Challenge
The wind of change was blowing strong in Lithuania's financial sector and on 1st January 2015 the Republic of Lithuania
became the 19th member country of the Eurozone. The country's third largest bank Lithuania partnered with Tardis to
aid its customers through challenging times and convert all their information from Litas to Euros.
Banking applications are considered to be one of the most complex applications in today's software development and testing industry.
What makes Banking application so complex? Banking has a massive storage system with a lot of multi-tier functionality to support
thousands of concurrent user sessions and the application integrates with numerous other applications that link with consumer loans, pay utility and trade accounts. There are complex business workflows with real time and batch processing. Also, any changes to the systems could be made only after the banking hours.
Solution
Tardis spent a full year preparing at the backend for a 32 hour transition window which would move all information and accounts of the bank on the 31st December 2016 to Euros. A dedicated five-member team from Tardis India worked closely with 150 DNB system experts to plan and execute the conversion event. Tardis played an important role in formulating high-level conversion strategy to link 30 IT systems to the new currency with the primary objective of reducing the impact on the overall integration architecture at the bank. We defined a delivery model with smaller measurable and independent work items. We assisted DNB in the execution and reconciliation of the system conversion. Tardis also closely worked in planning and risk mitigation team to ensure data integrity.
Result
After one-year preparations DNB bank's information systems from 31 December 2014 to 1 January 2015 were successfully revised to the Euro- the new currency of the Republic of Lithuania. On 2nd January the Internet banking and mobile banking has resumed operations. All the bank branches, ATMs and payment cards operate as usual.
