Aimed at determining the strategies behind these programs in a structured and comprehensive manner, methods of administration such as Balanced Scorecard (BSC) have been adopted. However, failures such as non-measurement of uncertainties involved up until the desired goals have been reached, suggest the adoption of more sophisticated formulae, such as Bayesian networks (BN) rather than BSC. In the case of BN, the challenge becomes a proper quantification of its parameters, allowing reliable estimates from them. The objective of this work is to evaluate the performance of BN in handling a given real PHR problem by means of the comparison between its predictions and the respective observed results. The model has been developed from a BSC and subsequently quantified according to expert opinions, since n...
