The IT asset lifecycle is the general asset lifecycle with two things added: a holder who changes often, and storage that has to be wiped before the device leaves. A laptop in a small organisation is bought, issued to a person, used for three or four years, returned when they leave, reissued to someone else or retired, and finally disposed of with its data destroyed. Each of those is a row on the IT inventory with a date, and the inventory that has all of them can answer the three questions IT gets asked: who has what, what is out of warranty, and where did the leaver's laptop go. This page sets out the stages and what the register records at each, for the IT manager or office manager of a company with five to two hundred people.
Purchase and receipt: the line is opened with serial, cost and warranty end
The device is ordered against a budget line and received with a serial number. The inventory opens a line with the model, the serial number, the cost, the purchase date, the warranty end date and the supplier. Cost matters for the fixed asset register, where laptops above the organisation's threshold are depreciated; warranty end matters for the inventory, where the out-of-warranty count is the figure the free IT asset inventory worksheet on this site turns into a replacement value and a monthly reserve.
Issue and use: the holder is named and the seats are counted against them
The device is issued to a named person with the date, and the paid seats they use are counted against them on the same record: the mail suite, the security agent, the design tool. Use is the long stage, and the register's job during it is to stay true through the small movements nobody reports: the spare laptop lent for a week, the phone swapped after a cracked screen. A discovery pass against the network, worked on the discovery coverage worksheet here, is how the register finds out what moved without being told.
Return, reissue and retirement: the leaver's laptop is the test
When a person leaves, the device is returned with the date, the data is wiped and the wipe is recorded, and the seats are released so they are not paid for another year. The device is then reissued, which is a new issue row, or retired, which moves it to the disposal stage. Organisations that fail this step do so silently: the leaver's seat renews, the laptop sits in a drawer as an asset that is still on the books, and the register shows a holder who left in March.
Disposal: the line closes with a date, the proceeds and the sanitisation record
A device with storage is disposed of in two records: the register line closes with the date and any proceeds, and the disposal carries the record that the storage was sanitised in the way NIST SP 800-88 describes, whether by wiping, by destruction or by the recycler's certificate. The line is kept as closed, not deleted; the year-end fixed asset report and any later question about where a serial number went both need it.
Questions people ask about it asset lifecycle
How long is the IT asset lifecycle for a laptop?
Whatever the organisation's refresh cycle says, commonly three to five years. The register does not decide the life; it records the life the organisation chose and runs the depreciation over it.
What is the difference between the IT asset lifecycle and IT asset management?
The lifecycle is the sequence of stages a device passes through. IT asset management is the practice of keeping the register through those stages. One is what happens; the other is the record of it.
Does a phone need a lifecycle record as well?
Yes, and it changes hands more often than a laptop. A phone that is issued, swapped, returned and reissued without rows on the register is the device most likely to be missing at the annual count.
What has to be recorded when a device is disposed of?
The date, the proceeds if any, the holder it was returned from, and the record that its storage was sanitised. Without the last one, the organisation cannot show what happened to the data on it.
