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% on time and budget when they used poor requirements practices. Organizations with poor business analysis capabilities had three times as many project failures as successes.
When requirements are defined and managed properly, project overruns can be reduced by as much as 20% by reducing the number of inaccurate, incomplete, and omitted requirements.

- Reduce rework and accelerate time to market by collaborating with your stakeholders
- Increase productivity by controlling and managing changes to requirements
