Web services technology has become a key technology for system integration and the implementation of service-oriented architectures. However, many organizations are still facing challenges implementing Web services-based applications on a larger scale. The lack of an accepted and reliable framework for the implementation of Web services has been identified, among other issues, as one important challenge. The underlying assumption is that Web services-based implementations entail substantial changes in how applications are developed. The study presented in this paper examines the impact of Web services on the software development process. The current results of this research provide insights into the characteristics of software development based on Web services. The outcomes of this research are intended to contribute to a framework for guiding software methodology choices and adjustments in the context of Web services.
