   ABSTRACT     = {Software engineers are creators of habits. During 
      software development, they follow again and again the same patterns 
      when architecting, designing and implementing programs. Alexander 
      introduced such patterns in architecture in 1974 and, 20 years later, 
      they made their way in software development thanks to the work of 
      Gamma et al. Software design patterns were promoted to make the 
      design of programs more ``flexible, modular, reusable, and 
      understandable''. However, ten years later, these patterns, their 
      roles, and their impact on software quality were not fully 
      understood. We then set out to study the impact of design patterns on 
      different quality attributes and published a paper entitled ``Do 
      Design Patterns Impact Software Quality Positively?'' in the 
      proceedings of the 12<sup>{th}</sup> European Conference on Software 
      Maintenance and Reengineering (CSMR) in 2008. Ten years later, this 
      paper received the Most Influential Paper award at the 
      25<sup>{th}</sup> International Conference on Software Analysis, 
      Evolution, and Reengineering (SANER) in 2018. In this retrospective 
      paper for the award, we report and reflect on our and others' studies 
      on the impact of design patterns, discussing some key findings 
      reported about design patterns. We also take a step back from these 
      studies and re-examine the role that design patterns should play in 
      software development. Finally, we outline some avenues for future 
      research work on design patterns, e.g., the identification of the 
      patterns really used by developers, the theories explaining the 
      impact of patterns, or their use to raise the abstraction level of 
      programming languages.}
