How can you resolve a dispute regarding when a task was marked as complete?

To determine when a task was marked as complete in Smartsheet, examining the cell history is the most effective approach. The cell history feature provides a detailed log of every change made to a specific cell, including timestamps for when the task status was changed to complete. This allows users to see exactly when the change occurred, who made it, and can help clarify any discrepancies or disputes about the data.

While other options may provide some context or information related to the task, they do not offer the precise detail needed to resolve timing disputes. Task reports can summarize task progress but do not track specific edit history. Asking team members may yield opinions but lacks definitive proof. Reviewing email correspondence may highlight communication regarding the task but won’t provide exact timestamps associated with task changes. Thus, turning to the cell history is the most accurate method for resolving disputes on task completion timing.
