Commentary by Dr. Whitesel: This Harvard Business Review article cited research that managers who are stable and mature (i.e. typically thought of as ‘boring’) are the best middle managers. And, it points out that everyone as they mature becomes better at these attributes (I know I have). But it also supports something I’ve been saying for many years: that we often promote operational (i.e. relational) leaders into middle-manager roles. Such operational leaders are more attuned to one on one leadership and less attune to manage and develop the complex matrix of organizational behavior. For more on strategic – tactical – operational (STO) leadership see these articles. Then read this HBR article for verification and additional ideas.
