“Refactoring (noun) : a change made to the internal structure of software to make it easier to understand and cheaper to modify without changing the observable behavior of the software.
To refactor (verb) : to restructure software by applying a series of refactorings without changing the observable behavior of the software.”

“Refactoring is a disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior. Its heart is a series of small behavior preserving transformations. Each transformation (called a 'refactoring') does little, but a sequence of transformations can produce a significant restructuring. Since each refactoring is small, it's less likely to go wrong. The system is also kept fully working after each small refactoring, reducing the chances that a system can get seriously broken during the restructuring.”

“The hardware of a computer is useless without the right software. Similarly, in an organization the hardware (strategy and structure) is inert without the software (beliefs and behaviors).”

“Economic principles underlie the overall structure of the software lifecycle, and its primary refinements of prototyping, incremental development, and advancemanship. The primary economic driver of the life-cycle structure is the significantly increasing cost of making a software change or fixing a software problem, as a function of the phase in which the change or fix is made.”

“If anything, there's a reverse Moore's Law observable in software: As processors become faster and memory becomes cheaper, software becomes correspondingly slower and more bloated, using up all available resources.”

“Software Engineering Economics is an invaluable guide to determining software costs, applying the fundamental concepts of microeconomics to software engineering, and utilizing economic analysis in software engineering decision making.”

“If you want to do something that's going to change the world, build software that people want to use instead of software that managers want to buy.”

“Executable UML is at the next higher layer of abstraction, abstracting away both specific programming languages and decisions about the organization of the software so that a specification built in Executable UML can be deployed in various software environments without change.”

“Software has to be designed by hackers who understand design, not designers who know a little about software. If you can't design software as well as implement it, don't start a startup.”
