Opis

This book brings together for the first time two important features of a computer system that must be embedded in an organisational context. First comes responsibility, in other words, whether the computer system properly supports the organisational responsibilities that people are allocated. Second, the book examines dependability, which means whether the system supports those responsibilities in a trustworthy fashion. Aimed at researchers and doctoral students, the work pays particular attention to looking at what happens when things go wrong.

Recenzje

From the reviews:

"Unique consideration of social and human factors in designing responsibility and dependability into complex systems makes this treatise appropriate for system engineers, social scientists, and graduate students. ... Responsibility modeling is discussed in detail, and useful tools are presented for the analysis and technical design of complex systems. ... The book is an appropriate length, and contains a good index and list of references ... . I recommend this book ... ." (Brad Reid, Computing Reviews, January, 2008)

It is a truism that ‘human error’ is a common reason for failure in complex systems. These ‘errors’ sometimes lead to system failures because designers have failed to consider the normal human tendency to make mistakes. In other cases, ‘errors’ arise because of misunderstandings of who is responsible for what and how these responsibilities are to be discharged. Responsibility failures lead directly to actions that result in system failure.

Responsibility and Dependable Systems is the first book to examine the relationship between responsibility and system dependability. Both editors have backgrounds in computing and social science giving them a unique insight into how responsibility influences system dependability in different environments.

Divided into three parts, the first considers the philosophical and social aspects of responsibility, revisiting socially oriented system failures from a social, ethnographic perspective to tease out the complexities of the responsibilities that were implicated in the failure. Part Two uses a series of simple modelling notations to consider responsibility from a process and role-oriented perspective, using ideas from computer science, social science, management theory and engineering. The final section introduces new methods for analysing responsibility and mapping responsibilities within an organisation. The methods are illustrated by annotated models that can be adapted for use in both analysing and preventing failures of responsibility.

Systems engineers, computer scientists, social scientists, ergonomists and management researchers will all benefit from reading the book, and professionals and practitioners making organisational decisions concerning dependable human-computer systems, will also find it of value.
