This paper presents how the use of simulation can provide benefits to learn project business in nowadays world’s complex context. This last decade, due to the fast technological advances and the rising globalization, markets are becoming more and more competitive, and this drives companies to increase their interest in planning and implementing specific projects, as they strive to achieve corporate goals. This resulted on various standards emerging around project management and an increase in the degree of professionalism. However, projects still continue to fail due to the increasing complexity of the projects or an underestimation of the projects complexity. The aim of the framework is to presents after a literature review, what a project business is, what complexity means in this context, and how simulation can help to avoid the gaps of nowadays. With this information a proper simulation model is designed using the software Anylogic. The model is based in a project process network and it’s mainly focused on buffers allocation, resources, quality, budget and time management. Once the model was done has been validated in a workshop through a form the participants filled after interacting with the software and the models. With that feedback it has been possible to evaluate how students feel about using simulation as a teaching tool and show how the literature references were right and closely connected with the results obtained.
