Ella Worsdale's NHS team was sending out reports that were out of date the moment they landed, and nobody trusted the numbers. So she ran a Tableau pilot in front of managers who said they were not interested, sat them down with dashboards tied to their own work and watched them take ownership. That pilot unlocked funding for a rollout that reached around 700 people. She is candid about the funding fight, moving a team of 20 from SQL and Excel into Tableau, and handing over before her leave.
