Need for Requirements Management
•
Reliance on the intelligent informed individual (People over Process)
•
•
Staff Turnover and long projects
Many requirements from multiple stakeholders that staff are expected
to know
•
Contract, Laws, regulations, interfacing facilities, etc.
• Easily exceed 10,000
•
Requirements are not implemented in design
•
•
They do not systematically flow down to design or to suppliers.
Requirements changes are not well understood prior to approval
•
Leads to unanticipated schedule delays and unexpected cost growth.
•
Requirements are incomplete, unclear and subject to widely varying
interpretations.
•
Unable to justify requirements readily
•
Difficulty verifying requirements were met.
2
Important Considerations for
Establishing a Program
•
Learn from Industry
•
•
Recognize that RM is an enterprise process
•
•
not just bookkeeping
Must be intertwined with system development
processes
•
•
ISO 29148, ISO 15288, etc.
Key Systems Engineering concepts are needed
Clear roles, responsibilities accountabilities &
authorities
• Process over tools
