Phase 1: Systems Planning Chapter 2 Analyzing the Business case
Phase Description • Systems planning is the first of five phases in the systems development life cycle (SDLC) • In this phase, you will learn how IT projects get started and how a systems analyst evaluates a proposed project and determines its feasibility
Introduction • The term business case refers to the reasons, or justification, for a proposal • To analyze the business case, the analyst must consider: • Company’s overall mission • Objectives • IT needs
Strategic Planning • IT team must understand, support, and help plan strategic goals • Strategic planning is the process of identifying long-term organizational goals, strategies, and resources • Strategic Planning Overview • SWOT analysis Figure2-2
Strategic Planning • From Strategic Plans to Business Results • Mission statement • Stakeholders • Goals • Objectives Figure2-3
Information Systems Projects • Reasons for Systems Projects • Systems request • Improved service • Better performance • More information • Stronger controls • Reduced cost
Information Systems Projects • Factors that Affect Systems Projects • Internal and external factors affect every business decision that a company makes, and IT systems projects are no exception Figure2-8
Information Systems Projects • Project Management Tools • All IT projects, large and small, must be managed and controlled • E.g. MS Project • Define tasks activities, participants, work sequence, etc • Project management begins with a systems request, and continues until the project is completed or terminated
Evaluation of Systems Requests • Systems review committee or a computer resources committee evaluate systems projects • Systems Requests Forms • A properly designed form streamlines the request process and ensures consistency Figure2-12
Evaluation of Systems Requests • Systems Review Committees • Most large companies use a systems review committee to evaluate systems requests • Many smaller companies rely on one person to evaluate system requests instead of a committee • The goal is to evaluate the requests and set priorities
Overview of Feasibility • A systems request must pass several tests, called a feasibility study, to see whether it is worthwhile to proceed further • Operational Feasibility • Operational feasibility • Technical feasibility • Economic Feasibility • Schedule Feasibility Figure2-13
Evaluating Feasibility • The first step in evaluating feasibility is to identify and weed out systems requests that are not feasible • Even if the request is feasible, it might not be necessary • Feasibility analysis is an ongoing task that must be performed throughout the systems development
Setting Priorities • Discretionary and Nondiscretionary Projects • Projects where management has a choice in implementing them are called discretionary projects • Projects where no choice exists are called nondiscretionary projects
Preliminary Investigation Overview • Preliminary investigation • Interaction with Managers and Users
Preliminary Investigation Overview • Planning the Preliminary Investigation
Preliminary Investigation Overview • Step 1: Understand the Problem or Opportunity • Determine which departments, users, and business processes are involved • A popular technique for investigating causes and effects is called a fishbone diagram, or Ishikawa diagram Figure2-17
Preliminary Investigation Overview • Step 2: Define the Project Scope and Constraints • Project scope • Payroll is not produced accurately • Payroll is not calculated correctly for production workers on the 2nd shift at Yorktown plant • Avoid Project creep • Constraint • Present vs. future • Internal vs. external • Mandatory vs. desireable Figure2-18
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 Figure2-19
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.
Preliminary Investigation Overview • Step 3: Perform Fact-Finding • Review documentation • Observe operations • Conduct a user survey
Preliminary Investigation Overview • Step 4: Evaluate Feasibility • Evaluate the project’s operational, technical, economic, and schedule feasibility
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?
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?
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
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
Preliminary Investigation Overview • Step 6: Present Results and Recommendations to Management • Introduction • Systems request summary • Findings • Recommendations • Time & cost estimates • Expected benefits • Appendix Figure2-21
