Overview

In our increasingly computer-aided environment, the performance of an expanding range of individual tasks, the operation of various critical procedures, and the viability of different organizations rely on the accurate function of software systems. But traditional strategies utilized to assess software reliability do not measure the significance of software failure, limiting their use and capability. Susan Sherer addresses limitations of reliability measures and verification technology, as well as constraints on software development, and introduces the concept of software failure risk measurement to devise, test, apply, and maintain a risk-controlled software system. Her well-grounded and cogent presentation begins with a framework for understanding software failure risk and risk measurement. New techniques to analyze risk in complex engineered systems, and the components of risk in software development, are described. The author proceeds to elucidate the principles of software failure risk assessment, and presents case studies involving a commercial loan system, a funds-transfer security system, and a payables processing system to illustrate the application of this novel methodology. The text concludes with discussions on the implications of the methodology on software development and use, and toward enhanced system management. Important guidelines for the acquisition and appropriate implementation of purchased software in order to minimize software failure risk are also featured. Software Failure Risk is a thorough study that provides a valid foundation for the design and operation of individual software modules, and enables users to critically assess competing software products for their specific requirements.
