What characterizes a performance (open) specification?

It states specific materials and brands
It allows for brand substitutions based on manufacturer's discretion
It demands detailed descriptions of requirements without trade names
It focuses primarily on warranty details

The correct answer is: It demands detailed descriptions of requirements without trade names

A performance (open) specification is characterized by its focus on detailing the functional requirements and desired performance outcomes of a product or system without specifying particular brands or trade names. This approach encourages innovation and allows manufacturers to propose various solutions that satisfy the specified criteria. By emphasizing performance rather than specific materials or brands, it provides flexibility in sourcing, as long as the alternatives can meet the stated performance standards. The approach taken in option C enables designers and clients to evaluate a range of potential products, making it easier to adapt to changing market availability and advancements in technology. This is particularly important in fields where products might evolve quickly, and being tied to specific brands can limit options and potentially hinder project outcomes.
