This report covers the period from 1993 when the CREST project was initiated, to its launch in 1996, and considers the environment that prompted its instigation. The report looks at the massive cooperation of Government, industry and a range of different service providers that all came together, under the central control of the CREST project team. It proposes five reasons why the CREST project was successful and examines why the CREST system continues to be at the heart of UK settlement, 20 years on.
