In this course, the focus will be on business modeling, systems modeling in general, and large-scale reusability. Business models are essential to understand the context of the systems that are part of an organization or to help with their integration. System modeling in general should take into account different types of systems and quality requirements that should be analyzed (and conflicts resolved) in order to obtain robust architectures. Finally, large-scale reusability techniques (e.g. in the context of software product lines) should be taken into account in order to increase productivity.

At the end of this curricular unit the student will have acquired knowledge, skills and competences that will allow him to model organizational processes such as context of software systems and also model-based development of software models. In particular, students should:

• Understandthe role of models in software development; BPM and SysML models; tools to support modeling; techniques for large-scale reuse modeling.
• Be able toeffectively use the above tools to specify software models.
• Knowthe concepts and techniques of modeling business processes and systems.
