To confirm a workflow's execution, what is essential?

To confirm a workflow's execution, saving the delivery and workflow is essential because it ensures that all the configuration, settings, and data related to the workflow are captured and stored correctly within the system. Saving the workflow will preserve its state at the moment of execution, allowing for retrieval and analysis later if needed. This step is vital to ensure that any changes made during workflow design and execution are not lost and can be referenced in the future, which is crucial for tracking and auditing purposes.

The other options, while practical in certain contexts, do not directly contribute to the confirmation of a workflow's execution in the same way that saving does. For instance, prior approval from all reviewers might be part of a governance process but does not verify that the workflow has been executed. Final summary report generation could provide insights into the execution but is an outcome rather than a confirmation of the process itself. The completion of all activities is also important; however, without saving the workflow, there is no guarantee that the completed state is documented. Therefore, saving the delivery and workflow stands out as the most direct and critical way to confirm execution.
