Sample of the UI pattern library
Overview
We were a team of 9 developers and 7 designers working to build and maintain the online presence of six brands – each of them having a separate site – which offer telephone service products in Germany and eight other European countries.

Background and strategic fit
From the design perspective, we wanted to create a seamless user experience across different brands and platforms. Additionally, we intended to cut down drastically the time spent on prototyping, so that we could get buy-in for testing small and often in all projects.
From the design perspective, we wanted to create a seamless user experience across different brands and platforms. Additionally, we intended to cut down drastically the time spent on prototyping, so that we could get buy-in for testing small and often in all projects.
Since we had no dedicated team for this project, we took the so-called slow drip approach, that accounts for lower effort at initial stages. Taking advantage of the relaunch of Secretaría.es happening in parallel, elements were added to the styleguide as new UI components were created and the library is planned to grow organically as needs arise.

Outcome & results
This project is still ongoing, although some observations can already be made:
This project is still ongoing, although some observations can already be made:
- After introducing a shared component library, up to 3 team members could be contributing to a website redesign. This is a big improvement compared to previous projects, on which only one designer was appointed and the occasional collaboration was cumbersome.
- The time spent on prototyping all page templates for Secretaría.es was 16 hours (reduction of approximately one-third compared to previous projects).
