A crucial part of project management research is the validation and extension of research ideas and methodologies proposed in the literature. The focus can lie on one of the following three themes (or a combination). First, resource-constrained project scheduling and its extensions are investigated widely in the literature. There is an increasing interest to collect and analyse data about project schedules with flexibility, multi-skilled workforces, project portfolios, etc. Also, schedule risk analysis requires detailed risk information on the activity level as well as data about external risk factors affecting the final project duration and cost. Techniques such as reference class forecasting help in assessing the impact of these risks on the project outcome. Finally, project control is traditionally done using Earned Value Management methodologies. In recent years, techniques such as tolerance limits for project control and corrective actions received increased attention.
