Development of a Model with Critical Factors of Success, Predominant in Implementation of a Membrane System in the Wastewater Treatment—Review of the Case Study of a Dairy Industry

The objective of this study was to identify the critical success factors (CSFs) that predict, in a specific niche, the dairy sector in Brazil and later monitor their behaviors behavior when applied together with the project management activity, along with a case study where the extrapolation of the implementation of wastewater treatment by the combined membrane system was carried out. In order to develop the case, the hypothetical-deductive method was adopted and later the content analysis was carried out through the Sphinx Lexical (qualitative analysis) computer system, data clusters and quantitative data validation was performed with SPSS Statistic, allowing to understand CSF of classification. In applying this methodology, after grouping factors in the company, one can verify the existence of implicit relationships of the FCSs, impacting mainly on the organizational aspects, especially related to the effective communication and the need for managerial support in the decision making as the most representative and factors related to risk planning and analysis. As for the explicit impact of the factors with the organization, one can verify the predominance of cost factors, and the possibility of reusing water.
