Design theory and practice.

Abstract: "This paper is Part II of a study advocating the use of the scientific method for conducting design research. Part I critically reviewed General Design Theory (GDT) -- a formal theory of design -- and discussed its influence on the construction of design support systems. This part presents an experimental system built based on the guidelines set by GDT. It evaluates the experimental system and comparesthe theory and the experimental approaches. The comparison generates recommendations for enhancements of the experimental system and refinements to the theory. These recommendations complete a single, successful scientific cycle of this research. The recommendations that are grounded in testings show the benefits from subscribing to the scientific method of conducting design research."
