The management model pm3 was developed in sweden back in the late 90’ies.
Today many companies and organisations in sweden has adopted this model.
Right now I have two different categories of areas that I maintaine thru pm3.
First of are all accounting systems, HR and BI together with some smaller service systems (booking, visiting administration and so on).
The second is even less homogeneous with systems like administration of foundations, watchdogs and spread the ashes of dead people (!)
