In usability testing, the facilitator is like the captain of the ship. Their job is to make sure everything runs smoothly during the testing session. A facilitator's responsibilities include:

• Setting up the testing environment
• Recruiting participants
• Explaining the tasks to participants
• Collecting data on the participants' performance
• Debriefing them at the end
• Analyzing the results to identify any issues or opportunities for improvement

Think of the facilitator as the go-to person who keeps everything on track and ensures that the testing session is a success.

Who can become a facilitator? Usually, it's someone who works in user experience, design, or product management and has a good understanding of the product and the target user group. They should have experience in conducting usability testing studies and be able to lead discussions and moderate the session.

Sometimes, companies might bring in a professional facilitator to make sure the testing is done properly. However, in smaller organizations or startups, someone on the team might take on the role of facilitator if they have the necessary skills and experience.
