What type of requirement specifies what a product's components must achieve with measurable metrics?

The correct answer addresses performance requirements, which are crucial in the design and construction industry. Performance requirements focus on the measurable outcomes that a product or system must achieve. This includes specific metrics such as strength, durability, efficiency, and other quantifiable benchmarks that can be tested and verified. Establishing these measurable metrics allows stakeholders to clearly understand the expected performance levels, ensuring that the finished product meets the desired quality and functional standards.

In contrast, prescriptive requirements outline specific methods or practices that must be followed during construction, which doesn't necessarily focus on measurable performance outcomes. Design requirements typically detail the characteristics of the project without prescribing specific performance metrics, and functional requirements define what a product should do without necessarily stating how well it should perform those functions. Understanding the distinction makes it clear why performance requirements are vital when setting expectations for functionality and quality in construction projects.
