The decisions you make while thinking about code are far too complicated to trust to memory. Ken shows how Understand helps you not rely on short term memory and walk code in an organized fashion that misses nothing.
If you want to make smarter, safer, and testable changes you need to know exactly where what you are changing will affect. Hyper-Xref technology, and the GUI and API/DevOps tools in Understand make you a safer, smarter engineer less likely to add bugs as you change code.
Using precise cross-references from static analysis tools like Understand tells you exactly where to look both for direct implications of what you are about to change and also, importantly, for subsequent impacts or side-effects of those changes
