18
Q

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

A
  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?
19
Q

Feasibility Considerations:

A
  1. Economic Feasibility
  2. Technical Feasibility
  3. Behavioral Feasibility
20
Q

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

A

Economic Feasibility

21
Q

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.

A

Economic Feasibility

22
Q

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

A

Technical Feasibility

23
Q

this involves financial considerations to accommodate technical enhancements.

A

Technical Feasibility

24
Q

Hesitant to change

A

Behavioral Feasibility

25
Q

Steps in Feasibility analysis:

A
  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
26
Q

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.

A
  1. Form a project team and appoint a project leader
27
Q

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.

A
  1. Prepare a system flowchart
28
Q

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.

A
  1. Enumerate Potential candidate system
29
Q

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.

A
  1. Describe and identify the characteristics of the candidate system
30
Q

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

A
  1. Determine and evaluate the performance and the cost-effectiveness of each candidate system.
31
Q

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.

A
  1. Weigh System performance and cost data
32
Q

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.

A
  1. Select the best candidate system
33
Q

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.

A
  1. Feasibility Report
