The Pattern
Captions available
The idea
A pattern documents a recurring problem and provides a reusable template — a problem-solution pair within a context, plus the rationale binding the two and capturing proven experience.
In practice
A mapping team recognizing "we've solved this shape" and reaching for the write-up is patterns working.
Where people slip
The rationale is part of the pattern, not commentary.
