How often should the validation process be initiated in a review project?

Initiating the validation process whenever the validation queue has sufficient documents is considered the best practice in a review project. This approach ensures that the validation process is ongoing and responsive to the actual workload, allowing for timely corrections and adjustments as needed rather than postponing validation until a project is completed. Such continuous validation helps maintain the quality of the review work, ensures higher accuracy, and mitigates the risk of accumulating errors over time.

In contrast to validating only at the end of the project, which could lead to discovering significant issues too late in the process, or doing so on a rigid schedule like once a month, which may not align with the document flow, this method allows for more flexibility and adaptability. Similarly, validating daily may not be necessary if there aren't enough documents to warrant that frequency, thereby making option B the most effective and efficient strategy.
