Traditional learning methods in operations management are not ideally suited for externalising knowledge. In this paper, an iterative, gaming-like learning approach for practicing OM issues by using discrete event simulation model is proposed. The approach is utilising an existing learning environment called Delfoi Planner EDU. Its web-based architecture supports distance learning that is an asset in the Finnish University culture. The article also describes the current learning content. The environment enables adding new tasks and exercises easily and is designed to support 3rd party simulation models thereby facilitating learning content exchange between content producers. The initial evaluation with a pilot class suggest that the benefits of gaming have been realised but also underlines the importance of a tested, stable environment as a prerequisite for learning.
