I'm looking for the same thing. In my search for KPI's around GIS specifics and the clients / business operations it supports I haven't found much in terms of direct GIS related KPI's. I have found information on how to use GIS to demonstrate KPI's for other things such as asset management for example which isn't what I'm after.
To give some context to individuals in the organization around GIS and to demonstrate the effectiveness of GIS to the organization KPI's would be valuable in doing so.
I would appreciate any suggestions.
thx.
