Following a lively discussion at the AEDS-SIG Workshop 2005, I had the pleasure of reading the doctoral thesis by Kalevi Nevala [2005a]. The following is a summary and interpretation of comments I made to Dr. Nevala. In discussions or considerations of design engineering problems and engineering designers, different words are often used. Designing is a process of transforming information about a future technical process and/or technical system, performed by iterative interacting between external representations and mental models. My comments are based on the pioneering work of Vladimir Hubka [1974, 1976, 1978, 1982, 1984, 1988a, 1988b, 1992 and 1996] with additions [Eder 1992, 1996 and 2008].
