The brief

Halo's platform did everything it was supposed to and took a two-hour onboarding session to learn. In a ward at three in the morning, on a shared machine, by someone covering a shift, that is the same as not working.

What we did

We ran the redesign inside two hospitals rather than in the studio. Eleven observed sessions on real shifts, watching where people hesitated and what they wrote on sticky notes attached to monitors.

Almost everything came down to one thing: the interface asked users to remember state. Which patient, which form, which step. So we made state visible — a persistent context bar, one primary action per screen, and destructive actions that are undoable rather than confirmed.

The back end is Laravel and it stayed Laravel. This was not a rewrite; it was a rebuild of everything above the controller layer, shipped behind a flag ward by ward.

How it landed

Time on the core task dropped 44%. Task completion without help went to 96%. Halo have not run a training session since — new staff are handed a login instead.

· How it ran

Start to live, in order.

The whole thing took 14 weeks, with Halo in the room for every phase.

  1. Weeks 1–3

    On the ward

    Eleven observed sessions across two hospitals, on real shifts including nights.

  2. Weeks 4–6

    Architecture

    Rebuilt the information architecture around making state visible.

  3. Weeks 6–12

    Design & build

    Screen by screen, behind a feature flag, with clinicians reviewing weekly.

  4. Weeks 13–14

    Rollout

    Ward by ward, with the old interface one click away for a month.

What Halo said

Rare to find a studio that is this strong on both design and engineering. No translation loss between the two.
