This research evaluates the influence of the Brazilian accreditation methodology on the sustainability of the organizations. Critical factors for implementing accreditation were also examined, including measuring the relationships established between these factors in the organization sustainability. The present study was developed based on the survey methodology applied in the organizations accredited by ONA (National Accreditation Organization); 288 responses were received from the top level managers. The analysis of quantitative data of the measurement models was made with factorial analysis from principal components. The final model was evaluated from the confirmatory factorial analysis and structural equation modeling techniques. The results from the research are vital for the definition of factors that interfere in the accreditation processes, providing a better understanding for accredited organizations and for Brazilian accreditation.

As the lean product development (LPD) process is responsible for maximizing the value/waste relation by encouraging different types of innovation, it needs a clear understanding of end customer value. Moreover, lean systems engineering is related to the application of lean thinking (LT) in systems engineering to improve the delivery of value to all stakeholders of the system. Then, faced with this scenario, this research aims to propose a value-adding conceptual model for incremental product innovations in LPD. A systematic review of the literature from the LT perspective was performed and the conceptions of value were identified and then analyzed and contrasted with the concepts and characteristics of the areas of product development, marketing, and consumer psychology, which made possible the proposition of a conceptual model. The results show that customer value is multidimensional, and it was possible to identify the importance and the need for prioritization of certain dimensions of value for specific markets and customers. The conceptual model named VA2I presented in this study is generic and can be adapted and applied in any type of organization.
