The field of software development often encounters many kinds of risks with high failure rate which in turn influence the success of software project. Success of software development associated with the effective management of risks occurred or might occur to mitigating the failure rate. This paper focuses on the life cycle of software development and the risks associated with each phase. It proposes a new model that helps in assessing and managing the risks and the processes needed in each phase of the development life cycle. The model is intended to unveil risks associated with each phase giving the opportunity to revisit phases in case of discovering associated risks as the development proceeds.
Web services are loose-coupled, which allows developers to create, generate and compose them at runtime. But, single Web service isn't sufficient to achieve most of user demand in the current period. Therefore, composition of Web services is the appropriate solution and it's the best way to deal with various user requests. It has received a great attention from different communities. A number of different standards/specifications have been proposed to tackle this issue. These standards are Ontology Web Language, Web Service Modeling Ontology, Business Process Modeling Language, Web Services Business Process Execution Language, Web Service Choreography Interface and Web Service -Choreography Description Language. In this paper, we provide an overview of different applications that have been developed based on each of these standards, and present three comparisons between those applications along with the popularity of Web search for them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
