of five primary types of obsolescence
and a force of
The process whereby an asset or the components of an asset become irreplacable due to changes in technology over time (ie. technological life).
Just imagine trying to repair your old tape deck or VCR - it is all about what parts are still available today and skills to work on old systems and technologies.
Listed below are the attributes of technological obsolescence as one of the replacement drivers of certain types of asset:
This form of obsolescence is the result of advancing technological developments by the manufacturers of the products and equipment. It may also be a result of planned obsolescence.
1. Fire Alarm Panel
Functional failure (F) occurs when replacement parts cannot be procured in a reasonable amount of time. For example, the parts for a fire alarm panel should be replaceable with hours or days (at the most) so that a protracted fire watch does not place the building and occupants at undue risk.
If a fire panel is damaged beyond repair by a water leak from adjacent pipes, then the panel is replaced for reasons of physical deterioration and not technological obsolescence.
Asset Management Principles
The effects of technological obsolescence can sometimes be managed and mitigated through the following:
Knowledge of the emerging difficulties in procuring replacement parts (“P”) for certain assets (such as fire alarm panels and elevator controls) helps owners understand the justification for modernization projects (“F”) and to plan accordingly.
