  • The supervisor (company or organization) would need access to usage and download information of end users -- who accessed what, how often and which materials or content were downloaded, etc.
  • The supervisor would have functionality for rolling out a user survey within the platform for end users to share feedback about their experience on the platform and/or how the materials and content have been useful to them.
  • The platform is optimized for low bandwidth areas where internet connections may be unstable and the user experience and interface has to be simple in order for it to be accessible to end users who may not be highly digitally literate.
