Cerebro offers a tool to collect User Statistics - across all projects in the universe. Go to Main menu/Tools/Users&Resources Ststistics… to launch it.
There is a switch in the upper side of the User Ststistics window that toggles between the two modes:
My statistics – the data analyzed and displayed relates to the current user only;
Users/Resources statistics – offers a list of users and resources to pick one or more entities for analysis from.
Parameters such as time frames or user’s tasks nesting levels are adjustable.
Results which include statistics on the work done by users and calculation of their wages are displayed in the table, which can be exported as a spreadsheet or copied to clipboard.
