Feedback is a critical part of the design process. Every designer works with key stakeholders, such as clients, users, and developers, who contribute information needed for a project’s success. This thesis presents interviews with 18 expert designers to gather their perspective on design feedback. Using the phenomenological qualitative research method, data from interviews were clustered into themes. Firstly, four feedback roles in the professional design setting were identified: (1) determining a project’s true goals, (2) collaboratively improving the design, (3) strengthening business relationships, and (4) securing project payments. Secondly, feedback was categorized into four types: reactive, evaluative, explorative, and prescriptive feedback. Thirdly, participant preferences on feedback were discovered to depend on who provided the feedback, how the feedback was acquired, and when designers received the feedback. These led to the development of a new framework outlining expert feedback preferences throughout a 5-stage design process.
