IMO programs are 90% data or information, and modern software vastly underutilizes that concept.
If you know what data you need, who needs it, and where it needs to go, you have most of your system designed. If you just raw dog it then stuff is all over the place and you need hacks on hacks on hacks to perform business functions, and then you have spaghetti code. And no, I don't think domain modeling solves it. It often doesn't acknowledge the real system need but rather views the data in an obtuse way.
Per Fred Brooks: "Show me your flowcharts, but keep your tables hidden, and I shall continue to be mystified. Show me your tables, and I won't need to see your flowcharts; they'll be obvious."
It's telling that PRIDE incorporates the concept of Information Resource Management, or meticulous tracking and documentation of every piece of data used in a system, what it means, and how it relates to other data. The concept of a "data dictionary" comes from PRIDE.
