Software is not only difficult to create, but it is also difficult to understand. We explore the ways of preserving the comprehensibility of the intent with which software has been developed and how to achieve this directly in the corresponding code and model artifacts. Part of the solution to this problem lies in establishing and maintaining appropriate modularization. We focus on use case driven modularization and advanced (aspect-oriented) modularization. From the perspective of software quality, we explore using refactoring, automated testing, continuous revisions, and visualization of software properties. We also explore applying software development techniques beyond software development, in particular in education.
