Rational Team Concert was implemented at UniCredit Leasing Austria to modernize their development environment and applications. The old development process relied on custom scripts and faced issues with support and new operating system versions. RTC provided a fully automated process with version control and application lifecycle management using Eclipse. It solved issues around OS dependencies and simplified their software development process. While transition took planning and infrastructure knowledge, the "1:1" migration approach helped teams transition smoothly to the new platform.

4. THE HISTORY
WHERE CUSTOMER CAME FROM …
 COBOL as the development language (some PL/I)
Approximately 12.000 program source files
Native 5250 environment for development (PDM)
 i5/OS V5R2 as the base OS for the main development machine
 ADM/400 (Software Delivery/Application Lifecycle Management)
Highly customized with hardwired connections into a custom built ticket solution
Build process relying on custom written scripts and utilities
OUT OF SUPPORT AND NO SUPPORT FOR NEW OS VERSIONS
 Lotus Notes for Ticket/Incident/Problem Management
 Staged Environment(Development/Test/Production)
 Management of development agendas, planning and controlling of the
performance only possible with extensive manual effort

28. NEW WAY OF THINKING
 ALL SOURCES ARE ONLY STORED IN RTC
 All Changes must have a Ticket number
 Developer has no longer direct access to Test/Integration/Production
 Developer has a personal Sandbox out of RTC
 Fully automated
www.cwi.at 28

29. PAINS THEY SOLVED
 OS Version Dependency
Native OS support
Supports actual OS versions
Future-proof
 Software Development Process
Eclipse-based (open standard)
GUI utilizing modern IDE paradigms with integrated outlines, debugging, watch, …
Web based client for management and contribution available
Usage can be expanded to other languages/platforms as needed
On-boarding of new team members easier
No Single Point of Failure anymore (fully automated process)
www.cwi.at 29

30. LESSONS LEARNED DURING
TRANSITION
 Have a Champion within the development team
 “1:1”-Migration of the existing approach helped teams to move to new
platform
 Infrastructure knowledge needed (System i and IBM WebSphere
Application Server)
 Because of good planning transition was rather smooth 
 Don´t forget the people!
www.cwi.at 30

31. CONCLUSION
 „The genius of a construction lies in its simplicity. Everybody can build
complicated things”
(Sergei P. Korolev)
 “A Rule is a good Rule when it makes you faster”
Reassess old paradigms and architecture
 Devide and rule
Phase model makes it easier to break the transition into small and better controllable
pieces
“We at UniCredit Leasing Austria have opted for the combined toolset of
Rational Team Concert for IBM i and Rational Developer
for IBM i because they provide us with the best support for modern
approaches to software engineering for the
IBM i platform.”
