Case for support template

We have put together a skeleton case for support template seting out the key information that should be included in a case for support, e.g.

  • Justification of resources
  • Linkage to other ExCALIBUR projects
  • Description and costs
  • Work packages
  • Milestones and outputs
  • Risk register

A Frequently Asked Questions document is available which describes the ExCALIBUR H&ES open call process and provides guidance on scope and eligibility for projects. We have also produced a short video which walks you through what is required in an ExCALIBUR H&ES case for support:
