Which of the following is an example of a domain asset?

A software component is an example of a domain asset because it represents a reusable and maintainable piece of software that can be part of a larger system or application. Domain assets encompass entities that can provide significant value in systems engineering, including components designed specifically for particular types of applications or environments.

In the context of systems engineering, domain assets are typically established within a particular domain where they can enhance the efficiency, functionality, and reliability of systems. The software component fits this definition as it can be integrated and utilized across various projects within its domain, providing a framework or set of functionalities beneficial for system development.

The other choices, while valuable in their contexts, do not serve as domain assets in the same manner. Mechanical parts and physical products in inventory may be specific to certain projects or manufacturing processes rather than broadly applicable across various systems. A single-use requirement statement is too transient and lacks the reusable characteristics that define a domain asset.
