Janet E. Burge is an Assistant Professor at Miami University Computer Science and Systems Analysis Department. Her major research interests are in Software Engineering and Artificial Intelligence. Her primary research area is in Design Rationale, with a focus on Design Rationale for Software Maintenance. She received her PhD in Computer Science from WPI in 2005, her M.S in Computer Science from WPI in 1999, and her B.S. in Computer Science from Michigan Technological University in 1984. John M. Carroll is the Edward M. Frymoyer Chair Professor of Information Sciences and Technology at the Pennsylvania State University. His research interests include methods and theory in human-computer interaction, particularly as applied to networking tools for collaborative learning and problem solving, and the design of interactive information systems. He serves on several editorial boards for journals, handbooks, and series and is Editor-in-Chief of the ACM Transactions on Computer-Human Interactions. He received the Rigo Award and the CHI Lifetime Achievement Award from ACM, the Silver Core Award from IFIP, and the Alfred N. Goldsmith Award from IEEE. He is a fellow of the ACM, IEEE, and HFES. Raymond McCall is an Associate Professor in the Department of Planning and Design at the University of Colorado, Denver. His major areas of research are in design rationale methods and systems. Since 1992, most of his research has concentrated on the use of rationale to support the design of artifacts for human exploration of space. For much of this time he collaborated with NASA contractors and with employees of the Johnson Space Center in Houston. He has nearly 30 years of experience in design rationale usage in architectural design, planning, policy making and software design. He created the first hypertext systems for support of design rationale in the 1970s and 1980s and was the first to integrate support for rationale capture and delivery into 3D computer-aided design systems. Ivan Mistri-k is an independent consultant for software-intensive systems engineering. He has 40 years experience in both software and systems engineering as an information systems developer, R&D leader, research analyst, and ICT management consultant. He is the author or co-author of more than 80 articles and papers in international journals, conferences, books and workshops and was an editor of the Special Issue on "Relating Software Requirements and Architectures" published in 2005.
