Welcome to the Summer 2011 edition of the PPIG newsletter.

Quite a lot of time has passed since the last issue and quite a lot has happened too. It's not possible to write about all the events and publications that have occurred and emerged between 2009 and 2011, but I do hope that what you find within this newsletter is both interesting and informative.

This issue begins with some useful information for the forthcoming 2011 workshop, which is to be held in the University of York, UK, in September. This is followed with a report from both the most recent work in progress (WIP), and main PPIG workshop. Jennifer Ferreira from the Open University has written a trip report for the 8th International Advanced School in Empirical Software Engineering.

This issue contains two short articles, one by Fabian Fagerholm. The articles are followed by a short resource section and then to two familiar columns: the spotlight on PPIG members section, and a suitably random collection of assorted links.

I hope you enjoy this somewhat belated issue of the PPIG newsletter. As always, if you have any ideas or suggestions, please don't hesitate to get in touch. I'll always be happy to hear from you.
