    Key Findings • No standard restrictions / recommendations in terms

    of DRD layouting (cf. DMN 1.2) • Decision Tree layout is by far the most used • Directed acyclic graph • Standard way to reduce complexity → BKMs, Decision Services, Contexts, DRGs • Decisions should be modeled in stages (“Decision Flow”) • Snapping is a preferred way while helping layouting • Layout conventions could support understandability, but its not tested 4
