Four usability testing mistakes to avoid

Listicle of four usability testing mistakes: testing the what without the why, leading participants, stopping at one round and leaving insights in recordings.
Check your next study plan against these four before you book sessions.

Four common mistakes that waste usability studies. Task pass rates without follow-up questions miss the reasons behind failures. Leading prompts inflate success rates. One round of testing misses the new flows each fix creates, even though about five users find most issues in a single design. And session recordings nobody watches never turn into decisions. Koji can add the interview step and code the themes for you.

Where this appears

What's in this guide

  1. Testing the what without the why: Pass and fail rates show where users struggle. Pair them with a few interviews to learn why.
  2. Leading the participant: Prompts that hint at the right path inflate success rates. Keep the guide neutral.
  3. Stopping at one round: Five users find about 85% of issues in one design. Each fix adds new flows to retest.
  4. Letting insights die in recordings: Videos nobody watches are not research. Code the themes so sessions turn into decisions.
