It examines the theoretical development and application of the construct of Entrepreneurial Orientation's related scales over time, through an historical observation analysis. Theoretical foundations are traced, uncovering stages of development in purpose and application of EO scales. The study discusses level of analysis design and respondent perception factors unique to the setting of these scales. Empirical analysis examines level of analysis application associated with aspects of profiles, perceptions, and mechanics of respondents answering EO related measures. Several accepted scales are analyzed here in terms of respondent job position, profiles of change and control attributes, and levels of analysis. The scales are assessed for differences in terms of their theoretical development and application. Discussion and results are summarized suggesting a codified ecology for EO related measures, for education and research.enPh.D.
