AnswertoYourTurn1-1:BeinganAnalyst t t t t t t t




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


analyst, 2) business analyst, 3) requirements analyst, 4) infrastructure analyst, or 5)
t t t t t t t t t t t t


change management analyst. Verify that the student has correctly associated the skills
t t t t t t t t t t t t


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


to acquire those skills. The roles and the names used to describe them may vary from
t t t t t t t t t t t t t t t t


organization to organization.

AnswertoYourTurn1-2:ImplementingaSatelliteDataNetwork t t t t t t t t t




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
t t t t t t t t t t


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


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
t t t t t t t t t t t t t


support for the project. One solution would be to plan and provide for sufficient
t t t t t t t t t t t t t t


training that demonstrates how their jobs might be easier to accomplish with the
t t t t t t t t t t t t t


automated system.

Qantas provides for an ―ice-breaker‖ discussion topic for the first class. Perhaps group the

the importance of IT project success.

Efficiency gains are mentioned in this Concept in Action. What are the drawbacks to this
t t t t t t t t t t t t t t


scenario? Is it as easy as it seems? Issues such as Wi-Fi coverage on a farm, perhaps even
t t t t t t t t t t t t t t t t t t


cellular coverage can come into play as can weather, dust, and other issues inherent with a
t t t t t t t t t t t t t t t t


farming enterprise.

t t t t t t t t t t




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


associated with increasing the level of services to high-quality customers which would
t t t t t t t t t t t t


result in a 10% increase in customer satisfaction.

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.
