- Canterbury District Health Board Emergency Dept: within presenting heart attack patients, only 19% have a Major Adverse Cardiovascular Event (MACE). Significant resources are applied to this area, with many non-MACE patients having to stay overnight, constraining resources while Clinicians needed better decision support in the form of Machine Learning. He scoped the project, agreed on deliverables and selected and led two other Data Scientists. Using Machine Learning proved that it is possible to discharge patients presenting with Heart Attack symptoms earlier. From 34% within 3.5 hours to 52%, significantly saving resources and improved patient comfort. In addition, proven safe to discharge 36% of patients within 90 minutes using only 1 Troponin Test.
- Arrow/Southern Response Decision Room: Following the Christchurch Earthquakes in 2010/11 and significant delays in getting the Rebuild started, the Project Management Office was faced with ongoing protestors but uncertain of where the pain came from.

Implemented the KPI’s and task lists within personal scoreboards and the decision room, providing action lists for Project Managers. Successfully addressed critical issues, culminating in the Award for Arrow International ‘Innovation’- achieving significant increases in cross-pollination amongst staff, developing team culture, and a clear way forward to meet the December 2016 deadline to complete the Rebuild.
