Is it possible to bring the benefits of rigorous software engineering methodologies to end users? End users create software when they use spreadsheet systems, web authoring tools and graphical languages, when they write educational simulations, spreadsheets, and dynamic e-business web applications. Unfortunately, however, errors are pervasive in end-user software, and the resulting impact is sometimes enormous. A growing number of researchers and developers are working on ways to make the software created by end users more reliable. This workshop brings together researchers who are addressing this topic with industry representatives who are deploying end-user programming applications, to facilitate sharing of real-world problems and solutions.
