What do you mean by certain quality? I mean, let's say, Apple has one quality standard, Xiaomi has another - do you evaluate the necessary service level that should be met for every company individually? Or a company sets the quality standard on its own and when this level is not met, customer gets compensated? Sorry for asking, just want to get deeper, cause idea itself looks pretty interesting and promising
For online services, Quality of Service (QoS) generally refers to the amount of time a service will be available to its users, called "uptime"
