Final answer:
In software engineering, design metrics can be used in test planning.
Step-by-step explanation:
The statement is True. In software engineering, metrics are used to measure and evaluate various aspects of a model or system. Design metrics, which evaluate the quality and effectiveness of a design, can be used in test planning to determine the necessary tests to ensure the design meets requirements and performs acceptably. For example, if a design metric shows that a design has a high complexity, more intensive and specific testing may be required to address potential issues or vulnerabilities.
