Quiz 1 Finals (Part 2) Flashcards
Steps in Feasibility Analysis:
- Form a project team and appoint a project leader
- Prepare System Flowchart
- 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
- Prepare and Report the final project directive to management (Feasibility Report)
Involving Future System users in designing and implementing the system is important because their knowledge and experience are crucial for success.
Form a project Team and Appoint a project Leader
Information-oriented charts and data flow diagrams prepared in the initial investigation are also reviewed at this time.
Prepare a system flowchart
this steps identifies the candidate systems that are capable of producing the outputs in the generalized flowcharts. 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 total system requirements;
Enumerate Potential Candidate system
True or False
An important aspect of hardware is processing and main memory. There are a large number of computers with differing processing sizes, main memory capabilities and software support. the project team may contact vendors for information on the processing capabilities of the system available;
True
From the candidate system considered, the team begins preliminary evaluation in an attempt to reduce them to a manageable number.
Describe and identify Characteristics of 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
Each candidate performance is evaluated against the system performance requirements set before the feasibility study.
Determine and evaluate the Performance and Cost-Effectiveness of Each Candidate system.
whatever the criteria, there has to be as close a match as practicable, although trade-offs are often necessary to select the best system,
Determine and Evaluate the Performance and cost-effectiveness of the candidate system
The cost encompasses both designing and installing the system. it include user training, updating the physical facilities and documenting.
Determine and Evaluate the Performance and Cost-effectiveness of Each candidate system.
in some cases, the “___________________” for each candidate system will show which system is the best choice, this outcome terminates the feasibility study
Weight system performance and cost data
the system with the highest total score is judged the best system.
Select the best candidate system
this assumes the weighting factors are fair and the rating of each evaluation criterion is accurate;
Select the best candidate system
The criterion of growth potential is generally given the maximum weight and, thus the greatest effect on the total score. Additionally, system development and user training are also given high weight;
Select the best candidate system
The culmination of the feasibility study is a “______________” directed to management;
Feasibility Report
it evaluates the impact of the proposed changes on the areas(s) in question
Feasibility Report
The report is a formal document for management use, brief enough and sufficiently nontechnical to be understandable, yet detailed enough to provide the basis for system design.
Feasibility Report
There is no standard format for preparing “_____________” . analysts usually decide on a format that suits the particular user and system;
Feasibility Report
Reports contains the following sections:
- Cover Letter
- Table of content
- Overview
4, Detailed Findings - Economic Justification
- Recommendation and conclusion
- Appendixes
Formally Presents the report and briefly indicates to management the nature, General Findings and recommendations to be considered.
Cover Letter
Specifies the location of the various parts of the report
Table of content
is a narrative explanation of the purpose and scope of the project, the reason for undertaking the feasibility study, and the department(s) involved or affected by the candidate system.
Overview
Outline the methods used in the present system.
the system’s effectiveness and efficiency as well as operating cost are emphasized . the section also describes the objectives and general procedures of the candidate system,
Detailed Findings
details point by point cost comparisons and preliminary cost estimates for the development and operation of the candidate system.
return on investment (ROI) analysis of the project is also included.
Economic Justification
suggest to management the most beneficial and cost-effective system.
Recommendation and conclusion
Document all memos and data compiled during the investigation. they are placed at the end of the report for reference.
