This paper explores how different occurrences come to deﬁne the progression and perception of design processes. We turn to the notion of a design event, which is often used to describe speciﬁc occurrences in the design process, and to highlight moments of interest. However, the term seems to have no clear origin or agree-upon deﬁnition. In order to qualify the term, we provide a working deﬁnition using two different methods: First, a comprehensive review of the literature engaging with the term. This indicates that design events are somewhat equal to workshops, but with additional nuances. Second, interviews with design practitioners on types of design events and how they deﬁne their work. We present a basic typology of design events and provide detailed accounts of their characteristics. The difference between design events described in literature and design events disclosed by the practitioners are discussed. We conclude with a working deﬁnition.
