1. A method comprising:

  • measuring performance characteristics of network components that are used to provide a customer service to an end customer, the customer service including one or more service instances that each use a different subset of the network components;

    generating trigger signals that include values representing the measured performance characteristics;

    selecting a mapping model from among multiple mapping models, the selected mapping model including at least first through third correlation functions;

    applying the first correlation function to the trigger signals to obtain a set of key quality parameters that measure a performance of each subset of the network components;

    applying the second correlation function to the set of key quality parameters to obtain a set of service quality parameters that measures a performance of each service instance;

    applying the third correlation function to the set of service quality parameters to obtain a customer quality parameter which reflects a service quality of the customer service as perceived by the end customer; and

    outputting an output signal that includes the customer quality parameter.
