Deals with theoretical arguments that justify why the leadership of managers and its ethical dimension is a powerful enabler for TQM efforts to sustain, together with a systematic management. Starts by setting out a multidimensional conception of leadership in which the ethical sphere is explicitly considered. The principles articulating TQM are then analysed, studying the role of leadership and its ethical dimension, in their implementation. Concludes with five propositions, stating that the explicit consideration of leadershipÂs ethical dimension is required in order to achieve a complete, deep and sustained deployment of TQM principles. Draws implications for managers and researchers.
