Telefónica Deutschland is one of the leading integrated telecommunications providers in Germany, serving more than 45 million mobile accesses and 2.4 million broadband accesses. It is one of the largest telephone operators and mobile network providers in the world. It provides fixed and mobile telephony, broadband, and subscription television, operating in Europe & USA.
Over the past two decades, Telefonica has managed over 12 brands across six IT stacks, with a portfolio spanning more than 600 applications, resulting in a historically grown complexity. This complexity has led to challenges such as a lack of customer centricity and personalisation, brand-specific processes, and longer time-to-market for products and services. Additionally, sluggish alignment to regulatory changes, coupled with the anticipation of voluminous growth with the advent of 5G technology, further exacerbates the need for streamlined processes and enhanced agility.

The Telefónica Radical Architecture and IT Transformation program aims to simplify the architecture, speed up and transform the IT, reduce the number of partners for application development and give them also the responsibility for the operations of the application.
With white-labelling, the goal is to create the most value and impact for every development hour. The goal is to standardise and optimise as many steps/ capabilities as possible while maintaining unique layout capabilities for each brand.












Embarking on the journey for DEI , I delve into the depths of my experience working as a UX designer, exploring the intricacies of the process, the insights gained, and the lessons learned along the way. My role extended beyond crafting interfaces; it encompassed understanding user behaviours, empathising with their needs, and orchestrating design solutions that resonate deeply. DEI also helped me acknowledge the collaborative nature of the project, involving stakeholders, designers, developers, and now the users. I understood how effective communication and collaboration fostered a shared vision and facilitated the alignment of design goals with business objectives.
