Volvo's enterprise architecture is designed to support the company's business operations and strategy by providing a framework for the organization's technology infrastructure and business processes. The enterprise architecture includes several layers, including business architecture, application architecture, data architecture, and technology architecture.

1. Business Architecture: The business architecture layer defines the business processes and functions within Volvo, including the organization's mission, vision, and goals. This layer includes business process models, organizational charts, and job descriptions.

2. Application Architecture: The application architecture layer defines the software applications that are used by Volvo to support its business processes. This layer includes application portfolios, application models, and system specifications.

3. Data Architecture: The data architecture layer defines the data entities and data flows within Volvo, including the organization's data models, data standards, and data governance policies.

4. Technology Architecture: The technology architecture layer defines the hardware and software infrastructure used by Volvo to support its business processes. This layer includes server specifications, network infrastructure, security policies, and technical standards.

To support these layers, Volvo has a centralized Enterprise Architecture (EA) function that works closely with business leaders and IT teams to ensure that the company's technology infrastructure aligns with its business goals and objectives. The EA team also ensures that the company's technology investments are optimized and aligned with its strategic priorities. Additionally, the EA team is responsible for providing guidance and standards for the development, implementation, and maintenance of technology solutions across the company.
