It is becoming increasingly acceptable that thecomponent-based development is an effective, efficientand promising approach to develop distributed systems.With components as the building blcks, it is expected thatthe quality of the end system can be predicted based onthe qualities of components in the system. UniFrame isone such framework that facilitates a seamlessinteroperation of heterogeneous distributed softwarecomponents. As a part of UniFrame, a catalog of qualityof service (QoS) parameters has been created to providea standard method for quantifying the QoS of softwarecomponents. In this paper, an approach for compositionand decomposition of these QoS parameters is proposed.A case study from the financial domain is indicated tovalidate this model.
