In this paper, we present evidence on the measurement properties of an instrument that assesses six dimensions of organizational strategy development. These dimensions are labelled planning, incrementalism, cultural, political, command and enforced choice. Using data from 5332 managers, results indicate the instrument has acceptable reliability and validity. Exploratory factor analysis confirms its underlying structure. Generally, the sub-scales have acceptable internal reliability and inter-rater reliability at the organizational level (n = 770 organizations). Further, using data aggregated at the organizational level, the sub-scales are judged to have acceptable validity from the pattern of correlations amongst the six dimensions and with other variables.
