SharePoint

The problem

The Secretariat's existing intranet, built on SharePoint, was essentially a compiled folder structure — navigable only if you already knew exactly where what you needed was located. Everyday services were scattered across separate links employees had to remember individually, and Secretariat updates that people cared about lived only on social media, invisible internally.

Why it changed

These were long-standing complaints from employees, and they're what triggered the restructuring. Research conducted jointly by the IT and Communications teams confirmed what needed fixing and helped shape what each department actually needed to see, rather than just surfacing every file that existed.


What I did

I designed and built the new navigation and visual identity from the ground up, working within SharePoint's real design constraints. The new structure consolidated scattered services into a single, findable place, and gave Secretariat updates a proper home inside the intranet instead of only on social media.

Result

Within its first month live, the platform recorded 3,966 visits and 41,446 actions. The three most-used services were exactly the ones employees used to struggle to find: IT support requests, the staff directory, and the department abbreviations glossary. What used to require remembering a scattered link or asking a coworker became a two-click search.

IT reported a smoother flow of demands, since employees now knew exactly where to submit requests. HR gained a way to reach individual teams directly, instead of sending documents to everyone at once. Communications introduced request forms for design pieces, campaigns, and content, a process that didn't exist before.

Let's talk about inclusive design!
