A Brief is created by a Brief Manager. Each Brief is associated with a particular team, an Access Group. Each User is a member of an (or more than one) Access Group.
The advantage of common access is that each member of the team who has Document Manager, Brief Manager or Document Filer access rights (including the client, if given Document Manager or Document Filer rights) shares the workload of creating a common centralised Brief. As documents are created or received they can be uploaded, viewed and downloaded.
Members of the team progressively can add documents to the Brief and follow its progress. Another advantage is that the documents will be filed and stored with an organised structure.
A client, expert or other person may also be permitted to view certain documents. The Viewer, Client or Expert category of User can be used for this purpose.
