The implementation plan will, by necessity, need to be flexible over the coming years – both because lessons will be learned as implementation gets underway and because the technology and standards on which it will rely will continue to evolve at a rapid rate in ways that are impossible to anticipate today.

Clear and consistent communications will be required to continuously build awareness, understanding and adoption not just with service developers, but also with the individuals and businesses that will benefit.
