The more complex a software system is and the longer a software system evolves, the more difficult it is to avoid effects like software architecture erosion or architectural drifts. These effects can lead to systems where the realization of the system diverges from the intended architecture with resultant negative impacts on quality attributes associated with the intended architecture. As studies have shown, untreated divergence can lead to systems which are impossible to maintain in the long run. SAEroCon is dedicated to research related to these phenomena.
