Developers’ design decisions shape software and determine its ability to meet its requirements. Design smells also known as Antipatterns are “poor” solutions to recurring design problems. They are generally introduced in systems by developers who do not have sufficient knowledge and/or experience in solving a particular problem or who have misapplied some design patterns. Understanding and assessing the impact of developers’ design decisions on software quality poses several challenges. In this talk, I will report about a series of studies that we have conducted over the years to assess the impact of developers’ design decisions on software quality. I will also share some of the lessons that I have learned as a researcher while designing and running these studies. I will conclude my talk by presenting some of the research directions that we are currently investigating in my research team.
