The cornerstone of project success
Requirements management, requirements definition, and requirements engineering practices are the cornerstones of project success. In a recent industry study, organizations surveyed incurred a cost of as much as 60 percent on time and budget when they used poor requirements management practices. Organizations with poor business analysis capabilities had three times as many project failures as successes. With proper requirements management and definition, organizations can reduce project overruns by as much as 20 percent by limiting the number of inaccurate, incomplete, and omitted requirements.
