Government enterprise architecture
The Government Enterprise Architecture for New Zealand (GEA-NZ) is a common language and categorisation framework that promotes consistency in the way government models its business processes, services and infrastructure.
The Government Enterprise Architecture for New Zealand (GEA-NZ) guides our transformation towards coherent digital government. GEA-NZ includes:
- a layered architecture framework
- reference architectures
- toolkits and guidelines
- the GEA-NZ standards reference.
The cross-agency Government Enterprise Architecture Group (GEAG) helps the GEA team to develop GEA-NZ and oversee the architecture of all-of-government initiatives.
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 - standards reference
- defines sets of reference models and patterns - reference architecture
- defines and identifies government business capabilities - government business capability model.
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 all-of-government 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.
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 all-of-government programmes and services.
Digital technologies support some of the capabilities, but the enterprise architecture is not just about technology; it supports whole-business organisational change programmes.
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 GEA-NZ Standards Reference includes reference to standards and policies developed and owned by a number of government agencies and international bodies. It brings together standards used across of the New Zealand Government including, but not limited to:
- NZ specific ICT standards such as the NZ CIQ Profiles
- approved international standards for government agency use
- external standards collections that cover specific areas, for example web standards, data collection and representation.
The architecture resources page includes:
- Governance and maturity tools—to help measure and improve data and information governance and maturity.
- Information discovery process guidelines and template—this enables information to be discovered and structured consistent with the GEA-NZ Data and Information Reference Model and Taxonomy.
- Information asset catalogue template—Information asset catalogue(s) are intended to provide searchable metadata and contact details for a list of high-value information assets, held by the New Zealand Public sector.
