The Project Management Institute have recognised the connection between project management and requirements. In May 2014 they published a report “Pulse of the Profession, Requirements Management: A core competency for Project and Program Success”.
Among other interesting findings, the study revealed that “inaccurate requirements gathering” remained a primary cause of project failure (37 percent) in 2014 (up from 32 percent in 2013). The places where organisations are typically falling short are: People (skills and resources), Process (not having a consistent one), Culture (not having enough value put on requirements at the top of the organisation).
