3.2.4 Milestone Events
Within each migration, certain activities should be identified as key activities, the
attainment of which can signal significant progress (or the lack of attainment, a
schedule slippage). These activities are typically called milestone events or just
milestones. Each customer should identify the milestones most important in their
migration.
The following are some suggested VSE to OS/390 migration milestones:
Migration Plan completed, reviewed, and approved.
VSE software inventory completed.
All vendor support committed.
Essential education completed.
Necessary hardware installed.
Installation of OS/390 and related products completed.
Initial OS/390 IPL performed.
Pilot conversion completed.
Each major application′s successful conversion.
Stress/Production tests completed.
Operator education and Run Books completed.
Production criteria attained.
Production implementation initiated.
Once milestones are defined, periodic ″checkpoints″ can be scheduled to
monitor successful milestone completion; that is, project progress.
