The assertive community treatment team as a complex dynamic system of care

This paper presents a dynamic systems view of assertive community treatment (ACT), a recognized evidence-based treatment for adults with severe and persistent mental illness (SPMI). It is argued that because an ACT team operates as a complex adaptive system (CAS), it engages in the organizational processes of "sensemaking" and self-organization, which help to bring order to the actions of team members and sustainability of the intervention itself. Consequently, successful implementation of ACT requires that management technologies Such as meaning-creation and design are used in conjunction with traditional "command and control" technologies of policies, procedures, processes, and structures.
