According to Sir Allen Shepherd what is the task of corporate leadership?

According to Sir Allen Shepherd to apply energy and judgement to the corporate culture to ensure its relevance is the task of corporate leadership. Shepherd leadership is a matter of selfless service to subordinates. This service to others will require a commitment to serve without the potential of immediate recognition or reward. Shepherd leadership will require, at times, gently leading those in their charge, mentoring and sometimes teaching them along the way.
