Chapter 1Modern Systems Analysis and Design 8th editionInstructor’s Manual1Chapter 1The Systems Development EnvironmentChapter OverviewChapter 1 is an overview of the systems development process, as well as an overview of the textbook.This chapter introduces students to the modern approach to systems analysis and design using variousmethodologies.Students are introduced to several systems development components, including theprocess and data-oriented approaches to systems development; different types of information systems;and the systems development life cycle.This textbook is intended primarily for juniors taking a core course in the information systems major,although the book can be adapted for a similar course at the junior college level or for a two-coursesequence on analysis and design. Often students are not familiar with the systems developmentprocess, different organizational components, or how these components work together. This chapterprovides the general organizational context in which systems development takes place.The text uses the Systems Development Life Cycle (SDLC) methodology (including its associatedproblems with the traditional waterfall approach) to introduce students to the structured approach increating new systems. The student is also introduced to other methodologies such as Computer-AidedSystems Engineering (CASE), the Agile Methodologies, eXtreme Programming, Object OrientedAnalysis and Design (OOAD), and the Rational Unified Process (RUP).The text compares andcontrast the new with more traditional methods in an effort to show both the advantages andlimitations of these methods.Chapter 1 introduces students to CASE usage in organizations, CASE components, and visual andemerging development tools. CASE tools are used to apply an engineering approach to systemsdevelopment and can support each phase of the SDLC. The purpose of CASE is to make it easier foran organization to enact a single design philosophy across many projects, systems, and stakeholders.CASE provides support for all SDLC activities.Instructional ObjectivesSpecificstudentlearningobjectivesareincludedatthebeginningofthechapter.From an instructor’s point of view, the objectives of this chapter are to:1.Defineanddiscussthemodernapproachtosystemsanalysisanddesignfromanorganizational perspective incorporating techniques, tools, and methodologies.2.Explain how an organization’s objectives, structure, and processes are essential in thedevelopment of systems to meet their needs.3.Explain that the SDLC process is not sequential but cyclical and that the order is adaptable asrequired for different projects; also to emphasize that often analysts and designers may gobackwards to the previous step to complete unfinished products or to correct errors oromissions discovered in the next phase.
