System Planning (Preliminary Investigation Overview)
- Mr. Ahmad Al-Ghoul

2. System Analysis and Design System Planning
Learning Objectives
Describe the steps in a preliminary investigation and the end product of an investigation
Avicenna
System Analysis and Design System Planning

3. Preliminary Investigation Overview
Step 3: Perform Fact-Finding
Fact-finding involves various techniques
Depending on what information is needed to investigate the systems request, fact-finding might consume several hours, days, or weeks
Analyze Organization Charts
Obtain organization charts to understand how the department functions
Organization charts show formal reporting relationship but not the informal alignment of a group
Avicenna
System Analysis and Design System Planning

4. Preliminary Investigation Overview
Step 3: Perform Fact-Finding
Conduct interviews
Determine the people to interview.
Establish objectives for the interview.
Develop interview questions.
Prepare for the interview.
Conduct the interview.
Document the interview.
Evaluate the interview.
The purpose of the interview, is to uncover facts, not convince others that the project is justified
In an interview ask effective questions
Include open ended questions
You should interview managers and supervisors who have a broad knowledge of the system
You might talk to operational personal to learn how the system functions on day-to-day basis
Avicenna

5. Preliminary Investigation Overview
Step 3: Perform Fact-Finding
Review documentation
To learn more about the current system
Observe operations
To see how workers carry out typical tasks
To follow the actual paths taken by input source documents or output reports
Conduct a user survey
To get information from a larger group
Design a form that users complete
It is not flexible as interview
Less expensive, less time, and can involve a broad cross-section of people
Avicenna

6. Preliminary Investigation Overview
Step 4: Evaluate Feasibility
Evaluate the project’s operational, technical, economic, and schedule feasibility
Avicenna
System Analysis and Design System Planning

7. Preliminary Investigation Overview
Step 5: Estimate Project Development Time and Cost
What information must you obtain, and how will you gather and analyze the information?
What sources of information will you use, and what difficulties will you encounter in obtaining information?
Avicenna
System Analysis and Design System Planning

8. Preliminary Investigation Overview
Step 5: Estimate Project Development Time and Cost
Will you conduct interviews? How many people will you interview, and how much time will you need to meet with the people and summarize their responses?
Will you conduct a survey? Who will be involved? How much time will it take people to complete it? How much time will it take to prepare it and tabulate the results?
Avicenna
System Analysis and Design System Planning

9. Preliminary Investigation Overview
Step 5: Estimate Project Development Time and Cost
How much will it cost to analyze the information gathered and to prepare a report with findings and recommendations?
You should provide an estimate for the overall project, so managers can understand the full cost impact and timetable
Avicenna
System Analysis and Design System Planning

10. Preliminary Investigation Overview
Step 6: Present Results and Recommendations to Management
The final task in the preliminary investigation is to prepare a report to management
The format of the preliminary investigation report varies from one company to another
The report includes an evaluation of system request, an estimate of costs and benefits, and your recommendation
Avicenna
System Analysis and Design System Planning

11. Preliminary Investigation Overview
Step 6: Present Results and Recommendations to Management
Introduction
It contains a brief description of the system, the name of the person or group who performed the investigation, and the name of the person or group who initiated the investigation
Systems request summary
It describes the basis of the system request
Findings
It contains the results of the preliminary investigation
Recommendations
Recommendations for further action, with specific reasons and justification
Avicenna
System Analysis and Design System Planning

12. Preliminary Investigation Overview
Step 6: Present Results and Recommendations to Management
Project Roles
Lists the people who will participate in the project, and describes each person’s role
Time & cost estimates
This section describes the cost of acquiring and installing the system, and the total cost of ownership during the system’s useful life
Expected benefits
Anticipated tangible and intangible benefits and a timetable that shows when they are to occur
Appendix
It included in the report for supporting information
Avicenna

Sequence Summary
During the third step in preliminary investigation, the analyst perform fact-finding
Fact-finding involves various techniques such as Analyze Organization Charts, interviews, Review documentation, and Conduct a user survey
During the fourth step in preliminary investigation, the analyst evaluate the project’s operational, technical, economic, and schedule feasibility
During the fifth and sixth steps, the analyst estimate project development time and cost; and present results and recommendations to management
