The conversation between human and AI assistant.
Which requirement are the foundation from which quality is measured?
That makes sense. Can you give me an example of a product that excels in all of these requirements?
One example that comes to mind is the Tesla Model S. It has excellent functionality with its advanced autopilot system and electric motor, it is highly reliable with its low maintenance electric powertrain, it is highly usable with its large touchscreen interface and intuitive controls, it is highly efficient with its aerodynamic design and electric powertrain, it is highly maintainable with its over-the-air software updates, and it is highly portable with access to Tesla's Supercharger network.
