Matthew Deeprose created guidance for staff at the University of Southampton on using unsupported tools. He developed an overview document and criteria for assessing tools. The overview explains that staff should check if the university already has a similar supported tool before using others. It also covers issues like data privacy, sustainability, copyright and accessibility to consider. Matthew drafted criteria like tools must be free-to-use without time limits, not require personal information, and meet accessibility standards. He shared the overview with staff for feedback to refine the guidance.
