Feedback is presented as an obvious tool for progress. A landmark meta-analysis nonetheless shows that one third of feedback interventions lower performance.

Matrix organisations promise flexibility and cross-expertise. Studies show the dual reporting line has a real cost, manageable under conditions.

Active listening is a commonplace in sales training. Yet studies do link it to trust and results, under specific conditions.
