NETW 563 You Decide Richton Toys Week 5 Keller

Scenario Summary

Richton Toys is an independent toy designer and has been around for about 2 years. Up until now, they have occupied 1/2 of a floor in a 30-story office tower, and are currently using a CAT5 Ethernet LAN that a previous tenant installed for their network. Recently, several users have installed a 802.11b network on their own. Moore H. Pschorr, the company CEO, is becoming concerned about the network setup, as corporate espionage is rampant in the toy industry, but so far, the WLAN is popular with his teams. Additionally, the sales department has been complaining about how unprofessional it is to have problems with or lose a connection during a sales meeting or conference. At this point in time, Richton Toys does not have a formal I.T. department, though Jim Coombes, a very tech-savvy user is currently managing it on the side. He also has some ideas for improving the network but may not have all of the skills to make the best decisions. Since the Human Resources department has a clearer view of the company’s future growth in the near future, CEO Moore has asked them to bring in your consulting firm to listen to some ideas from the team, and to provide them with some solid direction where to go….

Preview:

The first step that should be taken in the development of a strategy to respond to Richton Toy Company’s situation is to assess their networking needs and to evaluate the various options available for…
