The Overall Managerial Readiness (OMR) scale was first developed as a simple measure of managerial potential for the Chinese workforce. OMR purports to predict managerial performance by assessing a person's attitudes and intention to engage in managerial practices. It consists of 28 forced-choice statements most of which refer to attitudes and behaviors in a work setting. Three studies together showed that OMR was correlated negatively with neuroticism, and positively with conscientiousness, agreeableness, openness to experience, and extraversion. Notwithstanding, OMR was distinct from the Big Five, and had incremental predictive power on work performance (Study 3). Besides, OMR alone predicted bank managers' productivity (Study 4). Finally, internal consistency and concurrent validity of a Likert version of OMR was ascertained (Study 5).
