What function allows collaboration by tracking changes made by different users in Smartsheet?

The function that allows collaboration by tracking changes made by different users in Smartsheet is the version history. This feature captures and records all modifications made to a sheet, enabling users to view a complete history of changes over time. Users can see who made specific updates and when those changes were made, which is crucial for maintaining transparency and accountability in collaborative environments. Additionally, version history allows users to revert back to previous versions if necessary, enhancing the overall effectiveness of teamwork by ensuring that alterations can be tracked and managed efficiently.

While task assignments, activity logs, and the commenting feature facilitate collaboration, they do not specifically focus on tracking changes in the same comprehensive manner as version history. Task assignments help in delegating responsibilities, activity logs provide a high-level overview of user interactions, and the commenting feature supports discussions, but none of these options provide the detailed tracking necessary for understanding the full context of modifications to the data.
