AbstractDesigners formulate requirements to ensure development processes that anticipate stakeholder needs. Most development projects fail due to vague and imprecisely formulated requirements, which is linked to poor requirement quality in the early phases of development projects.This paper presents the newly developed REQ Method to systematically support designers during the formulation of requirements, according to important quality criteria. The paper offers a critically reflected assessment scheme for documented requirements to assess requirement quality. The methodological support builds a valuable base for better requirement quality, reducing the risk of trade-offs and project termination.
