Classification of quality attributes for predictability in component-based systems

One of the main objectives of developing component-based software systems is to enable integration of components which are perceived as black boxes. While the construction part of the integration using component interfaces is a standard part of all component models, the prediction of the quality attributes of the component compositions is not fully developed. This decreases significantly the value of the component-based approach to building dependable systems. This paper classifies different types of relations between the quality attributes of components and those of their compositions. The types of relations are classified according to the possibility of predicting the attributes of compositions from the attributes of the components and according to the impacts of other factors such as system environment or software architecture. Such a classification can indicate the efforts which would be required to predict the system attributes that are essential for system dependability and in this way, the feasibility of the component-based approach in developing dependable systems.
