Requirements management, requirements definition and requirements engineering practices are the cornerstones of project success.
In a recent industry study, organisations surveyed incurred a cost of as much as 60% on time and budget when they used poor requirements practices. Organisations 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.
Rational software offers best practices in requirements definition and requirements management, proven to save time and money by helping you:
- Reduce rework and accelerate time to market by collaborating with your stakeholders
- Increase productivity by controlling and managing changes to requirements
- Minimise cost and risk by measuring the impact of changes as they occur
- Demonstrate compliance by ensuring full traceability of requirements
