DESCRIPTION
In the January Mainframe Virtual User Group (VUG) meeting, guest speaker, Benny Westaedt, CEO and Chief Architect of PSW solutions discussed “How ChangeMan ZMF’s ERO option saves you resources and money.” Benny stepped our audience through the Enterprise Release Option (ERO) of ChangeMan ZMF and made a very compelling case for how ERO does save time and resources in a manner that was accessible to all technical levels and easily understood by those with or without actual ERO experience.TRANSCRIPT

Project Death Star
Where did it go wrong?
» First Release = Success
• Flagship of the Galactic Empire • Moon-Sized imperial military battlestation • Planet-destroying superlaser • Thousands of stationed troops

Those involved in “Project Death-Star” thought going to production with: • No Risk or Impact analysis, • A minimum amount of testing • And a thermal exhaust port from the central reactor core Was not going to be an issue. . . . .
However …
1/23/14 10
» … They were wrong!
1/23/14 11
»
Not only was there a total loss of Hardware, Software and Resources. . . .
The Result?
1/23/14 12
»
. . . . There was also some staff reduction.
1/23/14 13
» Death Star 2.0 lessons learned
• Load balanced central reactor core • No direct access to the central reactor core including
exhaust port • Do NOT underestimate the competition
. . . right?
1/23/14 14
» Project DS 2.0 Release Review These rebels are mad! They don’t have a chance of winning this time..
Yes sir.
Wait!. . .The issues with the central reactor core were resolved, right?
. . . . . Erm
It is too late to correct it now, Captain. . . I mean what are the odds it could happen again?

» Oops !!!

» Did you ever had to:
• Fix a release bug • Remove a package from a release • Removing components from a
release

Risk Management
• Testing • Dependency mngt
– Copybooks – Load relationships – Overlays
• Parallel development
• Audit – out of sync recompile
• Check points • Build process automation
(concatenation) • Development path

» We should have practiced ERO! . . . . .
• Release mngt • Change mngt • Incident mngt • Problem mngt • Impact analysis • Risk analysis • Test mngt • Dependency mngt
Where did the Empire go wrong? . . . . . . . TWICE!

» Summary
• Test and build environments cost precious resources: not planning for them costs even more.
• The right ERO implementation helps you balance your resources and makes sure you use the right ones at the right time.
• Disk space, CPU time, human resources, quality and risk can be managed by ERO. • The build management and impact analysis features, deliver crucial information about the
potential risk and quality impact.
