Method for adjusting values of parameters for a virtual sub-set of a network, called the "network slice " in an initial operating state, said network slice in an initial state being dedicated to a service, the method comprising animating a graphical interface in which polar coordinates are associated with each of the parameters of the network slice in the initial state, with an angular coordinate being assigned to a parameter and a radial coordinate being assigned to the value of this parameter, the method comprising at least the following steps: - acquiring a plurality of input parameter values for a network slice, the input parameters defining the service provided by the network slice in the initial operating state; - distributing on the graphical interface the input parameter values with association to each of the input parameters of an angular coordinate dedicated to this input parameter and a radial coordinate, which is an increasing function of the value of this input parameter, so as to form a first visual fingerprint; and - on change of a value of at least a first input parameter, and with that, on change of the radial coordinate associated with the first input parameter: estimating, based on predetermined rules, values of one or more second input parameters depending on the changed value of the first input parameter, changing radial coordinates respectively associated with the values of the one or more second parameters on the graphical interface, depending on the estimated values of the one or more second input parameters so as to form a second visual fingerprint superposed on the first visual fingerprint, and applying the changed value of the first input parameter and the estimated values of the one or more second input parameters as output parameter values of the network slice, the output parameters defining the service provided by the network slice in a final operating state, wherein the change of the value of the first input parameter is carried out by means of a human-machine interface. - acquiring a plurality of input parameter values for a network slice, the input parameters defining the service provided by the network slice in the initial operating state; - distributing on the graphical interface the input parameter values with association to each of the input parameters of an angular coordinate dedicated to this input parameter and a radial coordinate, which is an increasing function of the value of this input parameter, so as to form a first visual fingerprint; and - on change of a value of at least a first input parameter, and with that, on change of the radial coordinate associated with the first input parameter: estimating, based on predetermined rules, values of one or more second input parameters depending on the changed value of the first input parameter, changing radial coordinates respectively associated with the values of the one or more second parameters on the graphical interface, depending on the estimated values of the one or more second input parameters so as to form a second visual fingerprint superposed on the first visual fingerprint, and applying the changed value of the first input parameter and the estimated values of the one or more second input parameters as output parameter values of the network slice, the output parameters defining the service provided by the network slice in a final operating state, wherein the change of the value of the first input parameter is carried out by means of a human-machine interface. estimating, based on predetermined rules, values of one or more second input parameters depending on the changed value of the first input parameter, changing radial coordinates respectively associated with the values of the one or more second parameters on the graphical interface, depending on the estimated values of the one or more second input parameters so as to form a second visual fingerprint superposed on the first visual fingerprint, and applying the changed value of the first input parameter and the estimated values of the one or more second input parameters as output parameter values of the network slice, the output parameters defining the service provided by the network slice in a final operating state, wherein the change of the value of the first input parameter is carried out by means of a human-machine interface.
