TRIZ for software architecture

A key element to designing software architectures of good quality is the systematic handling of contradicting quality requirements and the structuring principles that support them. The theory of inventive problem solving (TRIZ) by Altshuller offers tools that can be used to define such a systematic way. This paper describes the idea and preliminary results of using inventive principles and the contradiction matrix for the resolution of contradictions in the design of software architectures. By rearchitecting a flight simulation system these tools are analysed and their further development is proposed.
