Poka-yoke is a design approach that prevents an error or makes it detectable when it occurs. It can be applied to objects, processes and interfaces
What it means, how it is used and where it comes up, with its related concepts.

In digital products, disabling a button without explaining why can create another difficulty. Prevention should make the task understandable and offer recovery, without blocking legitimate actions or concealing requirements.
