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 youan introduction to some of the major techniquesand models that will be taught
later in the text.Please be aware that most projects especially large complex projects take
weekssometimes 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 systemcase.
Iassume that the studentsin this class have various levels ofsystems development background. So
you maynot have allofthe skills necessary to do an error-free complete developmentassignment. The
objective of the case and its assignmentsis simply to allow youto practice going through the entire
development process so that youobtain 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 forwhether 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
submittedit last minute, did the minimumjust to submit something by the deadline, and/or you did a
sloppy job. Trust me I can tell.I suggest that you submit the assignmentearly with your best effort. If
there’s time and I think you can improve on your work, then I will allow for resubmissionfor 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 datethen most likely I will NOT allow for resubmission.I want to mentor you
throughthe 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 attachyour file(s).I will help you out. Systems Analysis and Design in a Changing World,

, Learning Objectives
After reading this chapter, youshould 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
The objective of this section is to introduce youto the basic concepts of a computer applicationand
an information system. The section includes an introduction to and definition of systems analysis
and design and explains how it fits into the process of developing a new information system, i.e.
systems development. Systems analysismeans to understand whatthe system must do. Systems
designmeans to specify howthe components are configured to provide the solution.
Systems Development Life Cycle
Key Terms
project—a planned undertaking that has a beginning and an end, and that produces some definite
result
Systems Development Life Cycle (SDLC)—the entire process consisting of all the activities
required to build, launch, and maintain an information system
information systems development process—the actual approach used to develop a particular
information system
Agile Development—an information systems development process that emphasizes flexibility
