This workshop is an invited working meeting for the members of the Program Committe of the International Symposium on Requirements Engineering and for the members of the Steering Committe of the International Symposium on Requirements Engineering and of the International Conference on Requirements Engineering.

It is a discussion-oriented workshop with sessions devoted to the following four topics:

• Problem frames in requirements engineering
• Software requirements and systems engineering
• Abstraction levels in requirements engineering
• Natural language and requirements engineering

Each session starts with two invited speakers who give a position statement or a short talk. Then there will be an open discussion, both on the talks and on other issues belonging to the topic of the session.
