Final answer:
The critical success objective that requires the manufacturer to perform satisfactorily over a defined amount of time under specified conditions is reliability.
Step-by-step explanation:
The critical success objective that requires a manufacturer to perform satisfactorily over a defined amount of time under specified conditions is known as reliability. Reliability is a crucial aspect of product quality and refers to the ability of a product to consistently function as intended, without failure, over a given period. Manufacturers must ensure that their products meet the specified reliability requirements to build trust with customers and avoid any potential safety or performance issues.
For instance, let's consider a car manufacturer. If they claim that their car can run smoothly for 100,000 miles without any major breakdowns, they need to demonstrate that the car can indeed achieve this performance under specified conditions such as proper maintenance, normal driving conditions, and recommended usage.
