Rational Development and Test Environment for System z
Business constraints with mainframe development today
Which limits the amount of System z production workload coming online
“Operations tell me it will
take two months to get my
test system allocated.”
“I can only test my batch
applications in offline hours.
Online apps consume the 9-5 cycles.”
“It is difficult for my developers
to learn the mainframe.
Operations controls can prevent
experimentation by developers..”
“I want to try out creating Event
Processing and ATOM apps, but
my system isn’t scheduled for a
CICS update till 2013.”

“My development capacity chargeback is consuming my entire budget.
I can’t spend on tools.”
“We don’t have the capital
budget to obtain more mainframe
test resources for my developers. It’s
easier and cheaper to get a Windows or Unix
box.”
“I can’t even work on Mondays!
Production workload kicks me off.”
“The Mainframe isn’t cool anymore.
It’s faster and cheaper to develop
on a Unix platform.”

Benefits of Rational Development and Test Environment for System z
 Better quality
– Better development and test coverage earlier in the
cycle- defects eliminated at code phase cost 12x less
than those found in QA
– Enable easier problem determination with isolated
environments
 Free up development and test MIPS for higher
value workloads
– Reduce development and test costs, including
development and test capacity chargebacks
– Implement DevOps practices to improve quality and
delivery time without consuming mainframe resources
 Reduce cycle time
– Enable teams to work in parallel by distributing dev and
test activities
– Liberate developers to rapidly prototype application
changes- no waiting for operations
– Automate activities without worrying about MIPS
consumption
