This paper describes a process used by Shell Business Consultancy to model manpower in an IT department. The IT world has been undergoing rapid changes in the last decade due to a highly mobile job market, skill shortages and the widespread use of contractors. Given these problems, it is important that management understand the implications of personnel policies. Shell Business Consultants built a STELLA model with the managers involved to focus their attention on the key issues and to enable them to actively explore policy options. The paper focuses on the process used in this project and combines it with our other experience to draw some generally applicable lessons that should be of use to all practitioners.
