There could be hundreds or thousands of components to change, migrate, upgrade, affect somehow in an Infrastructure Project.
There might be a very finite list of things to apply to each set of the Infrastructure and these changes will have to be applied in the same manner for each component.
Once you set up a process for applying these changes OR migrating servers, data bases, web apps, etc., this process will need to be repeated with Quality, Precision, Dependency and BOREDOM for each of the components that will be affected.
It would be much more important to manage the BOREDOM than the other aspects once your team gets started making these changes. Of course, in some cases, you COULD acquire propagation software that would execute a script to make your changes over and over again and, therefore, reduce the BOREDOM.
But, what else could we as Project Managers do to increase the likelihood of consistent, reliable results?
