

DefineX partnered with the bank to analyze and create the next-gen architecture roadmap.

Partnering with them in the Next-Gen Architecture Program since the beginning of their transformation journey, we provided guidance for the initial roadmap development and actively participated in development throughout this roadmap.

We involved various project teams which included a wide range of roles (PM, Architect, Developer, and Change Enablers):
- Assistance to Business Enablement Projects with our Program Management Expertise.
- Delivery of planned/ additional architecture features and components with the bank
- Applying next-gen architecture know-how, emerging technologies and abilities.
- Defining KPIs to track Development Issues and implementing improvements in the program, evolving Developer Experience to increase attrition
- Creating and developing an Open-Source Framework for the Platform
