Chapter 4 - Systems analysis. After studying this chapter you will be able to: Define systems analysis and relate it to the scope definition, problem analysis, requirements analysis, logical design, and decision analysis phases; describe a number of systems analysis approaches for solving business system problems; describe scope definition, problem analysis, requirements analysis, logical design, and decision analysis phases in terms of information system building blocks;. | Chapter 4 Systems Analysis This repository of slides is intended to support the named chapter. The slide repository should be used as follows: Copy the file to a unique name for your course and unit. Edit the file by deleting those slides you don’t want to cover, editing other slides as appropriate to your course, and adding slides as desired. Print the slides to produce transparency masters or print directly to film or present the slides using a computer image projector.

Describe scope definition, problem analysis, requirements analysis, logical design, and decision analysis phases in terms of purpose, participants, inputs, outputs, techniques, and steps. Identify those chapters in this textbook that can help you learn specific systems analysis tools and techniques. Teaching Notes Although some of the tools and techniques of systems analysis are previewed in this chapter, it is not the intent of this chapter to teach those tools and techniques. This chapter teaches only the process of systems analysis. The tools and techniques will be taught in the subsequent six chapters. What is Systems Analysis ? Systems analysis – a problem-solving technique that decomposes a system into its component pieces for the purpose of studying how well those component parts work and interact to accomplish their purpose. Systems design – a complementary problem-solving technique (to systems analysis) that reassembles a system’s component pieces back into a complete system—hopefully, an improved system. This may involves adding, deleting, and changing pieces relative to the original .
