What are primary dimensions of quality?

The primary dimensions of quality typically include performance, reliability, durability, and serviceability. Performance refers to how well a product or service meets its intended purpose, while reliability indicates the consistency of that performance over time. Durability measures the lifespan of a product under normal usage conditions, and serviceability relates to how easily a product can be repaired or maintained. Together, these dimensions help define the overall quality and customer satisfaction associated with a product or service.
