Essential System Requirements: A Practical Guide To Event-driven Methods (addison-wesley Information Technology Series)

This book is the first step-by-step guide to introducing event-driven software development approaches proven to help IT organizations gain control over even the most complex systems. Event-driven software development divides the software system into highly cohesive, highly-independent "partitions" based on business events. This book helps developers, analysts and architects understand the strategy, in-depth, so they can use it to accelerate analysis. Readers will learn how to understand systems from multiple viewpoints, reflect user requirements more effectively, and model systems through a selective, iterative, and parallel approach that promotes easy prototying and early, low-cost error repair. Coverage includes: an insightful discussion of the nature of business events and their impact of the development lifecycle; specific event-driven methods and techniques for analyzing, specifying, and modeling information systems; a close look at function-point estimating; and techniques for partitioning responses to business events across object classes. To illustrate the book's key techniques, a detailed case study is presented. For anyone responsible for effective software development, including software engineers, system analysts, project managers, and other IT decision-makers.
