M3S1 Feasibility Study Flashcards
phase that results in the completion of various activities:
- An initial investigation.
- Recognition of need.
- Determination of user requirements.
- Verification of objectives, constraints, required outputs & required inputs
Project selection
Identification, description & evaluation of the candidate system, and finally selection of the best system for the job.
Feasibility Study
Carried out to select the best system that meets performance requirements.
Feasibility Study
Recommends the most effective system to the management.
Feasibility Study
Ensures that the business will benefit: operational, technical and financial benefits
Feasibility Study
Describes the expected performance of a candidate system
System Performance Definition
Contains a detailed description of the system’s output in a user-acceptable format
System Performance Definition
Three Steps of System Performance Definition
- Statement of constraints.
- Identification of specific system objectives.
- Description of outputs.
States the system’s benefits and then translates them into measurable objectives
Identification of Specific System Objectives
A description of the factors that limit the solution of the problem that has a bearing on the required performance of a candidate system.
Statement of Constraints
Different Constraints
Time Constraints
Budget Constraints
User Constraints
Compliance/Regulatory Constraints
Technical Constraints
factors that limit the solution of the problem
Constraints
Where specific goals meet specific benefits
Identification of Specific System Objectives
The result of the fact-finding phase of the initial investigation is revealed in the _________.
Statement of Constraints
Once the constraints are spelled out, the analyst proceeds to the ______________________
Identification of Specific System Objectives
Objectives has to be SMART and quantifiable, with numbers and percentages
Identification of Specific System Objectives
Derived from the general objectives specified in the project directive at the end of the initial investigation.
Identification of Specific System Objectives
A final step in system performance definition is _________________________
describing the output required by the user.
Describing the output required by the user.
Description of Outputs
Where you produce tangibles and deliverables
Description of Outputs
Tangibles and Deliverables to Evaluate the Feasibility of Candidate Systems
Performance Metrics Report
Error Reduction Report
User Feedback Survey Results
System Load Test Results
Compliance Certification
A detailed report showing the improvement in registration times, system uptime, and peak load handling capabilities.
Performance Metrics Report
Surveys to measure user satisfaction rate with the new system interface and overall experience.
User Feedback Survey Results
Documentation and analysis showing the reduction in data entry errors before and after the system enhancements.
Error Reduction Report
Evidence and documentation proving the system’s compliance with relevant data privacy regulations.
Compliance Certification
Reports from simulated peak load tests demonstrating the system’s ability to handle increased traffic without performance issues.
System Load Test Results
Three Feasibility Considerations
Economic Analysis/ Economic Feasibility
Technical Feasibility
Behavioral Feasibility
The most frequently used method for evaluating the effectiveness of a candidate system.
Economic Analysis/ Economic Feasibility
Commonly known as cost/benefit analysis.
Economic Analysis/ Economic Feasibility
To what extent existing computer system can support the proposed addition.
Technical Feasibility
All about the existing computer system (hardware, software, etc.)
Technical Feasibility
People tend to resist change, while computers can facilitate it.
Behavioral Feasibility
How people will react to change, particularly when introducing a computerized system.
Behavioral Feasibility
8 Steps in Feasibility Analysis
- Form a project team and appoint a project leader.
- Prepare system flowcharts.
- Enumerate potential candidate systems.
- Describe and identify characteristics of candidate systems.
- 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 project directive to management
The concept behind a project team is that future system users should be involved in its design and implementation;
Form a project team and appoint a project leader.
More complex studies require a _____________
project team
For small projects, the________ and an_________ usually suffice
analyst and assistant
Their knowledge and experience in the operations area are essential to the success of the system.
Form a project team and appoint a project leader.
Professionals with enough collective expertise to devise a solution to the problem
analysts and user staff
project team consist of
analysts
user staff
outside consultant
information specialist
prepare generalized system flowcharts for the system.
Prepare system flowcharts
Information–oriented charts and data flow diagrams prepared in the initial investigation are also reviewed at this time.
Prepare system flowcharts
identifies the candidate systems that are capable of producing the outputs included in the generalized flowcharts.
Enumerate potential Candidate System
This requires a transformation from logical to physical system models;
Enumerate potential Candidate System
Another aspect of this step is consideration of the hardware that can handle the total system requirements;
Enumerate potential Candidate System
An important aspect of hardware is __________ and ____________.
processing and main memory.
The project team may contact vendors for information on the processing capabilities of the system available;
Enumerate potential Candidate System
Technical knowledge and expertise in the hardware/software area are critical for determining what each candidate system can and cannot do.
Describe and Identify Characteristics of Candidate System
In some cases, the performance and cost data for each candidate system will show which system is the best choice. This outcome terminates the feasibility study;
