Too much data,
made clear.

I'm Grazia Prato, a product designer. For more than ten years I've designed the tools that telescope operators, transit controllers, arbitrators and mine inspectors decide with, from field research to the code.

Case studies

Five projects, written in depth: the research, the decisions and what changed.

  1. The ReCon arbitrators page: cases, rulings and days per stage, with each arbitrator ranked by performance. Names are blurred.

    ReCon

    Arbitration performance, made visible

    One monitoring tool replaced four systems and a set of spreadsheets for the people running Chile's domain disputes.

  2. The GESTIN billing dashboard prototype: billed this year against the target, the variance against plan, and a variance summary for the board.

    AC3E

    From a reporting form to a management intranet

    A research center's platform only reported upward. Interviews with six groups turned a form redesign into a management intranet, starting with a billing dashboard: projected vs actual, by area.

  3. The Cero Accidente planner: mines prioritised by region, each with the points that explain its rank, and the inspection scheduler.

    Cero Accidente

    An AI ranking inspectors could trust

    A model ranked 3,905 mines by risk; the design showed inspectors why each one ranked where it did.

  4. The L.O.V.E. M1M3 view: hundreds of mirror actuators coloured by force, with one actuator's details and live accelerations.

    L.O.V.E.

    A control room for a telescope still being built

    Four and a half years designing monitoring and control before the main user, the data or much of the hardware existed.

  5. The CMB dashboard: a dark map of Santiago with incidents and alerts, data layers on the left and indicators on the right.

    CMB

    One map for a city's buses

    Real-time monitoring for Santiago's bus control room, with semantic zoom and a history view for recurring events.

How I work

  • Learn the roomI learn the domain where the work happens, until I can speak its language.
  • Show the whyInterfaces that explain their numbers, so experts trust what they act on.
  • Design with engineersDevelopers in research sessions, and front-end code from me when it helps.
  • Prototype to decideWhen a decision depends on real data, I build it and test it, now with AI doing more of the building.

I do the thinking. AI does more of the building.

On AC3E and on this site, I wrote the specs and AI built from them. Here is where it helps, where it doesn't, and what I check.
