To measure object-oriented design quality, metric-based approaches have been established. These have then been enhanced by identifying design smells in code. While these approaches are useful for identifying hot spots that should be refactored, they are still too vague to sufficiently guide software developers to implement improvements. This is why our work focuses on measuring the compliance of source code with object-oriented design best practices. These design best practices were systematically derived from the literature and can be mapped to design principles, which can help reveal fundamental object-oriented design issues in a software product. Despite the successful applications of this approach in industrial and open source projects, there is little accepted knowledge about the importance of various design best practices. Consequently, this paper shows the result of an online survey aimed at identifying the importance of 49 design best practices on design quality. In total, 214 people participated in the survey, resulting in an average of 138 opinions for each practice. Based on these opinions, five very important, 21 important, 12 moderately important and 11 unimportant design best practices could be derived. This information about importance helps managing design improvements in a focused way.
