ABSTRACT
Components-Based Development (CBD) and Web Services (WS) nowadays are prominent
paradigms for implementing and deploying advanced distributed information systems. They
have been proposed as the ways to support effective business/IT alignment and produce high
quality and fl exible software solutions that fulfi ll business goals within short time-to-market.
However, current achievements in these areas at the level of methodology are much behind
the technology ones. CBD methods proposed so far lack a comprehensive support for com-
ponent and service concepts throughout the development process. By treating components
as packages of implementation artifacts during software deployment or as larger-grained
business objects during analysis and design, these methods are not well equipped for mod-
eling loosely coupled coarse-grained components that offer business meaningful services
organized in a Service-Oriented Architecture (SOA). This chapter presents an evaluation
framework that highlights the extent to which a particular method is component-based and
