Every system has inherent complexity that must be managed.

Tesler’s Law
Every system has inherent complexity that must be managed.

HOW IT WORKS: Complexity can be offloaded to the system to simplify user interaction. Users interact with a cleaner interface while the system handles underlying calculations, processes, or logic.


IN UX/UI/AI DESIGN: UX, UI, and AIX designers streamline front-end interfaces and let AI manage complex back-end tasks. Automation can handle repetitive or difficult operations while keeping users in control.


EXAMPLE: Spreadsheet software automates formula calculations while users see only results. A GenAI assistant performs data cleaning behind the scenes, presenting users with simplified outputs.

Tesler’s Law, introduced by Larry Tesler in the 1980s, observes that some complexity in systems is unavoidable, and designers must decide where it should reside: hidden from users or exposed for control.
