In this episode, Warwick shared how data science is applied in government to help with meeting business outcomes. This includes, but not limited to, some of the special task forces setup at the ATO to combat the black economy and serious non-compliance. We also exchanged views on the future of a cashless economy and how it has the potential to increase revenue collection. In addition to the above, he also discussed the use of statistical techniques to identify different classes in the community such as different types of medical practitioners. One point he emphasized is how important it is for organizations, especially governments, to ‘dig the eyes’ out of data in order to improve decision making, to develop effective policies and programs and to deliver services to the community.
