Who is responsible for Enterprise Architecture?

Enterprise Architecture is normally led by an Enterprise Architecture function, Chief Architect or similar leadership role.

However, architecture should not be considered the responsibility of architects alone.

Business leaders own business outcomes. Product owners understand customer and product needs. Security teams own security expertise. Data teams understand information requirements. Engineers understand implementation realities.

Enterprise Architecture brings these perspectives together.

Successful EA therefore depends on shared ownership and collaboration.

The architecture team should provide direction and expertise while ensuring that decisions remain connected to the people responsible for delivering and operating the organisation.
