Question

1. Given that Valley Enterprises opted to implement Voice over Internet Protocol (VoIP) service
in its Phoenix, Arizona, service area. The company has 15 locations in the Phoenix area, all
with local area networks and all with secure Wi-Fi connections. The company’s current phone
system was designed and implemented in the 1950s, when Valley operated in three locations.
As more locations were added, standard telecommunications solutions were implemented,
with little thought devoted to compatibility. Over the years, phone services were added as
new buildings and facilities arose. Valley CEO Doug Wilson heard of VoIP at a trade show
and contacted TMR Telecommunications Consultants, requesting a bid. TMR spent a week
with the CIO of Valley Enterprises, gathering data, and submitted a bid for $50,000 in late
2007. The project was to be started by March 2008 and completed by January 2009. The bid
was accepted.
TMR started the project in March 2008. In late July 2008, TMR was bought out by Advanced
Communications of Scottsdale, Arizona. The merger delayed the project by over a month
initially. In early September 2008, some of the same personnel from TMR, as well as a new
project manager from Advanced Communications, went back to the project.
By March 2009, the project had already cost $150,000 and only 8 of the locations had
implemented VoIP. Advanced Communications insisted that the local area networks were
obsolete and were unable to carry the expanded load without major upgrades to the
bandwidth, the routers, and other telecommunications equipment.
(a) Is it time to end this project? Why or why not?
