BA Brew 34: Non-Functional Requirements (Feat. Steve Wright) Fuelled by freshly made coffee, Steve Wright and the Brew Crew discuss the difference between functional and non-functional requirements; why it pays to have non-functional requirements on the agenda from the start; the joy of checklists and more. During the chat Pete Thompson recommends the book by Software Requirements Patterns by Stephen Withall, for its useful contextual checklists.
