Objectives of this Book This book is an introduction to a set of software specification methods. Its tar­ geted audience are readers who do not wish to read pages of definitions in order to understand the basics of a method. The same case study is used to introduce each method, following a rigorously uniform presentation format. Special care has been devoted to ensure that specifications do not deviate from the case study text. As much as the method allows, what is specified is what appears in the case study text. The benefits are two-fold. First, the reader can easily switch from one method to another, using his knowledge of the case study as a leverage to understand a new method. Second, it becomes easier to compare methods, because the same behavior is specified in each case. Each method presentation follows the same pattern. The concepts are pro­ gressively introduced when they are needed. To illustrate the specification pro­ cess, questions that the specifier should raise during the analysis of the case study are stated. Answers are provided as if they were given by an imaginary client. The question/answer process guides the derivation of the specification. Interestingly, the questions raised depend on the method, which is illustrative of the differences between them.

This volume provides the formal methods practitioner with a survey of the key software specification methods. Each technique is demonstrated using the same case study - an invoicing system - to enable the reader to compare and contrast easily. Among the techniques covered are: UML, Z, SAZ, B, JSD, OMT, VHDL, Estelle, SDL and LOTOS. Most specification courses tend to focus on one or two key techniques and to have a theoretical bias this book provides a basic overview of the main methods, and has a practical focus that allows the reader to apply their knowledge to real-life situations. It hopes to prove to be useful reading for all industrial and commercial practitioners who need to expand their knowledge of software specification methods.
