– Money flows with service support philosophy not with trophy building.

– Service Identification • What’s on your network?• How critical is it?

– fire alarms, security, ID systems, HVAC, temperature alarms on refrigerators, Medical systems, student systems, payroll, research projects, Voice, etc..
