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?

» 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?

» 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.
