What about the lab?
But the truth is...
But we know the challenges:
• Who will setup the lab?
• How long will it take? What type of paperwork/processes?
• Do you have the infrastructure?
• What if you want to set it up on the Public/Private Cloud with various vendors?

What about the application build?
And to take it further…
We know the challenges:
• Do you know when the build will be ready?
• Is it set up correctly?
• Is the process repeatable?
• What happens to the lab after testing is done?

Improve Application Deployment Quality
• Reduce people and process errors
through automation
• Ensure consistency of deployment
• Leverage knowledge across stages
• Increase test coverage with additional
testing
Achieve application deployment success rates as high as 95%*
“Went from 20%-30% failure rates to
0.15% failure rates for application
release processes under automation”
“Prior to automation, applications
would be deployed slightly differently
across each server. With automation,
there is consistency and control”
