* Some choices earn partial credit. To stay within the budget and still make sure Devil's Canyon has what it needs to operate, some tough choices are needed. Your decisions led to a one year cost of $774,180, which was $24,401 over budget. Your three year costs amounted to $1,098,540, which was $95,599 under budget.

2. Feedback on the Choices for Devil’s Canyon

Phase I: Software Choices

In this setting, software as a service and cloud computing that rely on Internet connectivity for all operations are too risky, given the frequency of snowstorms and associated downtime, so COTS or open source software installed on premises is a better choice. COTS would be preferred over open source, partly because of the shortage of IT staff at Devil's Canyon, and their limited skill set. For individual productivity, the Microsoft suite is the best choice, and also less costly in the long run. Phase II: Hardware Choices

A data center is a requirement for COTS or open source software. Desktops are the best choice, given the higher cost of purchasing and maintaining laptops. An attractive solution for mobile access is to combine desktops with smartphones. Staff would not be able to carry their laptops around the resort, but they could use their smartphones to access the systems, even from the ski lifts. The smartphones with GPS capabilities will also add improvements to safety, especially for rescue teams and during blizzards. Phase III: Network and Telecom Choices

A mix of fiber and twisted pair is preferred over all fiber, especially because guests will not have the interface cards for a fiber connection. Even if the resort installs wireless access points, guests may prefer Ethernet cables because the connections are typically faster and more reliable. Coaxial cable adds little to the expense for startup because it would be installed along with the fiber and twisted pair. If it is not installed at this time, the costs for installation would be much higher. The cable installation provides the resort with more flexibility for delivering television signals. The resort needs reliable wifi, so hot spots are essential. Though the resort gets spotty signals from existing cell towers in the geographic vicinity, reliable and strong signals will be an enormous benefit, so cell towers are a justifiable expenditure. For voice calls, the hosted virtual PBX may not be reliable because of snowstorms and Internet outages. The higher costs of maximum bandwidth for the resort's main is a justifiable expense that could make a very positive impression on customers who want to watch movies or play games. Phase IV: Special Purpose Systems

The security system is essential, but the costly smart lift tickets and mobile phone app would best be added later to stay within the budget. They are both attractive, but their costs will probably come down in the future. The web cam system is a good choice, given its much lower cost and its potential for earning revenue. Final Budget The best choices would lead to a 1 year cost of $749,779, and a 3 year cost of $1,194,139, and stay just within Ed’s budget.

Discussion Questions

1. If Devil's Canyon Resort already had built a data center in the basement of its hotel, and had room for expansion, would that affect your choices?

2. What are the pros and cons for the order in which the enterprise architecture choices were made (software, hardware, networks and telecommunications, and special purpose systems)?

3. Which parts of Devil's Canyon architecture do you think will need the most frequent upgrades or replacements?

4. If you were helping to design the enterprise architecture for a small college with a classroom building, a dormitory, and an administration building, how would it differ? What additional components might be needed to support the college's mission?
