3. The ROI of better Requirements Management
$500,000
69% net reduction in the cost of quality
$450,000 Return on investment within 6 months
$400,000 >75% improvement in productivity
$350,000
Rework
Testing
$300,000
$250,000 “In 6 months since deployment we’ve seen a 69%
net reduction in the cost of test preparation, testing,
$200,000
and rework by using IBM Rational DOORS and an
$150,000 improved requirements management process.
$100,000 Our team is testing and reworking comparable
functionality in one sixth the calendar time and
$50,000
one third the person hours. And we are able to

4. Reason #1 - Collaboration
• Screenplay/script like
requirements
• Script / requirements needed to
determine impact of any changes
• Script / requirements form the hub
for co-ordinating successful
teamwork

“I need to be able to manage the the same process and creating
relationship between customer the same metrics and reports”

Engineers
“I need access to a
live central
repository and to
know that I am
looking at the latest

requirements”

“I need a process
that ensures
traceability between

“I need to implement a process that enforces
and changes. I

7. But I’m comfortable with docs and
spreadsheets, wont this be a difficult
transition?
• Familiar hierarchical structure of a document and rich text editing
• Columns like a spreadsheet for additional properties
• Management of individual requirements for tracking and reuse

8. In-Context Collaboration
 Collaboration through
information discussions or
by formal review
 Email notification available
for review updates
 Dashboard widgets to show
review participation and
status

MBDA Missile Systems Link to Case Study
Increased customer satisfaction and provided a critical differentiator in a highly
competitive market
The need:
MBDA’s design teams were widely dispersed, with the challenge to share and
unify the specific knowledge of local individual engineers and designers.
Communication and traceability across the company's engineering organizations
were complex. They needed to improve and standardize its approach for defining,
communicating and analyzing the design for each missile system.
“MBDA has the ability to define

The benefits: MBDA Missile Systems
 Reduced typical system design time, speeding time to market, increasing
customer satisfaction and providing a critical differentiator in a highly
competitive market.
Solution components:
 Speeds identification of design incompatibilities, helping to avoid critical • IBM® Rational® DOORS®

10. Reason #2 – Traceability
• Breadcrumb trail = weak
traceability
• Product & systems development
needs stronger traceability
• Need easy way to create manage
and traceability
• Traceability helps with
conformance to customer
requirements and compliance to
regulations

18. Summary
• Agility without control = chaos!
– Requirements need to persist
beyond an iteration
– Requirements and supporting
information add more granularity to
user stories and epics
– Link requirements and task
management for traceability

19. Summary
• Agility without control = chaos!
• Traceability provides rationale
and context
– Retrace to key design decisions and
customer requirements
– RM tool makes traceability a benefit
not an overhead

20. Summary
• Agility without control = chaos!
• Traceability provides rationale and
context
• Effective collaboration is essential
– Must have access to the right version
