Description
SWAT studies software systems: their design, construction and evolution. Our mission is to learn to understand software systems and to improve their quality. In particular, we study the causes of software complexity – a major cause of technology failure in society – and investigate how complex systems can be made simpler and more reliable. We analyze and visualize software systems, transforming them into better versions of themselves. We also generate new software with the goal of simplifying it through automation and abstraction. We keep our feet on the ground by working with corporate IT departments on streamlining their software systems and making them more reliable. Putting our ideas into practice is the best way to ensure they work.
