According to Veeva, the Collaborative Authoring feature in Veeva Vault ‘performs better with smaller files (less than 100 pages) and small teams (5-10 authors)’. They state that ‘PleaseReview may be a better solution if you are collaborating with large groups of reviewers and looking to maintain a very high level of control over the document and the review process.’  

PleaseReview is better suited to complex and structured document reviews. It supports simultaneous collaboration on larger documents, across multiple file formats, with high-volume teams (~10 – 400+ reviewers working in real-time). It also enables easy and secure collaboration with external reviewers. The document owner has unparalleled control, visibility and reporting of all document activity.

Yes! It is very easy to invite external parties, who do not have Vault licences, to collaborate on a document review in PleaseReview from. While the document owner drives the review from within Vault, the external collaborator reviews the document in the native version of PleaseReview. 

External collaboration is highly secure in PleaseReview. You can control what the user can access, even down to specific paragraphs of text. So, you can rest assured that your sensitive data is secure.
