An implementation protocol ("Protocol") is a document constituting a formal agreement between Parties. It also represents a code of conduct for the Parties to the Protocol. An implementation protocol is sometimes also referred to as a memorandum of understanding.

A Protocol aims to promote good conduct, integration, participation, co-operation and co-ordination between Parties and includes, but is not limited, to aspects such as policy development and implementation, the exercise of statutory powers, the performance of a statutory function, the development and provision of a service or product, the implementation of a government programme, or managing a joint programme or project. Without digressing from the requirements set out in the IGR Act or the Framework and to broaden the scope of application for practical reasons, the general purpose of a Protocol is - To conclude an agreement between organs of state within or between spheres of government regarding any matter to achieve a government objective.

Any organ of state may initiate the process for the conclusion of an implementation protocol after consultation with other affected organs of state (Section 35(5) of the IGR Act).
