ISO 30004:2012 provides generic advice on the application of ISO 30000:2009.
It explains the underlying principles of ISO 30000 and describes the intent, typical inputs, processes and typical outputs, for each requirement of ISO 30000. This is to aid in the understanding and implementation of ISO 30000.
ISO 30004:2012 does not create additional requirements to those specified in ISO 30000, nor does it prescribe mandatory approaches to the implementation of ISO 30000.
