This study is an evaluation of the developmental needs of business leaders. Altogether, 190 leaders, representing 22 nationalities, participated in 12 four-day training sessions. The first aim of this study was to identify the key developmental concerns of leaders; the second was to determine what kinds of training methods the leaders preferred; and the third was to design a form that could be used for further training. Fourteen developmental areas were identified. The key areas that needed development were related to Interaction, Coaching, Giving and Receiving Feedback, and Everyday Work Skills. Artificial experience building and tailor-made training were preferred over lecturing. In further training, activating methods need to be used and demographics taken into consideration.
