A Sales person in IT industry, a planner in ad agency, a consultant for government, etc., etc.... Those proposal writers would tend to be a 'lone wolf'. That means their writings could be hardly accumulated as 'know-how' and would have less reusability.
Even if a rule to 'backup in the file server' is given, it will not lead to Centralized management just because of a reason: 'CUMBERSOME'. Most of these proposal files profoundly slumber in some folder on someone's personal computer. These files should have been shared with everybody.
The following Workflow is defined an activity of 'reading somebody else's Proposal', as a 'Task'.
In this sample, the writer registers Presentation materials which he/she think to him/herself that 'I did a good job'. Then two of the coworkers who are designated will read it. And at the same time, the file is backed up to the specified folder in Google Apps, the online storage on Cloud. (e.g. "Proposal for New customers", "Proposal for Existing customers", "Template/ Others")
