Studies examined a range of aspects of healthcare, from ward management and operating theatres to the organisation of cleaning staff. More recently, the institute has conducted work for the European Commission and British government bodies. Research units In the institute's early years, there were four main units: Programme Groups A and B within a Committee on Human Resources; Organisation and Social Change and Operations Research Unit; and a Committee on Family and Community Psychiatry. The Human Resources Centre (HRC) and the Centre for Applied Social Research (CASR) were established in the 1950s, and in 1963 the Institute of Operational Research (IOR) was established in conjunction with the British Operational Research Society.

Although he died before the TIHR was formally established, Kurt Lewin was an important influence on the work of the Tavistock: he was a notable influence on Trist, and contributed an article to the first issue of Human Relations. Many of the members of the Tavistock Institute went on to play major roles in psychology. John Rawlings Rees became first president of the World Federation for Mental Health. Jock Sutherland became director of the new post-war Tavistock Clinic, when it was incorporated into the newly established British National Health Service in 1946. Ronald Hargreaves became deputy director of the World Health Organization. Tommy Wilson became chairman of the Tavistock Institute. One of the most influential figures to emerge from the institute was the psychoanalyst Isabel Menzies Lyth. Her seminal paper 'A case study in the functioning of social systems as a defence against anxiety' (1959) inspired a whole branch of
