  • The Supplier will need to write a Summary in the box provided and attach a Functional Specification against the new version.

Why is a Functional Specification required by RDG?

  • A Functional Specification of the system must be provided to RDG Accreditation, to allow the accreditable functions to be identified.

    Where a function is deemed to be accreditable, but is not supported by existing RDG ticketing standards, the system will be referred to RDG’s Customer Proposition Committee for consideration.

    Based on the content of the Functional Specification, RDG Accreditation will provide an estimate of the accreditation effort involved and commence arrangements for the scheduling of an accreditation slot.
