Before revision:  A scheme for the estimation of some parameters of the model is illustrated, so that it can be tailored on the URLanizational structure of a specific bank . We focus on the case in which there are no causal loops in the matrix of couplings and exploit the exact solution to estimate also the parameters of the noise.
After revision:  A scheme for the estimation of some parameters of the model is illustrated, so that it can be tailored on the URLanizational structure of a specific bank by estimating some of its parameters from historical operational losses. The model is exactly solved in the case in which there are no causal loops in the matrix of couplings and exploit the exact solution to estimate also the parameters of the noise.
