Answer 16

Compliance Certification

Question 17

Reports from simulated peak load test demonstrating the system’s ability to handle increased traffic without performance issue

Answer 17

System Load test result

Question 18

If the feasibility study is to serve as a decision document it must answer three key questions:

Answer 18

1. is there a new and better way to do the job that will benefit the user?
2. What are the cost and saving of the alternatives?
3. what is recommended?

Question 19

Feasibility Considerations:

Answer 19

1. Economic Feasibility
2. Technical Feasibility
3. Behavioral Feasibility

Question 20

this is the most frequently used method for evaluating the effectiveness of a candidate system.

Answer 20

Economic Feasibility

Question 21

more commonly known as cost/benefit analysis, the procedure is determine the benefits and savings that are expected from a candidate system and compare them with cost.

Answer 21

Economic Feasibility

Question 22

centers around the existing computer system (hardware, software, etc.) and to what extent it can support the proposed addition.

Answer 22

Technical Feasibility

Question 23

this involves financial considerations to accommodate technical enhancements.

Answer 23

Technical Feasibility

Question 24

Hesitant to change

Answer 24

Behavioral Feasibility

Question 25

Steps in Feasibility analysis:

Answer 25

1. Form a project team and appoint a project leader 2. Prepare system flowchart 3. enumerate potential candidate system 4. describe and identify the characteristics of the candidate system 5. determine and evaluate the performance and cost-effectiveness of the candidate system. 6. weight system performance and cost data 7. select the best candidate system 8. Feasibility Report

Question 26

what steps in feasibility is this? -Future system users should help design and implement the system. -Their knowledge and experience are crucial for success. -Small projects can be handled by an analyst and an assistant. -Complex projects need a larger team of analysts and user staff with the necessary expertise. -Sometimes, an outside consultant and an information specialist join the team until the project is finished.

Answer 26

1. Form a project team and appoint a project leader

Question 27

what steps in feasibility is this? -The next step in the feasibility study is to create general system flowcharts. -Review information-oriented charts and data flow diagrams from the initial investigation.

Answer 27

2. Prepare a system flowchart

Question 28

what steps in feasibility is this? -Find systems that can produce the outputs shown in the flowcharts by changing logical models to physical ones. -Check hardware that can meet the system's needs. -Look at the processing power and memory of available computers, which differ in size, memory, and software. -The project team can ask vendors about the processing capabilities of their systems.

Answer 28

3. Enumerate Potential candidate system

Question 29

what steps in feasibility is this? -Begin a preliminary evaluation to narrow down the candidate systems to a manageable number. -Use technical knowledge and expertise to understand the capabilities and limitations of each candidate system.

Answer 29

4. Describe and identify the characteristics of the candidate system

Question 30

what steps in feasibility is this? -Evaluate each system's performance against the requirements set before the feasibility study. -Aim for a close match, though trade-offs may be needed to select the best system. -Consider the total cost, including design, installation, user training, facility updates, and documentation

Answer 30

5. Determine and evaluate the performance and the cost-effectiveness of each candidate system.

Question 31

what steps in feasibility is this? -Sometimes, the performance and cost data clearly show the best system, ending the feasibility study. -Often, the best system isn't clear. In such cases, assign ratings to each criterion to determine the most important factors. -Select the candidate system with the highest total score.

Answer 31

6. Weigh System performance and cost data

Question 32

what steps in feasibility is this? -The system with the highest total score is chosen as the best. -This assumes fair weighting and accurate rating of each evaluation criterion. -Growth potential usually has the highest weight, followed by system development and user training.

Answer 32

7. Select the best candidate system

Question 33

what steps in feasibility is this? -The feasibility study ends with a report for management. -It assesses the impact of the proposed changes on the relevant areas. -The report should be clear and concise for management, but detailed enough for system design. -There is no standard format; the format is chosen based on the user and system.
