This article describes how the Neuman Systems Model (NSM) can be used in a two-step process to provide both the form and the function for interdisciplinary client care. The NSM proposes five dimensions of human experience as being necessary for a complete understanding of a client system. This article takes these five content areas—psychological, physiological, spiritual, developmental, and sociocultural—and extrapolates them to their respective disciplines (e.g. nursing, social work, religion, psychology, etc.) to create a comprehensive interdisciplinary model for client care. The NSM also provides a common language and conceptual paradigm, congruent with allied disciplines. A demonstration project incorporating the NSM in the formation and functioning of an interdisciplinary team is described.
