Quiz 1 (Redo) Finals FEASIBILITY STUDY Flashcards
The Project Selection phase is over resulting in completion of various activities:
- Recognition of needs
- Determination of User Requirements
- An initial investigation
- Verification of Objectives, Constraints, and required input and output
The next step is determine exactly what the candidate system is to do by defining its expected performance.
Feasibility Study
Carried out to select the best system that meets the performance requirements
Feasibility Study
It comprises of identification, description and evaluation of the candidate system, and finally selection of the best system for the job.
Feasibility Study
Recommends to the management either the most effective system or concludes that the system may not be evolved.
Feasibility Study
Defined by describing its output in a user acceptable format and at a higher detail than what was described in the initial investigation.
System Performance Definition
System Performance Definition has 3 steps:
- Statement of Constraints
- Identification of Specific System Objectives
- Description of Output
These are the factors that limits the solution of the problem.
Constraints
They are derived from the general objectives specified in the project directive at the end of the initial investigation.
Identification of specific system objectives
The step states the system benefits and then translate them into measurable objectives.
Identification of Specific system objectives.
A final step on System Performance Definition.
Description of Output
When the analyst is ready to evaluate the feasibility of candidate system it should produce these outputs: (Description of Output)
- Performance Metric Report
- User Feedback Survey Results
- Error Reduction report
- Compliance Certification
- System load test results
A detailed report the improvement in registration time, system uptime, and peak load handling capabilities
Performance Metric Report
Surveys from student and staff reflect the user satisfaction rate with the new system interface and overall experience.
User feedback survey results
Documentation and analysis showing the reduction data entry errors before and after system enhancement
Error Reduction report
Evidence and documentation proving the system’s compliance with relevant data privacy
Compliance Certification
Report from simulated peak load tests demonstrating the system ability to handle increased traffic without performance issues.
System Test load Result
If the feasibility study is to serve as decision document it must answer three questions:
- Is there a new and better way to do the job that will benefit the user?
- What are the cost and savings of the alternative(s)?
- What is recommended?
The Feasibility Considerations
- Economic Feasibility
- Technical Feasibility
- Behavioral Feasibility
This is the most frequently used method for evaluating the effectiveness of a candidate system.
Economic Feasibility
More commonly known as cost/benefit analysis, the procedure is to determine the benefits and savings that are expected from a candidate system and compare them with cost.
Economic Feasibility
Centers around the exising computer system (Hardware, software, etc) and to what extent can support the proposed addition
Technical Feasibility
Hesitant to change
Behavioral Feasibility
Steps in Feasibility analysis
- Form a project team and appoint project leader.
- Prepare sa system flowchart
- Enumerate potential candidate system
- Describe and identify characteristics of candidate system
- Determine and evaluate the performance and cost-effectiveness of each candidate system
- Weight system performance and cost data
- Select the best candidate system
- Prepare and report the final projecy directive to management (Feasibility Report)
