Guest Access Efficiencies
This category describes the IT and business benefits of using “Lobby Ambassador” services. Prior
to migration to Cisco Unified Wireless Network, the IT staff were responsible for setting up and
eliminating guest access for visitors. We assume that the organization receives 360 visitors
annually and prior to the migration, IT spent 30 minutes per visitor to log, set up, and eliminate
guest access. With an average fully loaded hourly salary of $48, we calculated a savings after the
migration of $8,640 annually (360*0.50*$48). Table 13 illustrates this calculation.

This category illustrates business benefits for visitors including lawyers, auditors, consultants, and
contractors who bill the organization for the hours of service provided. Prior to migration, these
individuals would spend an hour waiting to receive guest access. With an average hourly rate of
$150, we calculate the productivity gain of $27,000 (360*0.5*$150). Table 14 presents the
calculation.
