Web Services Software Development Methodology

Complex software systems involve the integration of many software components some of which may be legacy code. Automatic code generation tools and Computer-Aided Software Engineering (CASE) tools further complicate the problem by generating code thatinvolves tight interleaving between the various components. The result is unpredictable interdependencies between these components which complicates testing. We need a methodology that will enable components to function as loosely-coupled entities withwell-defined (and unchanging) interfaces. In other words, the dependencies should be at the interface level and the component interactions should be oblivious to changes in the internals of the components. We also need to
