AbstractTeam climate is a construct which easily fits with organisational diagnosis and R&D effectiveness and which has been found to be readily acceptable to team leaders. This paper briefly describes the construction and use of an organisation climate instrument which was developed as a diagnostic tool for team climate characteristics in R&D, and a springboard for initiating indepth discussions with R&O team leaders. A system of feedback was developed which comprised a computerized set of plots including (1) CLIMAP (Climate MAPping) intended to depict the individual and aggregate profiles of individual perceptions along relevant climate dimensions. (2) LOCMAT (LOCation MATrix) intended to portray in a matrix form, the location of members relative to each other regarding their perception of team climate and the extent of their agreement/disagreement therewith. The development and use of the instrument and its associated form of feedback is viewed as a potential method for increasing the awareness of team members, project managers and team leaders of their work environment, and as a useful tool for initiating planned change. To date, information has been collected from more than 300 scientific and technical personnel in R&D establishments; amongst these, more specific data have been collected in 18 teams. Implications for management and also for further research are discussed.
