1

What are the five major project fundamentals?

  1. Project initiation - defining a problem
  2. Determining project feasibility
  3. Activity planning and control
  4. Project scheduling
  5. Manging systems analysis team members

-Ch 3, pp. 92-93

2

List three ways to find out about problems or opportunities that might call for a systems solution.

  1. Check output against performance criteria.
  2. Observe behavior of employess.
  3. Listen to external feedback from: Vendors, service providers, customers, and superiors.

-Ch 3, pp. 48

3

List the five criteria for sytems project selection.

  1. Management backing
  2. Appropriate timing for resource commitment
  3. Moves the business toware attainment of its goals
  4. Practical
  5. Important enough to be considered over other possible projects

-Ch 3, pp. 93

4

Define technical feasibility.

The first part of resource determination, assesses whether it is possible to develop a new system given the current technical resources. The output is deciding whether to add to the present system and whether or not technology is available to meet the user's needs.

-Ch 3, pp. 53-54

 

5

Define economic feasibility.

The second part of resource determination, assesses the short and long-term cost-benefit of developing a new system. Variables include analyst's time, cost of system study, cost of employees' time for study, estimated cost of hardware and software. 

-Ch 3, pp. 54

6

Define operational feasibility.

The third and final part of resource determination, assesses if the system will operate and be used once it is put into service. Also looks at the human resources available to complete the project. 

-Ch 3, pp. 54

7

List four criteria for evaluting system hardware.

  1. The time reequired for average transactions (including how long it takes to input data an receive an output)
  2. The total volume capacity of the system (how much can be processed at the same time before a problem arises)
  3. The idle time of the CPU or network
  4. The size of the memory provided

-Ch 3, pp. 57

8

What two main options do organizations have for acquiring or using computer hardware?

  1. Buying hardware
  2. Using cloud services

-Ch 3, pp. 58

9

What does COTS stand for?

Commercial Off-the-Shelf: Refers to already packaged and thoroughly tested software. Examples range from Enterprise (ERP) deployments to MS Office Suite.

-Ch 3, pp. 61

10

List five of the many benefits of cloud computing for organizations.

  1. Maintenance and upgrades performed by the provider
  2. Ability to change software and hardware rapidly
  3. Scalable
  4. Consistent over multiple platforms
  5. No capital is tied up (consider the capital investment you skip by dropping SDLC Step 5, Developing and Documenting the Software)

-Ch 3, pp. 58

11

List three of the many drawbacks of cloud computing for organizations.

  1. Company doesn't control its own data
  2. Data security is at risk
  3. Reliability risk of the Internet platform
  4. Proprietary APIs and software may make switching providers difficult

-Ch 3, pp. 58

12

What does BYOD stand for?

Bring Your Own Device: A corporate policy that permits employees to use their preferred personal mobile technology (For example, their mobile phone or tablet) for work purposes once the technology undergoes customization by the corporate IT department, which uploads work software, encryption for security purposes, and so on to prepare the device for work.

-Ch 3, pp. 501

13

 What are the benefits of BYOD to an organization?

  1. Potential for lowering and organization's hardware purchases
  2. Facilitates remote 24/7 access to the corporate computer network

-Ch 3, pp. 60

14

What are the benefits of BYOD to an employee?

  1. Building employee morale
  2. Facilitates remote 24/7 access to the corporate computer network
  3. Builds on a familiar user interface

-Ch 3, pp. 60

15

What is the biggest drawback of BYOD for an organization?

Security risks posed by untrained users.

-Ch 3, pp. 60

16

What are the three main categories of cloud computing?

  1. SaaS: Software as a Service
  2. IaaS: Infrastructure as a Service
  3. PaaS: Platform as a Service

-Ch 3, pp. 93

17

Define tagible costs and tangible benefits. Give examples of each.

Tangible Costs: The costs in dollars that can be accurately projected by a systems analyst, including the cost of computers, resources, analyst' and programmer's time, and other employees' salaries, to develop a new system.

Tangible Benefits: Advantages measurable in dollars that accrue to an organization through the use of information systems.

-Ch 3, pp. 507

18

Define intangible costs and intangible benefits. Give examples of each.

Intangible Costs: Costs that are difficult to estimate and may not be known, including losing a competitve edge, losing a reputation for innovation, and declining company image, due to untimely or inaccessible information.

Intangible Benefits: Benefts that accrue to an organization as a result of a new information system and that are difficult to measure, such as improving decision making, enhancing accuracy, and becoming more competitive.

-Ch 3, pp. 504

19

List four techniques for comparing the costs and benefits of a proposed system.

  1. Break-Even Analysis
  2. Payback
  3. Cash-Flow Analysis
  4. Present Value Analysis

-Ch 3, pp. 66

20

When is break-even analysis useful?

When the project needs to be justified in terms of cost, not benefits, or if benefits do not substantially improve with the proposed system. 

-Ch 3, pp. 69

21

What are the three drawbacks of using the payback method?

Answer needed, not outlined in text

22

When is cash-flow anlaysis useful?

When the project is expensive relative ot the size of the company or when the business would be signficantly affected by a large drain (even if temporary) on funds.

-Ch 3, pp. 69

23

As a general guideline, when shoud present value analysis be used?

When the payback period is long or when the cost of borrowing money is high.

Present Value: The total amount that a series of future payments is worth now; a way to assess the economic outlays and revenues of the information system over its economic life and compare costs today with future benefits.

-Ch 3, pp. 69, 506

24

What is work breakdown structure (WBS), and when should it be used?

Work Breakdown Structure: A system of breaking down a project into simpler tasks, usually by decomposition. A WBS can be either product or process oriented. Information systems projects to be process oriented.

-Ch 3, pp. 508

25

What is a Gannt chart?

Gantt Chart: A graphical representation of a project that shows each task activity as a horizontal bar, the length of which is proportional to its time for completion.

-Ch 3, pp. 504

26

When is a PERT diagram usefuel for system projects and what does it stand for?

Program Evaluation Review Technique (PERT) Diagram: A tool used to determine critical activities for a project. It can be used to improve a project schedule and evaluate progress.

-Ch 3, pp. 505 

27

List three advantages of using a PERT diagram over a Gantt chart fo scheduling systems projects.

28
Correlates to PERT

Define the term critical path.

Critical Path: The longest path calculated using the PERT scheduling technique; the path that will cause the whole systems project to fall behind if even on day's delay is encountered on it.

-Ch 3, pp. 502
