Comgy provides energy data for buildings. Property managers got lost during a routine tenant change, so I rebuilt that flow around one obvious action.
Managers need to keep data up to date and send tenants consumption information. Across many apartments it was easy to get lost: it wasn't clear whether to edit the current tenant or add a new one, and installer abbreviations were mixed with manager actions.
With the product manager I reviewed the existing solution and user reports. I wrote a simple persona, a problem canvas and user stories, then compared the old and new flows on a real task: move a tenant out of a specific apartment.
The apartment level got a primary "Change tenant" button. Users no longer need to remember whether it's a move-in or a move-out, because the system picks the right form.
The wizard hides questions that don't apply to the process and shows important values as read-only. Finishing a move-out no longer forces you to add the next tenant, and the notification says who replaced whom.
Beyond the flow itself, we introduced UX standards such as user flows and user tests. Working with a different team every six weeks also taught me to adapt quickly to new requirements.
