Efficacy evaluation of a leadership development assessment centre for managers
Abstract
This study evaluated the efficacy of a leadership development intervention using an assessment centre approach.
Participants were 72 managers and peer workers (50%) with a steel manufacturing organisation from the Gauteng
province of South Africa (females = 17% and males = 83%). A randomised group design was used to evaluate the
programme. The intervention involved a leadership development assessment centre which included simulations to
develop a leader. Pre-post intervention data were collected using the New Leadership Behaviour Inventory – Version 2
(LBI - 2). The results indicate that the leadership development intervention was effective in developing the key
competencies of a leader. The most significant increase was found between the pre- and post-test for the competency,
and articulating vision. Leaders should have a vision for themselves and the company and should share a dream and
direction which their subordinates and peers wish to share and follow.
