The Matrix Arrange a walkthroughWalkthrough

A good roster is
a systems problem.

ICU rostering that connects coverage, recovery and real lives.

The complexity
behind the roster.

Coverage. Recovery. Fairness.
Every decision is connected.

Part of the unit’s safety system.

The right experience

The right mix on each shift.

Recovery after nights

Space around demanding work.

Requests and fair shares

Individual needs, kept in view.

Fictional example

This is a lot for one person to hold in their head.

The people
who live with it.

A life outside the hospital.
A team that feels cared for.

Requested off. Still rostered.

Fortnight example; full-term context matters.

Change a shift.

Developed and used in an Australian ICU.
How Matrix is built

AI-assisted development. Mathematical constraint optimisation to build rosters around the unit’s requirements and priorities.
