Service Delivery Areas

The Infrastructure Services division provides support in five major areas that are described below:

  1. The central Service Desk is the single point of contact to make it easier for customers to report incidents and requests related to technology. The central Service Desk reduces operational costs and improves usage of available ITSD resources. The technicians coordinate and resolve reported incidents as quickly as possible over the telephone and through e-mail or remote desktop assistance. The Service Desk also provides assistance for other activities such as user account passwords and change requests. The technicians create a tracking ticket based on the type of service required and assign the ticket to the next level of support if they are unable to resolve the issue.
  1. Desktop technicians are the first point of escalation if the Service Desk technicians cannot resolve the incident. The desktop technicians provide guidance and instruction to the Service Desk technicians to diagnose and resolve incidents as well as provide support based on tickets escalated by the Service Desk. The desktop technicians are also responsible for completing special projects such as major upgrades to operating system and desktop applications. The desktop technicians typically contact the customer to schedule an appointment for an on-site visit or provide support using remote desktop assistance.
  1. Network Services includes all services to provide and maintain the County’s network infrastructure, which is based on Ethernet and consists of two core switches connected via a 1 Gbps wide area network (WAN) fiber link.
