Fig. Lifecycle model to indicate the stage at which functional obsolescence ("yellow") is most prevalent. Functional obsolescence is perhaps one of the most systemic forms of obsolescence that can affect groups of assets.
Fig. Retrofit of a conventional fire alarm control panel (FACP) to an addressable system is one example of an adaptive renewal to address technological obsolescence. It forms part of a larger strategy of obsolescence management.
