A script, also called a discussion guide, is a list of tasks and follow-up questions a reseracher presents to participants in the interview portion of a usability study. The important of writing scripts is that it gives you a clear uderstanding of what a user is trying to do, how they think and feel, and what their problems are. Scripts writing will improve your ability to understand users and identify solutions that address their needs. The tasks and following questions should be based on the research questions and KPIs you chose earlier in the study plan.
A well-rounded script is:
- Open-ended: task and follow-up questions encourage discussion and reflection rather than short “yes or no” responses
- Objective: tasks and follow-up questions don’t try to lead participants toward a particular answer or introduce the researcher’s personal bias
- Goal oriented: tasks and follow-up questions relate directly to the research goal
In addition to your tasks and follow-up questions, a script should always include an introduction at the beginning. This will allow you to gather important demographic data, set a professional tone for the interview, and help your participant feel comfortable.
A good introduction will:
- Ask for the participant’s consent to record the interview
2. Inform the participant that the interview is not a test, and that no answer is wrong
3. Assure the participant that it’s okay to ask questions, and explain why their data is being collected
4. Ask for basic information that gives you insights into the participant’s relationship with the product and helps them settle into the interview
In the interview, you’ll be giving tasks to your participants and recording how they respond. Afterward, you’ll ask the participant follow-up questions to see what their experience was like. You’ll write a task prompt and follow-up question for each task you want your participants to complete. These will be based on the KPIs you chose earlier in your study plan. Here are a few tips when coming up with tasks for your usability study:
- Tasks should be based on your research goals
- Tasks should be specific
- Tasks should make participants take direct action
- Tasks shouldn’t provide clues on how to complete a task
Write your script
Write a script containing tasks and follow-up questions for participants. It should include:
- An introduction section
- Prompts for each task you’ll assign study participants
- Follow-up questions you’ll ask study participants

- I want you to know that this isn’t a test. There is no “right” anwser, and none of your responses will be considered wrong.
- If you have any questions, please don’t hesitate to ask.
