The portal was developed to offer citizens a complete, simple, understandable and useful tool under all conditions. The first, indispensable quality of a public website is accessibility, or the ability to access the site regardless of any technical, physical or environmental limitations. Another characteristic now considered essential is responsive design, or the site’s ability to adapt automatically to the size of the user’s device (computer, tablet or smartphone) to make it easy to read and navigate.
This portal guarantees compliance with the technical requirements provided in Annex A of the Law of 4/2004 ‘Provisions to support access to information technology for the disabled’ (known as the Stanca Act), and it was developed with HTML5 mark-up language and CSS style sheets.
The development of this portal was done in numerous phases, each with different quality testing points for both usability and accessibility. Each page model underwent testing using automatic validation tools and then manual testing, following the methods indicated in Annex A to the Stanca Act.

Operating system and browser compatibility

This portal was designed and tested to ensure maximum compatibility with the main operating systems and browsers, from both a functional and visual perspective. 
This website was then tested with:

•    Safari 11 (on Mac and iPad) 
•    Internet Explorer 11 (on PC) 

Operating systems 
•    Mac Os X 10.13

Usability tests

The desktop and mobile versions of this portal were subjected to various kinds of usability tests in all design and implementation phases.

1. heuristic evaluation performed by an expert on the first graphic drafts of the portal allowed the identification of the most obvious problems. The analysis criteria used, the 12 heuristics, are the ones defined in Annex B of the Ministerial Decree of 8 July 2005 (perception, understandability, operability, consistency, protection of health, safety, transparency, ease of learning, help and documentation, error tolerance, aesthetics, flexibility);

2. summative testing performed by a variable panel of about 50 users of internal portals for the regional administration. The tests were performed on the operational graphics (on the more than 100 operational models created, we performed about 80 tests, including click tests, navigation tests and question tests with free-form answers);
