Support Structure

WP7 Software need a lightweight support structure

NetworkCost suite is the only “external” module of WP7

NetworkCost results are computed from a central MySQL Database

Iteam Representative is the entry point (bugzilla) 2 additional trained engineers to cover overloads and holidays
