Together with ThoughtWorks, TietoEVRY established a delivery approach for a legacy-replacement core banking solution for 40 banks across the Nordic region, as part of the Core Renewal Programme, adopting a mix of Agile and DevOps practices. We transformed an in-flight project of over 200 people across 3 countries and 4 time zones, organising both team structures and management practices to align with agile principles. On the technical front, we also supported the re-factoring of the solution architecture, whilst implementing continuous delivery with automated testing. 

One important factor in the transformation was the use of four industry-defined key metrics that differentiate between low, medium and high performers: lead time, deployment frequency, mean time to restore (MTTR) and change fail percentage. These metrics helped the project identify and remain focussed on the most critical performance improvements, significantly reducing lead time by 75%, and increasing deployment frequency ten-fold.  

These changes took the project a significant way toward becoming a high-performer, as defined by the four key metrics, regularly delivering high-quality solutions for client testing and feedback, and cultivating the ability to adapt to change quickly. With these achievements, TietoEVRY is now using the project as an exemplar both for their own organisation and for their clients.
