This book is both a completed endeavor and a work in progress. It is unquestionable that leaders must develop technical, socio-relational, cognitive and self-leadership competencies. It is also indisputable that the relative importance of these competencies changes as leaders advance in their careers. However, the thesis that leadership is a process involving leaders, followers and the situation has an implication: as followers and the situation change (and few changes are as profound as those engendered by COVID-19), leaders must adapt their behaviors in order to be more effective leaders. Thus, here it is another implication: leadership itself is also a work in progress.
