Mission-critical systems require 24x7 maintenance support to ensure uninterrupted operations. Establishing a clear MOA or service contract with the responsible maintenance organization or vendor, as well as inventory control for critical items, is essential to maintaining continuous operations.

Implementation Guidance

1. Ensure that maintenance support for key IT assets shall be available to respond 24 X 7 immediately upon failure by implementing a service agreement stipulating such availability. 2. Verify that the maintenance support service agreement specifies 24 X 7 availability of maintenance support.
