Accelerating Product and Service Innovation | Rational

Software drives today’s innovation for a smarter planetTransforming the way we live, work, and play



Yet software quality is a major problem across all industries

Software is blamed for more majorbusiness problems than any other man-made product.

Poor software quality has become one ofthe most expensive topics in humanhistory– $150+ billion per year in U.S.

– $500+ billion per year worldwide.

Projects cancelled due to poor quality are15% more costly than successful projectsof the same size and type.

The future of testing: New IBM Rational solutions

IBM Rational Test Workbench–Enable functional, performance and integrationtesting throughout your project lifecycle.

–With a scriptless, wizard-driven test authoringenvironment and support for more than 70technologies and protocols,

IBM Rational Performance Test Server–Save time and effort by reusing your functionalintegration tests for performance testing

–Combine your tests to model real-world scenariosand assess the impact of load on your integratedinfrastructure.

IBM Rational Test Virtualization Server–Model real system behavior to eliminate testdependencies and simulate production,

–Accelerate testing and reduce the setup andinfrastructure costs of traditional testing environments.

Blockers for End to End testing

“The environmentwill be another 3

weeks”

“Too costly to setup a testmessage feed for test”

“We’re stillwaiting for them

to deploy”

“The dev team hasn’tstarted work on it yet”

Test Virtualization is an enabler forcontinuous Integration Testing

Services, applications, systems areintroduced into the continuous integrationcycle in a prioritized, controlled fashion.

IBM Rational Test Virtualization Solution has proven measureableresults and business value

Major telecom carrierMultiple test releases required additionaltest resources, increasing testing costs

Solution: Virtualized services and createdreusable test cases across multiple

environments Results: Reduced testing time by 50%,

saving $800K over 3 years

A leading global financial servicesfirm with assets of over $2 trillionMany disparate legacy format to be

migrated to next gen payments system Solution: Virtualized third-party systems

otherwise unavailable for testing Results: Reduced manual testing from 10 days

to 10 minutes, saving over $7 million to date

Major U.S. insurerRecognized manual efforts insufficient

for complex SOA and web services Solution: Agile middleware solution created

to match the legacy systems’ functionality Results: Reduced testing by 95% to 2 hours;

reduced ‘rate filing’ validation by 94%to 320 hours

Global manufacturer acquirescompetitor

Migrate off rented infrastructure ontocompany’s standardized middleware platform

Solution: Virtualized critical, unavailable systemsduring migration

Results: Fully integrated in 6 months – 2 monthsahead of schedule; saved significant rental costs

and dependencies on third-party systems
