Object-oriented design principles haven't had the effect we hoped for. The SOLID principles are excellent design guidelines, but experience shows that programmers find them difficult to follow. What do we do about this? Surprisingly, the Structured Design literature of forty years ago contains compelling solutions to many current design problems. They're simple and easy to understand, but were lost in the noise as OO rose to popularity. We'll reinterpret these simple design ideas in a modern context, finding that many of our most promising new design ideas resemble them. Rapid web application development, the area of professional programming in most dire need of design improvements, will serve as an example.
