Refer to ICT components that can no longer perform their intended function due to loss of compatibility with other ICT systems or failing to meet standards. Obsolete components cannot and should not be used UNDP ICT environments. For example, hardware becomes obsolete when it is unable to efficiently run a minimal version of UNDP standard software. Software becomes obsolete when it is unable to integrate with other ICT infrastructure components or it is no longer able to run on hardware with minimum supported configuration defined in this document.
