DNB Lithuania

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 Miles 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 applications 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 banking hours.

Solution

Miles 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 of December 2016 to Euros. A dedicated five-member team from Miles worked closely with 150 DNB system experts to plan and execute the conversion event. Miles played an important role in formulating a 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. Miles also closely worked with the planning and risk mitigation team to ensure data integrity.

Results

After one year of 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 Internet banking and mobile banking resumed operations. All the bank branches, ATMs, and payment cards operate as usual.
