Which action is not part of defining the workflow in an Active Learning project?

In an Active Learning project, defining the workflow involves establishing the processes and steps that will guide the classification and review of documents. Designating review groups, setting project access controls, and starting the classified document review are all essential elements in outlining how the project will be structured to ensure efficiency and accuracy.

Designating review groups is important because it allocates responsibilities among team members, ensuring that everyone knows their role in the review process. Setting project access controls provides security and limits document access to authorized personnel, which is crucial for maintaining the confidentiality of sensitive information. Starting the classified document review is a core part of the workflow, as it signifies the initiation of the process where actual document analysis and categorization begins.

Tagging hot documents, while a critical task in the review process, does not fall under the initial defining of the workflow. It occurs after the workflow is in place, as it involves the evaluation of documents to identify those that are particularly relevant or urgent based on the established criteria. Thus, it is an operational step rather than a foundational action in defining how the project will be executed.
