“Modeling Principle: Models are not right or wrong; they are more or less useful.”

“Any fool can write code that a computer can understand. Good programmers write code that humans can understand.”

“Comprehensiveness is the enemy of comprehensibility”

“It is commonly said that a pattern, however it is written, has four essential parts: a statement of the context where the pattern is useful, the problem that the pattern addresses, the forces that play in forming a solution, and the solution that resolves those forces. … it supports the definition of a pattern as "a solution to a problem in a context", a definition that fixes the bounds of the pattern to a single problem-solution pair”

“People also underestimate the time they spend debugging. They underestimate how much time they can spend chasing a long bug. With testing, I know straight away when I added a bug. That lets me fix the bug immediately before it can crawl off and hide. There are few things more frustrating or time-wasting than debugging. Wouldn't it be a hell of a lot quicker if we just didn't create the bugs in the first place?”

“Graphical design notations have been with us for a while... their primary value is in communication and understanding. A good diagram can often help communicate ideas about design, particularly when you want to avoid a lot of details. Diagrams can also help you understand either a software system or a business process. As part of a team trying to figure out something, diagrams both help to understand and communicate that understanding throughout a team. Although they aren't, at least yet, a replacement for textual programming languages, they are a helpful assistant... Of these graphical notations, the UML's importance comes from its wide use and standardization within the OO development community.”
