The chapter offers accounts by seven different teams trained and working in AMBIT-influenced ways, illustrating a variety of settings, the ways in which AMBIT has helped to improve their practice, and the challenges they faced. The chapter starts with an analogy comparing AMBIT with the operating system of a computer, which may run multiple different types of programs to address specific issues. The seven teams are: (i) an intensive CAMHS adolescent outreach service in London, designed to reduce inpatient admissions, (ii) a Tier 4 specialist adolescent inpatient unit in East Anglia, managing high risk/highly challenging behaviors, (iii) a voluntary sector outreach team working in London with highly excluded and gang-related young people, (iv) a therapeutic residential community for children with severe disturbance in the USA, (v) an intensive CAMHS community treatment service in Scotland, (vi) a service for young people on the edge of care in London, and (vii) a young people’s substance use service in a mixed urban/rural setting in the UK.
