Roles (II)Physical
View
Real support organizations
often play multiple roles
Lines represent communication paths and, in our model, agreements.
We have not progressed very far with agreements yet.
Gray shading indicates that OSG Operations composed of effort from all the support centers.

Roles (III)Physical
ViewHave recognized need for general open support, but no one is contracted to provide it, so a “best effort” community support activity has started and is still taking shape.See Fred Luehring & Burt Holzman.
