"Digital Transformation thru EU IT Reference Architecture" by Deutsche Telekom wins 4 Awards in 2021

Updated: Aug 26, 2022

Prior to 2017, Deutsche Telekom’s approach to IT and digital capabilities in the European segment was de-centralized and fragmented. Penetration of digital transactions was low, and there was insufficient investment in the platforms and technologies required to address this. It quickly became apparent that to efficiently drive the needed step change, a more unified approach was required- one that leveraged the scale of the group, addressed the shortage of the necessary skills required for this transformation, and most critically, built upon the insight that, for digital platforms at least, it can often be simpler to harmonise requirements, and then solve something once and then deploy it to many.

Hence, “EIRA” was born, Europe-wide framework that articulates how to transform our legacy IT architecture into the digital world and what capabilities we need to make that transition​. The objective of EU IT Reference Architecture (EIRA) is to provide a detailed view on transformation to digital enterprise, including business capabilities, enabling digital platform services, transforming legacy applications, delivering new operating model and transition architecture approach​.
