Organizational innovativeness (OI) is a central concept in academic research and managerial practice. In many cases, OI has been operationalized as the number of innovations organizations adopt. In contrast, this paper conceptualizes OI as a five-dimensional construct (creativity, openness, future orientation, risk-taking, and proactiveness) representing the organizational climate, which refers to the organization's ability to generate ideas and innovate continually over time. The findings support the conceptualization and operationalization of the five-dimensional OI, validated in Norway, Israel, and Spain. These results shed new light on existing findings and can promote new research directions as well as guide strategic managerial decision-making.
