# File review

Multiple document reviews, approval processes, external reviews, reports and signatures.


## Detailed description

BabelBird Enterprise Drive provides a powerful document review function, designed to help users efficiently manage the document approval and revision process. Document review is a collaborative work process that allows users to initiate a document review, invite reviewers to view the document, provide comments and suggestions, and ultimately determine whether the document requires modification or approval.

### Main features

- Multi-document review: Supports review of multiple documents at the same time. Users can initiate review of multiple documents at one time to ensure an efficient review and approval process.

- File Lock: Files will be automatically locked during the review process to prevent other users from editing or uploading new versions, ensuring that the file content will not be changed during the review process.

- File preview and comments: Reviewers can add comments and fill in review comments when previewing the file to provide detailed feedback. This helps to better understand the file content and provide targeted recommendations.

- Review process: Users can choose different review processes, including freely defining the review process, using a preset review process, or restricting the use of specific review processes. This allows different departments to choose the appropriate approval process based on their needs.

- Multi-stage approval: The approval process supports multiple stages, and one or more approvers can be set for each stage. Users can define a pass ratio, for example, if 50% of approvers pass, a certain stage can be passed.

- Invite external reviewers: Users can invite external members (via email or mobile phone number) to participate in document review to obtain more feedback from different perspectives, such as inviting external experts during thesis defense.

- Approval report: After each document review, an approval report will be generated to record the review opinions of participants at each stage for tracking and analysis of the approval results.

- Review signature: supports inserting a signature on the manuscript after the review is completed and downloading it as a PDF.

- My Review Column: Users can view and manage all stages of all review documents related to themselves in the "My Review" column, including initiated reviews and invited reviews.

### Technical architecture

The implementation of the document review function involves the following technologies and modules:

- Review process definition: Different review processes are defined in the background, including stage setting, approver selection, passing ratio setting, etc. These processes are available to front-end users for selection.

- Department-specific approval processes: Different departments can choose different approval processes and choose to freely define, preset or limit specific approval processes as needed.

- Multi-stage approval: Multi-stage approval can be achieved, and each stage has different approval requirements, including the selection of approvers and the passing ratio. You can also set whether a certain stage can be skipped.

- Invitation of external approvers: Supports inviting external members to participate in document review, and invites via email or mobile phone number.

- Approval reports: Generate approval reports to record review opinions at each stage for tracking and analysis of approval results.

### Advantages of document review

The document review function helps users efficiently manage the document approval and revision process to ensure the accuracy and compliance of document content. Users can use document reviews to ensure documents have been adequately reviewed and discussed to meet their work needs and compliance requirements. The introduction of this feature increases the depth of file collaboration and management, providing users with more powerful file collaboration tools.
