In this tutorial, we will discuss the ITIL Architecture Management Process (Also Known as ITIL Enterprise Architecture Management). In this chapter, you will learn the Definition, Objective, Roles, and Activities of Architecture Management - ITIL V3 Process.
What is ITIL Architecture Management Process?
Architecture Management process is NOT officially defined as a process in ITIL Service Design, and ITIL v3 official documentation doesn’t describe any detail about this process. But this process/framework is used throughout the ITIL lifecycle to maintain the standard technology architecture of an organization.
As described in the ITIL books, ITIL Architecture Management Process helps to verify that all deployed products and services operate according to defined Enterprise Architecture Baseline.
That is the reason, it is also called as ITIL Enterprise Architecture Management Process.
So, in view of the above context, we have decided to discuss this process to provide you some insight into it. We would not discuss the process in-depth but to provide you sufficient information required for the ITIL Foundation Examination purpose.
ITIL Architecture Management Objective:
The primary objective of ITIL Architecture Management process is to define & maintain a baseline for the future technological development, taking into account the organization's service strategy and newly available technologies.
ITIL Architecture Management Sub-Process:
In ITIL v3, no sub-processes are defined under this process.

Important Terminologies and Definitions:
Enterprise Architecture (EA):
- An Enterprise Architecture (EA) is a description of the essential components of a business, including their interrelationships.
- In ITIL, Enterprise Architecture mostly covers the following domains: Business, Information, Applications, and Technology.
- ITIL Architecture Management is considered to be a subset of the whole Enterprise Architecture Framework.
- Application Framework promotes the re-use of components (application modules) and helps standardize the technologies on which applications are based.
- Application Framework defines classes of applications, typically with common non-functional requirements. Therefore, it has to be planned and managed separately from software development projects, but it must also be aligned with the needs of software developers.
Change Request to Enterprise Architecture:
- A request to change or extend the Enterprise Architecture.
- Usually, it is issued from any of the Service Design process, when the introduction or modification of a service is not possible within the constraints of the existing architectural baseline.
ITIL Architecture Management Roles and Responsibilities:
- This role is the Process Owner of ITIL Architecture Management Process.
- The Enterprise Architect role is responsible for maintaining the Enterprise Architecture (EA).
- In Larger organizations, there may also be separate EA roles having special domain knowledge, such as Business Architect, Application Architect, Information Architect, or Infrastructure Architect.
