Object-oriented design principles are fundamental concepts that foster the development of software-intensive systems with a focus on good design quality. The aim of this paper is to examine the relationship between design best practices and 10 selected design principles. This should provide evidence whether the key design aspects of the design principles are covered. We conducted focus group research with six focus groups and 31 participants in total. Each group discussed five design principles and assessed the coverage by using the Delphi method. The result reveals the impact of each design best practice to the design principle and shows that the main design aspects of the design principles are covered by our approach.
