Poor requirements cause many project problems. Some traditional approaches write voluminous requirements that too often don’t help much and may even contribute to difficulties. Agile instead writes brief three-line user stories. Yet, many have as much if not more difficulty writing Agile’s brief requirements effectively. This interactive workshop reveals reasons requirements, especially Agile user stories, can fall short, explains critical concepts needed for effectiveness, and uses a real case to provide participants guided practice writing and evaluating traditional requirements and Agile user stories.
