Design Discovery In Existing Systems

We all want the best design but often that is not directly obtainable. Our tools for understanding systems behavior may lead us to the abstractions we would want to use in a rewrite but what about the abstractions that exist in the system now? Do they matter? What about the structure? Are there unnamed concepts we can see through the current cohesion and coupling in the system that will help us get to where we need to go? In this talk, Michael Feathers will describe cases where being aware of what currently exists leads to better solutions. We can often leverage what we have instead of building up a domain from a greenfield.
