A Method for Formulating and Architecting Component- and Service-Oriented Systems

Abstract

This chapter describes a negotiation-driven method that can be used to formulate and design component and service-oriented systems. Component and service-oriented development are increasingly being promoted in literature as rapid low-cost strategies for implementing adaptable and extensible software systems. In reality, these development strategies carry significant risk throughout the system life cycle. The risks are related to the difficulty in mapping requirements to component and service-based architectures, the black-box software used to compose the systems, and the difficulty in managing and evolving the resulting systems. These problems underscore the need for software engineering methods that can balance aspects of requirements with business concerns and the architectural assumptions and capabilities embodied in software components and services.
