Which heuristic is violated when a system uses jargon and technical language that the target users do not understand?

Accepted Answer

Match between system and real world

Answer

Match between system and real world requires that the system use words, phrases, and concepts familiar to the user, not internal system terminology.

Question 5

What distinguishes a heuristic evaluation from a cognitive walkthrough?

Cognitive walkthrough focuses on learnability for new users step-by-step
