Creating requirement document snapshots
A snapshot is a version of a requirement document captured at a specific point in time. Snapshots are used for comparing document versions and viewing differences between them.
Snapshots are typically created in conjunction with project milestones. For example, you may create a snapshot when the first draft of a document is complete. If you need to refer to the original document version later, you can view the differences between the snapshot and a newer version to see what changed.
When you create a snapshot, current versions of all requirements included in the document are saved in the snapshot. If a requirement in a snapshot changes, the old requirement is versioned and archived. See Viewing historical requirement versions.
After you create a snapshot, you can compare it to the current document version or another snapshot to view the differences. See Viewing all changes between requirement document snapshots.
Tip: Snapshots and baselines have some similarities, but many differences. Review information about the differences before choosing which one to use.
1. Select a document in the Requirement Documents list. You can also select the document in the requirements tree when you are viewing a document.
