Formulation is a process of developing an understanding of what is happening for a person and why, and therefore what might be helpful for them. It involves gathering information, drawing from personal meanings and theoretical understandings to develop a coherent narrative. Traditionally, formulation is undertaken by a practitioner and a service user on an individual basis, but it can also be undertaken in a team context.

This article explores team formulation, outlining its ideas, implementation and potential effects. It describes some of the evidence, outlines some techniques that can be used and reflects on team formulation in practice. However, it is not a systematic review of the evidence. It is hoped that this process will enable readers to develop an enhanced awareness of the concepts and issues involved, feel more confident engaging in team formulation and recognise the challenges and value that it can bring to clinical practice.
