NOT tech “cool” driven.
– 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..
• How to best monitor each service.
• SLA with service providers
