Answer to Your Turn 1-1: Being an Analyst
Student answers will vary, depending on their preferences regarding
being a: 1) systems analyst, 2) business analyst, 3) requirements
analyst, 4) infrastructure analyst, or 5) change management analyst.
Verify that the student has correctly associated the skills needed
with the type of analyst for which they aspire and that the student
has created a plan to acquire those skills. The roles and the names
used to describe them may vary from organization to organization.
Answer to Your Turn 1-2: Implementing a Satellite Data Network
While answers may vary, answers might include the following:
1. A cost-benefit analysis, along with other financial processes
(ROI, etc.) would certainly reveal that a just-in-time (JIT)
inventory can reduce inventory costs and increase revenue. A
standard communication line, encrypted or not, would not be
able to handle the high bandwidth needed for data, voice and
video transmissions.
2. A competitor would be able to narrow the gap by adopting
the JIT type of inventory management. Voice and video are
not necessary to keep the inventory up to date on a timely
basis, data transmissions alone would work well.

Answer to Your Turn 1-3: Too Much Paper, Part 1
System Request
Element Description
Sponsor Document Manager.
Business Need Increase efficiency in storing, updating, and
retrieving information on employee injury
claims.
Business Automated system which allows for
Requirements electronic submission of reports via a
secure web site.
Business Value Reduce response time for employee
inquiries, increase effectiveness of storing,
updating, and retrieving employee injury
claims. Reduce storage costs of paper
files.
Special Issues Must have someone who understands how
to create and maintain a secure web site.
Must have resources to migrate paper files
to data storage. Must work within
HIPAA guidelines to ensure that medical
documents are treated according to
regulations.
Answer to Your Turn 1-4: Too Much Paper, Part 2
1. Issues arising from digital signatures and electronic documents
typically focus on establishing validity for signatures and
originators. As these issues can be 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 perhaps most importantly a subset of the
stakeholders must believe in and show support for the project.
One solution would be to plan and provide for sufficient
training that demonstrates how their jobs might be easier to
accomplish with the automated system.

Qantas provides for an ―ice-breaker‖ discussion topic for the first
class. Perhaps group the students and have them discuss this
company and then provide for class discussion about the
importance of IT project success.
Answer to Concepts in Action 1-B: BPI on the Farm
Efficiency gains are mentioned in this Concept in Action. What are
the drawbacks to this scenario? Is it as easy as it seems? Issues such
as Wi-Fi coverage on a farm, perhaps even cellular coverage can
come into play as can weather, dust, and other issues inherent with
a farming enterprise.

Answer to Concepts inAction 1-C: Interview with Don Hallacy, President,
Technology Services, Sprint Corporation
This is an opportune time to identify the responsibilities of the
differing roles that an analyst serves.
Answer to Concepts inAction 1-D: Intangible Value at Carlson Hospitality
Carlson Hospitality can use the information from the survey to
determine whether the one-point increase in market share
revenue ($20 million per point) will offset costs associated with
increasing the level of services to high-quality customers which
would result in a 10% increase in customer satisfaction.
Answer to Concepts in Action 1-E: Return on Investment
1. One method for determining a return on investment is to
complete a Cost-Benefit Analysis using the Present Value
Method. Many of the costs for server virtualization are
associated with the initial construction: physical manipulation of
the servers and software licensing. The ongoing costs of labor
in updating and accessing tables would be relatively small.
Using this type of analysis would allow the project sponsors to
show how the benefits of the virtualization would be realized
on a long term basis.
2. Implementing a major change to a system should certainly
include a systems analyst. Systems analysts typically have a
broad view of the system, and would be able to ascertain how
virtualizing the servers will affect the whole system.
