patterns

From The Nature and Art of Workmanship
No two leaves of the same tree are precisely alike, each is individual: yet every one of them conforms to a recognizable pattern characteristic of the species.

From The Unknown Craftsman
If the material is poor the pattern will suffer.

From Quality Software Management. Vol 1. Systems Thinking
A culture is a self-sustaining pattern that has remarkable powers of resistance to change.

The essence of a pattern is what it can do consistently.

From Quality Software Management: Vol 1. Systems Thinking
A locked-on system tends to hold itself to an existing pattern, even against logical reasons to change. … Lock-ons occur in clusters.

The quickest and surest way to classify organisations into similar patterns is by the way people think and communicate.

From The Silent Language
A pattern is only meaningful if analyzed on its own level.

From Leverage Points
Self-organization is basically the combination of an evolutionary raw material - a highly variable stock of information from which to select possible patterns - and a means for experimentation, for selecting and testing new patterns.

From Patterns of Software
In most types of abstraction the common pattern is replaced by a name, such as a function name, a macro name, a class name...
