Motivation

How to best leverage ICT to couple and engage end-user and OSS

developer communities in requirements negotiation?

Challenges

Traditional Requirements Engineering (RE) techniques do not scale

Existing ICT tools for RE often daunting for end-users/incomplete for developers

Innovative end-user ideas seldomly reach OSS developers
