Impact of software design patterns on the quality of software: A comparative study

The quality of software systems depends on several factors and one of them is how the software architects use the design patterns in the design of softwares. This paper comprehensively surveys the existing software design patterns available. The study has two fold objectives. The first and foremost objective is to evaluate the design patterns in terms of their design and quality attributes. The second objective is to provide a summary as how these design patterns affect the software quality. The literature reveals that only four quality attributes of design patterns have been investigated and there is no consensus available on their impact.
