What is a usability test script designed to do?

A usability test script is a critical component of conducting effective usability tests, as it serves the purpose of providing a structured format to track tasks and questions during the testing process. This script ensures that all participants are evaluated under the same conditions, allowing for consistent data collection across different sessions. By guiding the facilitator on which tasks to present and what questions to ask, the script helps facilitate a smooth testing experience, enabling the collection of qualitative and quantitative data.

Using a well-prepared script not only aids in maintaining focus during the session but also ensures that important criteria and objectives are addressed. As testers navigate through the tasks, the script allows for quick reference to ensure that no crucial aspect of the usability test is overlooked. This systematic approach fosters better comparisons of participant performance and leads to more reliable insights regarding usability and user experience.

The other choices, while related to broader aspects of user research and project management, do not specifically align with the unique purpose of a usability test script. They include concepts like methodologies, etiquette, and project milestones, which are not the primary focus while conducting usability tests. The essence of a usability test script is its ability to streamline the testing process by effectively guiding the facilitator through the necessary tasks and inquiries.
