needed with the type of analyst for which they aspire and that the student has created a plan

While answers may vary, answers might include the following:
t t t t t t t t
1. A cost-benefit analysis, along with other financial processes (ROI, etc.) would
t t t t t t t t t t
certainly reveal that a just-in-time (JIT) inventory can reduce inventory costs and
t t t t t t t t t t t t
increase revenue. A standard communication line, encrypted or not, would not be
t t t t t t t t t t t t
able to handle the high bandwidth needed for data, voice and video transmissions.
t t t t t t t t t t t t t
2. A competitor would be able to narrow the gap by adopting the JIT type of
t t t t t t t t t t t t t t
inventory management. Voice and video are not necessary to keep the inventory up
t t t t t t t t t t t t t
to date on a timely basis, data transmissions alone would work well.

1. Issues arising from digital signatures and electronic documents typically focus on
t t t t t t t t t t
establishing validity for signatures and originators. As these issues can be
t t t t t t t t t t t
overcome using certificates and encryption, they don‘t necessarily affect the

project feasibility. However, they do need to be addressed.

2. Answers will vary. The project champion, organizational management, and t t t t t t t t
perhaps most importantly a subset of the stakeholders must believe in and show

Carlson Hospitality can use the information from the survey to determine whether the
t t t t t t t t t t t t
one-point increase in market share revenue ($20 million per point) will offset costs
t t t t t t t t t t t t t

Answerto ConceptsinAction1-E: ReturnonInvestment t t t t t t t t
1. One method for determining a return on investment is to complete a Cost-Benefit
t t t t t t t t t t t t
Analysis using the Present Value Method. Many of the costs for server
t t t t t t t t t t t t
virtualization are associated with the initial construction: physical manipulation of
t t t t t t t t t t
the servers and software licensing. The ongoing costs of labor in updating and
t t t t t t t t t t t t t
accessing tables would be relatively small. Using this type of analysis would allow
t t t t t t t t t t t t t
the project sponsors to show how the benefits of the virtualization would be realized
t t t t t t t t t t t t t t
on a long term basis.t t t t t
2. Implementing a major change to a system should certainly include a systems t t t t t t t t t t t
analyst. Systems analysts typically have a broad view of the system, and would be
t t t t t t t t t t t t t t
able to ascertain how virtualizing the servers will affect the whole system.
