“The collection does not primarily consist of GUI designs of common software, but tries to outline the recuring design problems faced when trying to create good design. Our method to produce good design is to use our Goal-Derived Design (GDD) method that is based on simulation of the userís goals. The pattern collection does not include all the characteristics of good design we know so far, but only the design knowledge that we have found appropriate to describe as design patterns.” (Sari A.
