Broken Windows Theory

Wilson and Kelling's theory that visible signs of disorder (broken windows, graffiti, litter) signal that an environment is unmonitored and norms are unenforced, which invites further disorder and escalation. One broken window → more broken windows → vandalism → serious crime. In organizations: one tolerated quality failure signals that standards are optional, inviting broader quality decline. One unchallenged ethical lapse signals that ethics are aspirational, inviting larger lapses. The theory's core insight: environmental signals of norm enforcement (or lack thereof) shape behavior more powerfully than stated rules or personal character.

When to use it

When quality, culture, or standards are gradually declining; when small violations are being tolerated in hopes of addressing 'bigger issues'; when environmental design could reinforce norms more effectively than rules; when organizational entropy is producing a slow drift from standards.

How it can help

Maintain visible standards aggressively—especially the small, visible ones. Fix the broken windows immediately: small quality failures, minor process violations, and trivial environmental degradation all signal that standards are optional. In product development: treat minor bugs with the same seriousness as major ones, because tolerance of small defects signals tolerance of defects in general. In culture: address small behavioral violations early rather than waiting for big ones, because the small violations ARE the big ones—they're the environmental signal that norms aren't enforced.
