18. Challenges
• Long development and
testing duration
• Unavailability of
Dependent Services
• Frequent changes in the
WSDLs and test
environment
• Setting up new
environments
Benefits
 Enabled Parallel development
 Improved same sprint test coverage with continuous testing
 Stabilized environments for the consumer applications
 Isolated the dev / testing teams from frequent WSDL , environment changes
 Removed data dependencies across systems
 Reduced test data set up effort by 75%
 Removed all downstream issue analysis activities
$ Savings
 Cost of missing sprint target
 Cost of environment downtime
 Cost of data setup
 Overall cost of sequential
development to release timeline

DELIVERY TEAM “FORGETS” TO TURN OFF
VIRTUAL SERVICES

•HARDWARE / SOFTWARE COST
AVOIDANCE
$80 million spent on building/maintaining lower environments per year
•REMOVE WAIT TIMES

WHAT’S NEW FOR SERVICE VIRTUALIZATION AT
NORDSTROM?
VENDOR INTEGRATION
ENVIRONMENT
PRODUCTION TESTING DEVELOPER SANDBOX
Provide access to external partners
for internal non-production
Nordstrom resources (services,
APIs, etc.)
Performance testing in production with
Service Virtualization
Our website developers will soon
have a developer image that
includes all virtual models for all
interfaces
Remove security risks by
eliminating the need to access real
Nordstrom resources
Customer data and credit data remains
secure
Increase the testing coverage of unit
testing
Provide external partners with
compliant data for testing; pairing
service virtualization with test data
management tools
Holiday volume tests run in production
environment without risk
Early integration testing uncovers
defects long before they are
introduced down the delivery pipeline
