Modern companies including telecommunication companies and mobile operators working in the global environment should guarantee technological effectiveness and innovation, renewing their technologies and services. Operation Support Sys-tem/Business Support System is used in telecommunication companies. In current state-of-the-art approaches, several itera-tions involving analysts and system architects are necessary, methodologies allow modeling non-functional or functional re-quirements but they do not take into account the interaction between functional and non-functional requirements as well as collaboration between services. Web Services Agreement is a convenient way to contain QoS parameters but state-of-the-art SLA-aware methods cannot support all classes of non-functional parameters and provide run-time support and dynamic recon-figuration at the same time. The approach proposed in this paper fills this gap. It employs a well-defined workflow and analy-sis model for developing and adapting complex software systems including support of all classes of non-functional parameters and providing run-time support and dynamic reconfiguration of provided services.
