The Home Office's ACE team solve public safety challenges from data and digital technology, at the pace demanded by a fast-changing world. ACE challenged conventional problem-solving, introducing agile, collaborative ways of working that accelerate solution-finding from years to months or weeks. This imaginative, entrepreneurial team found a new, cost-effective way to drive start-ups, SMEs, the not-for-profit sector and academia to bring cutting-edge expertise to bear on these challenges. The team won the Institute for Collaborative Working's 2019 innovation award, and the Massachusetts Institute of Technology cited ACE as an effective model which should be replicated across government.
