After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standard as anAustralian Standard rather thanan Australian/New Zealand Standard. The objective of this Standard is to establish a set of process descriptions for the governance and management of a collection of architectures and the architecting of entities. This document also establishes an enablement process description that provides support to these other architectureprocesses.
