    • 1.2 How Successful Have We Been? Addresses the success of software engineering and the problems associated with it, including examples of software failure.
    • 1.3 What is Good Software? Explores different perspectives on software quality (transcendental, user, manufacturing, product, value-based) and quality models like McCall's.
    • 1.4 Who Does Software Engineering? Identifies the key roles in a software development project: customer, developer, and user.
    • 1.5 System Approach Describes how to build a system from a hardware, software, and people perspective; explains activities, objects, relationships, and system boundaries.
    • 1.6 Engineering Approach Outlines steps to building a system (requirement analysis, system design, program design, writing programs, unit testing, integration testing, system testing, system delivery, and maintenance.
    • 1.7 Members of the Development Team Explains the different roles in a typical software development team: requirement analysts, designers, programmers, testers, trainers, maintenance team, librarians, and configuration management team.
    • 1.8 How Has Software Engineering Changed? Covers changes in software engineering since the 1970s, including Wasserman's seven key factors: time-to-market, shifts in computing economics, powerful desktop computing, extensive networking, object-oriented technology, graphical user interfaces, and the variability of the waterfall model.
    • 1.9 Information Systems Example: Piccadilly System Describes a real-world system (a regional British TV franchise) and constraints on advertising.
    • 1.10 Real Time Example: Ariane-5 Rocket Discusses a real-world example of software failure with a rocket launch failure.
    • 1.11 What this Chapter Means for You Offers implications of software engineering for individuals faced with problem-solving scenarios.
