Abstract

Defects are seen as lack of product quality. Defects represent a loss in economy which increases with the amount of defects. On the other hand, costs to avoid defects increase if the accepted amount of defects is reduced. Consequently, an optimal amount of defects may be stipulated. In building projects, the optimal amount of defects is considered as a balance that every player seeks to achieve. This paper includes the development of a qualitative model for dealing with optimization of the amount of defects and the associated quality cost. The parameters that influences the dynamic optimization processes in real building projects are explored. It is concluded that the model is useful to form heuristics concerning quality cost and that such heuristics shall aim at minimizing the quality cost rather than the amount of defects. The paper is based on a part of a larger research project 'Defects in construction: strategies, actions and learning'.
