Tesler’s Law
Tesler’s Law states that every system has a certain amount of complexity that cannot be eliminated. The goal is to shift this complexity from the user to the system or vice versa.

- Break Down Tasks: Divide complex processes into simple, manageable steps.
- Keep Improving: Regularly test your system to find and fix areas that confuse users.
Key Takeaway
In Summary
Tesler's Law encourages us to design systems that handle complexity internally, so users don't have to deal with it. This results in happier customers, fewer errors, and a system that can grow with your business needs.
Questions about Tesler’s Law
The process, first. Complexity removed from the process disappears; complexity removed from the interface usually moves to the user. If a step exists because of an internal constraint, fixing that constraint is worth more than any amount of visual tidying.
The system, wherever it has the information. If a value can be inferred, infer it. If you must ask, ask once and remember. The complexity that genuinely belongs to the user is the part only they can decide, and that part should be as clear as you can make it.
