Execution is hardly a sole activity. It embraces talents and efforts of team members to get things done. When things get done, the credit should be ascribed to all team members, instead of the leader alone.
Equally, when execution fails to deliver the right result, the focus should be on finding out what went wrong instead of who did wrong. The question of who did wrong will lead to blame, name calling and isolation of group approach to providing solutions in a tensed atmosphere.
Execution leaders must be forth coming with praise, appreciation, recognition and commendation for employees who have truly earn them at the appropriate time and place. To ascribe a group achievement to oneself because the person was a leader of the team is the shortest way of killing resourcefulness, individual contribution and collaborative efforts of team members during execution.
