The IT lifecycle begins at the start of the technology’s usage period. This time period lasts as long as the piece of technology continues to function properly.
The duration of the time period is dependent on a variety of variables, such as the type of technology being utilized and with what parameters it will be used.
An example of this would be a desktop setup at your organization. The expected lifespan for a desktop is five to eight years, but with proper maintenance and upgrades, this time period can be extended.
