AbstractInformation Technology (IT) is gaining more and more in importance in the business activities of our organizations, while causing some problems. Among others, the functionalities of information systems do not always meet the stakeholders’ needs. In many organizations, the exchange of information between the business level and the IT level often proves to be missing, unstructured or only achieved in the short term. This significant class of problems concerns the Business and IT Alignment. This is the research domain in which researchers try to provide solutions to bridge the business and the IT perspectives on the strategic, tactical and operational levels.
In this thesis, we propose several contributions which solve some of the business and IT alignment issues in service-oriented environments. To do so, we analyse and formalize the information exchanges between the business level and the IT level during the service-oriented requirements engineering process. We also study the alignment between the service-oriented computing life cycle and the IT service management life cycle. In this scope, two decision models are proposed. Based on a requirements model, the first one is able to rank several alternative solutions from a financial viewpoint. It helps requirements engineers and stakeholders to make a decision when there are conflicting and/or optional requirements. The second model can estimate the development effort needed when implementing services in a service-oriented architecture.
