Information Systems Development

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:

• 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.

• 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.

System Request

Element Description Sponsor Document Manager.Business Need Increase efficiency in storing, updating, and retrieving 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 are treated according to regulations.

Answer to Your Turn 1-4: Too Much Paper, Part 2

• 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.

• 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.

Answer to Concepts in Action 1-A: An Array of IT Failures

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. 3 / 4

Answer to Concepts in Action 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 in Action 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

• 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.

• 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.
