To gain confidence that installation procedures are accurate and workable enabling any defects to be addressed in readiness for implementation or roll out.
If you don’t do installability testing the Installation may fail and the procedures may not work. The system once installed may not be configured correctly.


On many programmes and large projects, testing will take up a significant portion of the budget. But it will receive less management attention than an activity of this size warrants.
