Both sites had been built in Drupal 7, a version that was about to go End-of-life. So from a security perspective, it was important to get the sites running on a higher Drupal version in a timely manner. Drupal 9 was chosen, at that time the most recent (and stable) Drupal version. Since there is no easy update from Drupal 7 to Drupal 9, this meant rebuilding the sites.
We analyzed the existing websites. RSVZ wished to keep all the functionalities of the websites. This presented a challenge since Drupal 9 works fundamentally differently from Drupal 7 in some areas. Web forms are a good example.
RSVZ is consciously working to improve the user experience of the website. Building a new website was a great opportunity for them to implement additional optimizations in terms of user experience, in addition to refreshing the design. They had a UX audit performed and this resulted in a proposal for the new site in the form of wireframes.
Furthermore, web accessibility was an important pillar. The website had to be easily usable by everyone. Think of the visually impaired or blind, but also, for example, people with limited hand function or limited reading skills.
