A usability report is a document that summarizes the findings of a usability testing session. It typically includes information on the goals of the testing, the methods used, the participants, and the results and recommendations.  A usability report should include a summary of the key findings of the testing, including any problems or issues that were identified and the impact they had on the user's ability to complete tasks. It should also include recommendations for improving the usability of the product or service based on the findings of the testing.  In addition to the summary of findings, a usability report should also include detailed information on the testing methods used, the participants, and the tasks they completed. This information can help stakeholders understand the context and significance of the findings and recommendations.
