    (De la Salle Lipa Philipines + Universitas Widyatama Bandung, 2011-04-27) Murnawan; Sumiati, Ros
    To create such an integrated perspective of enterprise architecture, we need both a description technique for architectural models and model-based analysis techniques to realize this global optimization in practice. However, the value of architecture models increases significantly if they can also be used to support the decision making process. In this paper we argue that whenever a change in the enterprise architecture is needed, model-based analysis plays a central role.This paper presents an approach for quantitative analysis of layered, service-based enterprise architecture models, which consists of two phases a top-down propagation of workload parameters and a bottom-up propagation of performance or cost measures. By means of an example we demonstrate the application of the approach, and show that a seamless integration with other performance analysis methods.
