Organizational improvisation is increasingly recognized as a relevant area of management research. However, the cumulativeness of research on improvisation in organizations remains low. This paper organizes existing contributions on organizational improvisation within a new consolidating framework combining degrees (minor, bounded and structural) and levels (individual, interpersonal and organizational) of improvisation. The proposed degree/level framework allows for reviewing the existing literature on organizational improvisation in the management disciplines of strategy, organizational behaviour, organizational theory, innovation and marketing in a systematic manner. It also exposes potential areas for future research across management disciplines, research areas, organizational settings and industries, and beyond existing metaphors, most notably of jazz and improvisational theatre.
