Clean Architecture: A Craftsman's Guide to Software Structure and Design

by Robert C. Martin

Modern developers are in a similar race, and exhibit a similar overconfidence. Oh, they don’t sleep—far from it. Most modern developers work their butts off. But a part of their brain does sleep—the part that knows that good, clean, well-designed code matters.

Therefore architectures should be as shape agnostic are practical.

The problem that Dijkstra recognized, early on, was that programming is hard, and that programmers don’t do it very well. A program of any complexity contains too many details for a human brain to manage without help. Overlooking just one small detail results in programs that may seem to work, but fail in surprising ways.

At every level, from the smallest function to the largest component, software is like a science and, therefore, is driven by falsifiability. Software architects strive to define modules, components, and services that are easily falsifiable (testable). To do so, they employ restrictive disciplines similar to structured programming, albeit at a much higher level.
