GEA-NZ framework
The GEA-NZ framework provides an all-of-government (AoG) view of how the system architecture needs to support strategic goals, policies and investments.
The Government Enterprise Architecture for New Zealand (GEA-NZ) framework guides our transformation towards coherent digital government and includes a layered architecture framework.
The GEA-NZ framework is a toolkit to guide an organisation’s transition to working in a connected and digital world. It:
- provides a unifying common language
- categorises and describes shared product and services — common capabilities
- categorises and defines relevant standards and guidelines — digital standards catalogue
- defines sets of reference models and patterns — reference architecture
- defines and identifies government business capabilities — government business capability model.
Benefits
Enterprise architecture helps you:
- understand your current business
- identify opportunities for change
- model your business goals and the capabilities and investments you need to deliver them
- design a future operating model that is technically and strategically aligned with AoG programmes and services.
Detailed advice
At the more detailed agency and sector levels, the GEA-NZ framework offers:
- a ‘starter framework’ to help agencies that are redeveloping their enterprise architectures to align agency modelling to sector and AoG views
- an outline of the major components and relationships that agencies and sectors should model to maintain an efficient and effective ICT asset base and to support business transformation initiatives
- a set of reference models and patterns, focusing on common elements such as authentication and data interchange
- an ICT standards base.
