The model was also applied in several other countries.
Agencies range from Her Majesty's Prison Service to the Driver and Vehicle Licensing Agency. The annual budget for each agency, allocated by Her Majesty's Treasury ranges from a few million pounds for the smallest agencies to £700m for the Court Service. Virtually all government departments have at least one agency.

Its main goal was to identify what good practices had emerged from the new model and spread them to other agencies and departments. The report also recommended further powers be devolved from ministers to chief executives.

During these the agency model became the standard model for delivering public services in the United Kingdom. By 1997 76% of civil servants were employed by an agency. The new Labour government in its first such report – the 1998 Next Steps Report endorsed the model introduced by its predecessor. The most recent review (in 2002, linked below) made two central conclusions (their emphasis):
