About Enterprise Architecture:

Enterprise Architecture is an organization within the Chief Technology Office at

technologies that are leveraged by engineering teams across the enterprise.

2. Architecture as Design: this pillar includes the solution and technical

design for transformation programs and business critical projects which need

architectural guidance and support.

3. Governance: this pillar is responsible for defining technical standards, and

developing innovative tools that automate controls to ensure compliance.

4. Colleague Enablement: this pillar is focused on colleague development,

recognition, training, and enterprise outreach.
