I will see what I can do. I am between projects right now so I have some time. I think I will go back and revisit that spreadsheet and add some new roles based on my expereinces over since 2009.
Potential Roles
Windchill System Admin
Windchill DBA - useually a general DBA but with some Windchill duties
Windchill Business Admin
CAD Admin
EDA Admin
Integration Admin
Manager
Director
Bussiness Power User
Any role you think may be missing off this list please feel free to add. This is for a sustaining organization, I think it will be to hard to define roles and hours for the various project work/other work spikes that may come into play
