This paper explores the relevance of a psychoanalytic understanding of
unconscious processes in groups and Wilfred Bion's concept of ''basic
assumptions'' to the processes in multidisciplinary teams. Such teams
often fail to define their purpose, structure and member roles in a s
ufficiently clear way. Consequently they are easily overwhelmed by bas
ic assumption mentality which impedes their work. The team and each me
mber remain in an unresolved conflict about whether or not to become a
team. The paper goes on to summarise some factors crucial to effectiv
e team functioning.
