There are various features in MS CRM that allow for standardization, organization and long term efficiency. One of those features is the resource group. When you are putting together resource groups it is helpful to use the "Search" feature to subset your long list of available equiptment. If you are doing a million different things you might want to tag your equipment for easy searching.
For instance you might have resource group to put on a seminar. In this group you would have:
Equiptment: Projector, Flip chart, marketers, extension cord, surge protector etc.
People: The presenter and support personnel from the office
Facility: The location where you will hold the seminar.
If you define your items above with a key word it makes it easier to "search".
