Projects are executed by people. Human resource management (HRM) processes are required to make the most effective use of the people in a project environment in order for organizations to be competitive. Project orientated organizations (POO) have specific characteristics which have special requirements in terms of an organization's HRM processes as opposed to those processes employed by classically managed organizations. In this study, the focus group technique was used to explore and understand the HRM processes employed by the mature POO with a specific focus on their requirements and dependencies. The study was conducted within one of the leading information and communications technology (ICT) companies in South Africa. The organizational strategy is the driver of the HRM processes in the mature POO. POOs spend a significant amount of time and resources to hire new employees. It is therefore important that the right resources are appointed. The research results identified that the HR planning and recruiting processes are the key processes in the mature POO. The research further identified the differences in sources of information required by the human resource (HR) planning processes of organizations executing internal projects as opposed to external projects.
