I have 5 vendors working on a project. All five vendors have tasks which are significant projects in their onw right. There are interdenpendencies. I want to coordinate the project in a way that there is one gantt chart for the overall project which all vendors and their teams can see, their project managers can edit and communicate. I want to attach project related documents like drawings, qoutes, email exchange with supplier etc but want to be selective as to who can see what document; i don't want to share confidential documents with every body with access to project sheet but want to have all relevant documents attached/stored witht the projectd sheet.
Would appreciate your help.
