The stage promotion process is intended to ensure technologies and services are sufficiently proven for the next stage and can be supported. It would be reasonable for a unit to demonstrate prior to a pilot deployment that an eventual full deployment is feasible, affordable and has likely value to the institution.
To have a standard process and guidelines for the evaluation of a solution at various stages, the framework uses standard categories of assessment between gates but different criteria in each category per gate.
The evaluation will involve standard IT Governance bodies and include subject matter experts where appropriate.
