This chapter summarizes the CoBRA application in the context of Siemens Information Systems, Ltd, India (SISL). In this chapter, we will present how to adapt the baseline CoBRA model development process to the needs and constraints of a particular organization in the embedded software systems domain. Moreover, we report on experience regarding the development of the CoBRA model throughout multiple refinement iterations. In particular, we will show how to analyze the performance of the CoBRA model, where to look for potential causes of observed deficits of the model, and how to appropriately improve the model. Finally, the SISL context shows how important the appropriateness and quality of the data used for estimation are for the successful estimation. We will provide examples of common deficits of measurement data and simple ways to identify and solve these deficits. In particular, we demonstrate how to define an appropriate size measurement approach for enhancement projects.
