Final answer:
The four facets of Enterprise Architecture are Business Architecture, Data Architecture, Application Architecture, and Technology Architecture. These facets help define and align the physical components of a product with its functional requirements, addressing various aspects of engineering challenges.
Step-by-step explanation:
The four facets of Enterprise Architecture are typically represented as different domains that make up the total enterprise structure. These domains are often classified as:
- Business Architecture - This facet involves the design of business strategy, governance, organization, and key business processes.
- Data Architecture - This refers to the structure of an organization's logical and physical data assets and data management resources.
- Application Architecture - This defines the blueprint for the individual application systems to be deployed, their interactions, and their relationships to the core business processes of the organization.
- Technology Architecture - This involves the hardware, software, and network infrastructure needed to support the deployment of core, mission-critical applications.
These facets of architecture help in addressing large-scale problems in engineering by focusing on various aspects such as the scientific, ethical, economic, and legal aspects, as mentioned in the provided reference. Furthermore, they contribute to evaluating the quality of a design by ensuring the physical building blocks of the product align with its functional elements, a principle highlighted by Eppinger and Ulrich (2003).
