Aplicação da técnica Delphi para validação dos métodos a serem utilizados no sistema em plataforma web para implantação de Plano de Segurança da Água

Abstract

This work aims to validate the methods to be used in the Web platform system, aiming at the implementation of the Water Safety Plan, in accordance with the guidelines of the World Health Organization and the Ministry of Health, through the use of the Delphi technique. In order to do so, the most used methods in the countries were selected, such as: Hazard Analysis and Critical Control Points (HACCP) and the Risk Prioritization Matrix. The validation was carried out through the aid of a questionnaire with four summary questions about the two methods with spaces for comments of the experts' opinions. The results of the validation of the methods occurred in two workshops (Brasília-DF and Campinas-SP) for face-to-face work and the suggestions were evaluated and discussed incorporated after consensus of all specialists. From the validation, the experts concluded by using only the risk prioritization matrix with change and suggesting that the decision tree of the HACCP system needs adjustments. The validated matrix will reduce uncertainties and improve the efficiency of risk assessment.
