I guess I have to spell everything out for you. It finds the incompatibility *BEFORE* it's actually deployed into a live environment where Joe User finds out he can't open his internets anymore. Then you find out if you can *FIX* the incompatibility before it actually affects any of your users. Pretty cool huh?
So you are going to test multiple computers with different OS, with different Service Packs on them, with other various other software on it, before you send it out to all.
Because when you are dealing with a large amount of computers and workers it is rare that you will find that all of them have the same bios, motherboards, memory amounts, chip sets, operating systems, service pack or other updates, other software and any other thing that could potentially screw up a new software introduced to all of these computers.
Not to mention any computers where for whatever reason the user is stuck in an update loop where they can no longer do their critical updates because they will download but will not install and you can not get them to understand how to fix it over the phone so they either just let it be or turn off all automatic updates.
And again it does not take into account any users who have downloaded software they should not have and they wind up having active viruses or trojans on their computers. Or they have too many virus, adaware type prevention programs that screw up with some of the other software that causes issues.
Doing a test run on a computer and saying...hey it works so let's deploy it to all and then expecting it to be the same for every computer IN A LARGE NETWORK of computers is kind of naive at best.
And this does not even take into account the users on the other end with their cart load of IDTENT errors.
In a regular world, where everyone on the network has everything the same it will work. And that does work for many places because they are mostly smaller groups of computers and users.
But when you are dealing with a larger network...chances are you are going to find problems with it.
Heck even if you don't do things over the network, even if you have all the same computers and hardware and you just ghost one hard drive to another so everything is the same...you can still run into a computer or two wigging out for whatever reason even though everything, in theory, is the same...and that is not even doing it over a network.
