EA Program Development
Build an enterprise architecture function that earns its seat at the leadership table — from team structure and governance to tooling and a working practice.
Understanding This Service
What We Build
We design and stand up your enterprise architecture function from the ground up — or significantly restructure an existing one — covering team structure, governance, methodology, tooling, and the operating model needed to deliver value continuously.
TOGAF-Grounded Programme
The EA programme is designed around TOGAF Architecture Capability Framework principles, ensuring it is built on a solid, recognised foundation that can be sustained and scaled as your organisation grows.
Value from Day One
We structure the programme so early deliverables demonstrate value to the business quickly, building the credibility and stakeholder trust the EA function needs to become a permanent and influential part of your organisation.
Why Clients Request This Service
No enterprise architecture function exists
Existing EA team is not delivering recognised business value
Architecture governance is absent or inconsistently applied
IT investments proceed without architecture oversight
Scope of Testing
Our EA Program Development engagement covers:
Current State and Mandate Assessment
Review of current architecture capability, stakeholder expectations, business strategy context, and the mandate for the EA function within your organisation.
EA Function Design
Design of the EA team structure, roles, reporting lines, and interaction model with IT and business stakeholders.
Governance Framework
Design of architecture governance including decision rights, Architecture Review Board structure, standards management, and exception handling.
Methodology and Tooling
Selection and adoption of an appropriate EA methodology (TOGAF ADM adaptation) and architecture modelling tooling suited to your organisation's scale.
Operating Model and Enablement
Development of the EA operating model, initial architecture principles, and enablement of the EA team to operate independently after the engagement closes.

What Makes Our Testing Different
EA Program Development from Portamus builds the enterprise architecture function your organisation needs to govern IT investment decisions, enable digital transformation, and ensure technology strategy stays aligned to business objectives. Drawing on the TOGAF Architecture Capability Framework, we design and stand up the team structure, governance framework, methodology, and tooling — then enable your team to operate it independently. The result is a credible, value-delivering EA practice built to last well beyond the engagement that created it.
