1. Effective Design Rationale: Understanding the John Horner & Michael E. Atwood

Summary: 1. Effective Design Rationale: Understanding the
John Horner & Michael E. Atwood
One goal of design rationale systems is to support designers by
providing a means to record and communicate the argumenta-
tion and reasoning behind the design process. However, there
are several inherent limitations to developing systems that effec-
tively capture and utilize design rationale. The dynamic and
contextual nature of design and our inability to exhaustively
analyze all possible design issues results in cognitive, capture,
retrieval, and usage limitations. In this chapter we analyze these
issues in terms of current perspectives in design theory, and de-
scribe the implications to design research. We discuss the barri-
ers to effective design rationale in terms of three major goals: re-
flection, communication, and analysis of design processes. We
then suggest alternate means to achieve these goals that can be
used with or instead of design rationale systems.
1.1. Introduction
Design is a goal-oriented process aimed at solving problems, meeting
needs, improving situations, or creating something new or useful [9] . De-
