After creating a contract for IT contractors, the human resources department changed several clauses. The contract has gone through three revisions. Which of the following processes should the human resources department follow to track revisions?

Version validation refers to the process of verifying that a version of a document meets specific requirements or standards. While important in some contexts, it does not encompass the tracking of revisions or changes made to a document. Thus, it lacks the comprehensive tracking capabilities needed for managing multiple revisions effectively.

Version changes simply describe alterations made to a document but do not provide a structured method for tracking those changes. This term lacks the formalized process necessary to manage and document revisions efficiently, making it inadequate for the human resources department's needs in tracking contract modifications.

Version updates imply making improvements or modifications to a document, but like version changes, this term does not convey the systematic tracking of all revisions. It does not encompass the historical context or management features that version control provides, which are crucial for maintaining clarity in the documentation process.
