Chapter 1 - From Beginning to End: An Overview of Systems Analysis and Design Lecture Notes Table of Contents  Chapter Overview  Learning Objectives Chapter Overview The sixth edition of Systems Analysis and Design in a Changing World is a completely new and innovative approach to teaching systems analysis and design. The intent of this new approach is to provide a much more example based learning opportunity. As such the entire first chapter is an example of a complete development project from beginning to end. Obviously, in a single chapter example, not every step is elaborated. However, by going through the entire process, you will be able to obtain a broad overview and a clear perspective of the entire development process. The chapter first introduces several basic concepts that are needed to understand systems development. The first few sections define Systems Analysis, Systems Design, the Systems Development Life Cycle (SDLC), iterative development, Agile development and the six core processes of systems development. The remainder of the chapter illustrates the first iteration of a typical development project for the Ridgeline Mountain Outfitters (RMO) Tradeshow system. It divides the project into seven steps, including pre-project activities and then six other development steps. For simplicity purposes, each step is assigned a day, so the project has Day 1 activities, Day 2 activities, etc. Throughout this set of daily activities, all six core processes are explained and illustrated. Sample models and diagrams are presented to give you an introduction to some of the major techniques and models that will be taught later in the text. Please be aware that most projects especially large complex projects take weeks sometimes months even years. The book is just making it simpler by presenting it by days. Your assignments will be to work on a running case similar to the RMO Tradeshow system case. I assume that the students in this class have various levels of systems development background. So you may not have all of the skills necessary to do an error-free complete development assignment. The objective of the case and its assignments is simply to allow you to practice going through the entire development process so that you obtain a solid overview of systems development. My philosophy on grading is that you must give it your best effort. I am not looking for perfect submissions. I am looking for whether you read the book, understood the concepts, tools, techniques enough to apply them to the case assignment. I will know if you did not give it your best effort. Meaning you submitted it last minute, did the minimum just to submit something by the deadline, and/or you did a sloppy job. Trust me I can tell. I suggest that you submit the assignment early with your best effort. If there’s time and I think you can improve on your work, then I will allow for resubmission for more points. It is completely at my discretion whether I will allow you to resubmit the assignment or not. If it is on the due date then most likely I will NOT allow for resubmission. I want to mentor you through the case study. Don’t be shy about sending me questions if you are confused. This is NOT a license for me to review your work before you submit and do pre-grading. Be specific about your question(s) and attach your file(s). I will help you out. Systems Analysis and Design in a Changing World, sixth edition 1-2 Learning Objectives After reading this chapter, you should be able to:  Describe the purpose of systems analysis and design in the development of information system  Describe the characteristics of iterative systems development  Explain the six core processes of the Systems Development Life Cycle  Identify key documents that are used in planning a project  Identify key diagrams used in systems analysis and systems design  Explain the utility of identifying use cases in systems development  Explain the utility of identifying object classes in systems development Software Development and Systems Analysis and Design Key Terms  computer application (app)—a computer software program that executes on a computing device to carry out a specific function or set of related functions  information system—a set of interrelated computer components that collects, processes, stores, and provides as output the information needed to complete business tasks  systems analysis—those activities that enable a person to understand and specify what the new system should accomplish  systems design—those activities that enable a person to define and describe in detail the system that solves the need
