In 2001, he decided to put his theory into practice. Mike assembled a team to develop an analytics engine for selecting candidates based on the actual determinants of high performance. In order to test this engine, Mike used it to build a technology company, Catalyst DevWorks, which has since proven his theory, realizing substantial growth, garnering press from the likes of the Wall Street Journal and CIO magazine, praise from analysts and experts in IT including the leading analyst firm Gartner, and client accolades from organizations including Nike and L’Oreal. By 2009, enough data and results had been collected to deploy this engine – Arena - more broadly. Armed with this proof, Arena teamed up with Shady Grove Adventist Hospital. The goal was 20% turnover reduction. In fact, turnover decreased by 58%. After the Arena algorithms had an opportunity to learn, this improvement increased to 77%.
