This book constitutes the refereed proceedings of the 6th International Symposium on End-User Development, IS-EUD 2017, held in Eindhoven, The Netherlands, in June 2017.

The 10 full papers and 3 short papers presented were carefully reviewed and selected from 26 submissions. According to the theme of the conference "that was business, this is personal" the papers address the personal involvement and engagement of end-users, the application of end-user programming beyond the professional environment looking also at discretionary use of technologies. They also deal with topics covered by the broader area of end-user development such as domain specific tools, spreadsheets, and end user aspects.
