    Enterprise Architecture Involvement Overview
Enterprise Architecture Involvement Matrix

What does the involvement matrix for Enterprise architecture look like? Who interacts with enterprise architecture, what different roles does Enterprise Architecture perform? In general the EA roles should be evaluated according to the complexity of the architecture, size of the company and other factors in order to efficiently determine the relationship between the roles assigned to employees. In large corporations with complex business processes, an individual can be responsible for one specific role. In smaller companies, an individual can be responsible for several EA roles.

We will explain the involvement matrix across different departments, committees and other responsibilities. This include both the different roles that Enterprise Architects perform but also the different stakeholders and their involvement.
Usually we also touch on how this impacts enterprise architecture software. Most enterprise architecture tools will only support core enterprise architecture activities and will not go beyond that.

Company Head
Establishes Enterprise Architecture as a priority and issues policies for the development, implementation, and maintenance of the Enterprise Architecture.

Capital Investment Council
Composed of business unit heads, budget official, procurement official, legal counsel, CIO and CFO. Checks all proposed investment in the IT, chooses projects, makes the final investment decision and evaluates results for decisions related to project funding.

Chief Architect
Chooses the EA team and works with CIO to create architecture policy. Oversees EA development, implementation, and refinement. Responsible for architecture plan and reports directly to the CIO.

Chief Information Officer (CIO)
Provides directions to Enterprise Architecture Executive Steering Committee, appoints a Chief Architect, presents the EA benefits to other company executives and stakeholders. (Read about how to please stakeholders)

Configuration Control Board
It consists of Chief Architect and domain owners. Responsible for overseeing and control of the changes made to EA after initial implementation.

Domain Owners

Enterprise Architecture Executive Steering Committee

Enterprise Architecture Core Team

- Security Architect

Responsible for development and implementation of EA. Develops standard requirements and manages the architecture related processes. Works on maintaining the progress and establishing the high-quality architecture framework. It measures the architecture's effect on projects through process measurements.
Usually activities directly related to the core team are well support by enterprise architecture software offerings.

Subject Matter Experts
The company's experts and outside consultants in charge of documenting the business requirements and supporting the Chief Architect and EA staff.

Technical Review Committee
Involves Chief Architect, Senior Architectural Consultants, Domain Owners and Technical representatives. Responsible for business alignment, technical compliance and solution proposals. Also evaluates EA compliance and conducts regular reviews.
Within enterprise architecture tools this area seems to be more traction and is often considered part of enterprise architecture governance.

Hope this was helpful. Please note that the exact title of these departments and roles vary from company to company. And as Enterprise Architecture proves itself as a valuable organizational and structuring tool, companies are starting to recognize the practical use of architecture management. Today’s Enterprise Architecture tools will only offer support for key architecture activities directly related to architecture roles and will not go beyond that.
