Chapter1:The Systems Analyst and Information Systems Development
AnswertoYourTurn1-1:BeinganAnalyst
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.
AnswertoYourTurn1-2:Implementinga SatelliteData 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.

information on employee injury claims.
Business Requirements Automated system which allows for 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

AnswertoYourTurn1-4:Too Much Paper,Part2
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.
Answerto ConceptsinAction 1-A:AnArrayof ITFailures
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.
Answerto ConceptsinAction 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.
