This volume collects the descriptions of the demonstrations that were presented at the 13th International Conference on Business Process Management (BPM), which was held from August 31st to September 3rd, 2015, in Innsbruck, Austria. The conference brings together researchers and practitioners alike and represents one of the most prestigious scienti c events on BPM worldwide. BPM is an area of research that is strongly intertwined with practice, and the demonstration track assumes a major role in the program of the conference. It allows everybody to showcase novel software solutions related to the topics of the conference, ranging, for example, from process modeling tools for end{users to low{level process mining algorithms running hidden in a back{o ce or in the cloud. This year we got an exceptional number of 40 submissions of demonstration proposals. While, on the one hand, this is an extraordinary result, on the other hand, it also meant that we had to carefully select the proposals with the help of the PC of the Demo track. Unfortunately, space and equipment are limited, and we could not accommodate everybody. In the end, 28 demonstrations were selected for presentation and are printed in this volume. We are proud about the nal demo program of this year's edition of the conference, which we believe is of very high quality, and we are con dent that it contains something interesting for everybody working on BPM and related topics. We would like the thank everybody who contributed to the demo program: the authors, the PC members, and of course the organizers of the conference. It was a pleasure working with you.
