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

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

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

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 System Analysis and Design System Planning

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 System Analysis and Design System Planning

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

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

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

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

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

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

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 System Analysis and Design System Planning

System Analysis and Design System Planning 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 Avicenna System Analysis and Design System Planning

System Analysis and Design System Planning Sequence Summary In this Sequence we have Described the third step in preliminary investigation that describe how to perform fact-finding Described the interviews technique Defined other fact finding techniques, document review, user observation, and survey Described the fourth step in preliminary investigation that describe how to evaluate feasibility Described the fifth step in preliminary investigation that describe how to estimate project development time and cost Described The final task in the preliminary investigation that describe how to prepare a report to management Avicenna System Analysis and Design System Planning
