Answer to YourTurn 1-1: Being anAnalyst po po po po po po p
o




Student answers will vary, depending on their preferences regarding being a: 1)
po po po po po po po po po po po


systems analyst, 2) business analyst, 3) requirements analyst, 4) infrastructure
po po po po po po po po po po


analyst, or 5) change management analyst. Verify that the student has correctly
po po po po po po po po po po po po


associated the skills needed with the type of analyst for which they aspire and that
po po po po po po po po po po po po po po po


the student has created a plan to acquire those skills. The roles and the names
po po po po po po po po po po po po po po po


used to describe them may vary from organization to organization.

While answers may vary, answers might include the following:
po po po po po po po po


1. A cost-benefit analysis, along with other financial processes (ROI, etc.)
po po po po po po po po po


would certainly reveal that a just-in-time (JIT) inventory can reduce
po po po po po po po po po po


inventory costs and increase revenue. A standard communication line,
po po po po po po po po po


encrypted or not, would not be able to handle the high bandwidth needed for
po po po po po po po po po po po po po po


data, voice and video transmissions.
po po po po po


2. A competitor would be able to narrow the gap by adopting the JIT type of
po po po po po po po po po po po po po po


inventory management. Voice and video are not necessary to keep the
po po po po po po po po po po po


inventory up to date on a timely basis, data transmissions alone would
po po po po po po po po po po po po


work well.

1. Issues arising from digital signatures and electronic documents typically focus
po po po po po po po po po


on establishing validity for signatures and originators. As these issues can
po po po po po po po po po po po


be overcome using certificates and encryption, they don‘t necessarily affect
po po po po po po po po po po


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


2. Answers will vary. The project champion, organizational management, and
po po po po po po po po


perhaps most importantly a subset of the stakeholders must believe in and
po po po po po po po po po po po po


show support for the project. One solution would be to plan and provide
po po po po po po po po po po po po po


for sufficient training that demonstrates how their jobs might be easier to
po po po po po po po po po po po po


accomplish with the automated system.

Answer to Concepts inAction 1-D: Intangible Value at Carlson Hospitality
po po po p
o po po po po po po




Carlson Hospitality can use the information from the survey to determine
po po po po po po po po po po


whether the one-point increase in market share revenue ($20 million per point)
po po po po po po po po po po po po


will offset costs associated with increasing the level of services to high-quality
po po po po po po po po po po po po


customers which would result in a 10% increase in customer satisfaction.

Answer to Concepts inAction 1-E: Return on Investment
po po po po po po po po




1. One method for determining a return on investment is to complete a Cost-
po po po po po po po po po po po po


Benefit Analysis using the Present Value Method. Many of the costs for
po po po po po po po po po po po


server virtualization are associated with the initial construction: physical
po po po po po po po po po


manipulation of the servers and software licensing. The ongoing costs of
po po po po po po po po po po po


labor in updating and accessing tables would be relatively small. Using this
po po po po po po po po po po po po


type of analysis would allow the project sponsors to show how the benefits
po po po po po po po po po po po po po


of the virtualization would be realized on a long term basis.
po po po po po po po po po po po


2. Implementing a major change to a system should certainly include a systems po po po po po po po po po po po


analyst. Systems analysts typically have a broad view of the system, and
po po po po po po po po po po po po


would be able to ascertain how virtualizing the servers will affect the whole
po po po po po po po po po po po po po


system. po
