Bio
Stefan Biffl is an associate professor of software engineering at the Institute of Software Technology and Interactive Systems, Technische Universität Wien.
He received MS and PhD degrees in computer science from the Vienna University of Technology and an MS degree in social and economic sciences from the University of Vienna. In 2001 Stefan received an Erwin-Schrödinger research scholarship and spent one year as researcher at the Fraunhofer Institute of Experimental Software Engineering (headed by Dieter Rombach), focusing on quality management and empirical software engineering. Also, in 2001 he received the Habilitation degree (Venia Docendi) in “Praktische Informatik” for work on empirical software engineering in project management and quality management. In 2006 he worked as guest researcher at Czech Technical University, Department of Cybernetics (headed by Vladimir Marik).

In this paper we report on an empirical study that compares the performance of two techniques to visualize task relationships and temporal uncertainties: traditional ``best-practice'' PERT charts and recently introduced PlanningLines. Main results of the study are: (a) while PERT charts are well suited for reading single attributes, PlanningLines better support users in judging temporal task uncertainty; (b) both experiment rounds shows consistent results regarding the strengths and limitations of the techniques. Overall, these results suggest that a combination of PERT charts and PlanningLines has the potential to significantly improve the planning support of project managers and software engineers.},
