Overview

Define a set of principles for each of the six EA domains.
Principles are not exhaustive and can be extended with domain specialists.
Ensure standardisation, consistency, and alignment across components.

Principles Catalog by Domain

Business Architecture

Code	Principle	Rationale
BA 01	Strategic Alignment	Link business strategy to EA to deliver added value.
BA 02	Innovation and Creativity	Adopt innovation in investment decisions for emerging technology.
BA 03	Co-creation & Interoperability	Collaborative work between internal units and external stakeholders.
BA 04	Unified Documentation & Execution	Follow unified reference standards for documenting capabilities and services.
BA 05	Business Continuity	Ensure continuity of critical capabilities and services in all circumstances.
BA 06	Regulatory Compliance	Comply with all laws and policies when developing business architecture.

Beneficiary Experience Architecture

Code	Principle	Rationale
XA 01	Beneficiary Centricity	Align with DGA beneficiary-centric policy.
XA 02	Beneficiary Segmentation	Study all beneficiary segments and their needs.
XA 03	Life Experience	Achieve full coverage and integration in service delivery.

Application Architecture

Code	Principle	Rationale
AP 01	Fit for Purpose	Define application functions that fit business digitisation.
AP 02	Based on Standards	Build on global standards while complying with national policies.
AP 03	Ease of Use	Design easy-to-learn applications with multi-channel access.
AP 04	Secured by Design	Integrate security into the design of all components.
AP 05	Adaptable & Scalable	Accommodate changes in requirements and workload systematically.
AP 06	Reusable	Design modules to operate independently and be reusable.

Data Architecture

Code	Principle	Rationale
DA 01	Single Request for Data	Request data from beneficiaries once; integrate with sources.
DA 02	Single Data Source	Rely on a single trusted source per data entity.
DA 03	Data Governance Compliance	Comply with approved data management and governance standards.
DA 04	Support Analysis & Decision Making	Use data to support leadership in decision-making.
DA 05	360-Degree View	Full documentation of data entities and their relationships.

Technology Architecture

Code	Principle	Rationale
TA 01	Cloud First	Cloud computing as a core part of technology strategy.
TA 02	Compliance with Standards	Comply with national and global standards (NCA, ISO, NIST).
TA 03	Business Led Changes	Respond to business needs and plan changes accordingly.
TA 04	Control Technical Diversity	Reduce maintenance costs and unify technologies.
TA 05	Resilience & High Availability	Resilient infrastructure with redundancy and failover.
TA 06	Cost Optimization	Design for best cost use and efficiency.
TA 07	Scalability & Performance	Design scalable solutions with optimal performance.
TA 08	Environmental Sustainability	Consider sustainability and reduce carbon impact.

Security Architecture

Code	Principle	Rationale
SA 01	Least Privilege	Restrict permissions to the minimum required for the role.
SA 02	Defense in Depth	Apply multiple layers of security controls.
SA 03	Zero Trust Architecture	Security model based on "never trust, always verify".
SA 04	Strong Identity Foundation	Establish a unified IAM framework.

Compliance & Expected Outputs

Compliance status (compliant, non-compliant, partially compliant, not applicable, unknown) can be measured for technical specifications, workbooks, designs, and proposals.

Governance Note

Expected outputs include EA principle cards for all domains, linking principles to EA requirements per domain, and compliance status. These principles improve EA governance and achieve cost efficiency in investment decisions.
