This roadmap published in December 2021 by the Centre for Data Ethics and Innovation (CDEI) is intended to help the UK to grow an effective and ethical artificial intelligence (AI) ecosystem. The first publication of its kind, the roadmap sets out the steps needed to grow a mature, world-class AI assurance industry. AI assurance services will become a key part of the toolkit available to ensure effective, pro-innovation governance of AI. The forthcoming White Paper on the governance and regulation of AI will highlight the role of assurance both as a market-based means of managing AI risks, and as a complement to regulation. This will empower industry to ensure that AI systems meet their regulatory obligations.  It is complemented by an extended version also held in the APAN resources hub - search for "extended ecosystem"
