The difference between quality and reliability is that quality shows how well an object performs its proper function, while reliability shows how well this object maintains its original level of quality over time, through various conditions. Durability testing is generally considered a subset of reliability testing. Now this is a very complex thing to explain as most of the things overlap in their explanation.

The smaller the difference between the two sets of results, the higher the test-retest reliability. A more contemporary perspective sees this differently and with two key, separate, measurements: availability and durability. Machine availability measures total uptime divided by total downtime to get the percentage of available functional hours. With proper care, cars, trucks, and SUVs can last for well over 200,000 miles. And just, yeah, third example, EC2 has a little bit less availability than S3. Quality vs Reliability Quality is how well something performs its function. Reliability, though, is essentially the opposite of failure, HBR explains. Classic reliability testing is primarily concerned with measuring outright failure, such as time to failure, mean time between failures, number of failures per “n” units or operations, etc. Durability, then, is how well and how long a vehicle lasts. Simply put availability is a measure of the % of time the equipment is in an operable state while reliability is a measure of how long the item performs its intended function.
