Which document is NOT an input for the disposal process?

The maintenance strategy is not typically considered an input for the disposal process. The disposal process focuses on how to retire a system at the end of its life cycle, ensuring that it is done in a safe, environmentally responsible, and cost-effective way. Inputs for this process usually include documents that provide guidelines or constraints relevant to the actual disposal or repurposing of the system, such as the validated system, which reflects the final configuration, the concept document that outlines the intended lifespan and requirements, and any disposal constraints impacting design choices.

A maintenance strategy primarily addresses the ongoing upkeep and operational phase of a system and does not outline how the system should be disposed of. While maintenance may indirectly impact decisions made during disposal, it does not serve as a foundational document for the disposal process itself. This is why it is not included as an input for that phase.
