Inventorying Computer Hardware
A systems analyst needs to inventory what computer hardware is already available in the organi-
zation. As will become apparent, some of the hardware options involve expanding or recycling
current hardware, so it is important to know what is on hand.
If an updated computer hardware inventory is unavailable, the systems analyst needs to set
one up quickly and carry through on it. It is important to know the following:

1. The type of equipment, including model number and manufacturer
2. The operation status of the equipment, such as on order, operating, in storage, or in need of
repair
3. The estimated age of the equipment
4. The projected life of the equipment
5. The physical location of the equipment
6. The department or person considered responsible for the equipment
7. The financial arrangement for the equipment, such as owned, leased, or rented
