This study reports on an approach for assessing managerial development needs. The approach uses multi-methods such as qualitative career plots, critical incidents, a skill rating form, and surveys to identify the critical managerial development needs for a target managerial position. In addition, it uses multi-subject groups in an effort to triangulate on the development needs. The empirical findings indicate that, through this approach, congruent managerial development needs can be identified. By doing so, the organization can design a systematic development effort that will enable them to have both effective managers when they need them in an efficient manner. (Contains 6 tables.)
