OR groups have been studied from several perspectives and increasingly
their role as a means of organising OR work is seen to be subject to
a variety of external influences. In this paper OR groups are examined
as a form of arranging professional work in organisations using an an
alytic framework based on concepts from the sociology of professions.
The changing character and fortune of such groups is shown to be relat
ed to processes involved with the professional character of OR. The ro
le of education, changing organisational contexts, the emergence of ot
her professions and the ability of OR to respond to these are all key
factors in explaining the development of OR groups. Issues of relevanc
e to the future of OR groups arising from this analysis are finally co
nsidered.
