PART II

SCENARIOS THROUGH THE SYSTEM LIFECYCLE: TECHNIQUES

OVERVIEW OF PART 2—TECHNIQUES

INTRODUCTION

This part of the book consists of a set of chapters written by authors with expertise in different scenario-based techniques. Each chapter can stand alone as an introduction to a technique; but the chapters follow a common framework, explained below, and authors have where appropriate, drawn comparisons between their own and other techniques, especially those described in other chapters. Therefore, there are several ways of using this part of the book, other than simply reading it from start to end,

  • find the chapters that describe the techniques you are most interested in, and study those in detail;
  • read the Summaries of all the chapters to get an idea of the range of techniques;
  • skim through the chapters, especially the Strengths and Weaknesses and Comparisons sections, to get an appreciation of the relative merits of the techniques.
