Goal: The need to discuss reverse logistics processes with a detailed and analytical approach, aiming at improving the reverse channel efficiency is notorious in the literature. Therefore, this research aimed to analyze and describe in detail the activities that make up the reverse logistics processes and, in addition, to propose a conceptual framework for a better understanding and definition of RL processes. . Design / Methodology / Approach: This was achieved through a systematic review, which considered 3.517 papers, analyzing the RL concepts, definitions and objectives, as well as identifying its processes and activities. The activities were categorized as information (I-RL process) or materials (M-RL process) related. Results: This research provides an entire RL activities blueprint. This approach promotes greater transparency, allowing to identify stages most impacted on the reverse channels, besides standardizing logistical procedures and also allowing to insert control points for measuring performance. Limitations of the investigation: It is possible for a paper that focuses on one of the activities of the framework not to have been shown during the database if it doesn’t mention the keywords “reverse logistics”, “green logistics” and “sustainable logistics”. Practical implications: The concepts of reverse logistics activities presented in the framework can be implemented in reverse supply chains, serving as a basis for organizational strategies for managers involved with such processes. Originality / Value: The authors of this paper believe that the results achieved can greatly contribute to the expansion of debates in the RL area, as well as serve as a basis for managers involved with RL processes.

Background: The wide variety of terms that converge in reverse logistics have been more evident and discussed in the current context of the literature, such as reverse channels, reverse supply chain, closed-loop supply chain, and circular supply chain. Regarding this, this paper aimed to investigate the level of uncertainty about the activities that make up the Reverse Logistics process in the opinion of professionals working in this area in Brazil, to develop a discussion relating to the sustainable development goals proposed by the UN and their importance for the future of logistics networks. Methods: Initially, through a detailed systematic review of the literature, the activities that make up the RL processes were identified. Then, a questionnaire was elaborated on regarding such activities, and a survey was developed with professionals in the area. The data obtained were analyzed through a descriptive analysis of means, calculation of Cronbach’s Alpha, and using the multicriteria decision technique TOPSIS. Results: It is possible to see that professionals involved with RL processes in Brazil still have many doubts regarding which activities belong to the RL process. In the opinion of Brazilian professionals, 10 of these activities have generated high levels of uncertainties about their belonging or not to the RL process. On the other hand, with a low level of uncertainty, 3 activities were not considered and 3 were considered to make up the RL process. Conclusions: It is believed that this study can contribute to the generation of knowledge by comparing basic information in the scientific literature with the practical knowledge of professionals belonging to the reverse logistics sector working in the Brazilian context.

Achieving sustainability performance seems to increasingly occupy the strategic agendas of organizations. But, are organizations investing in their strategic agendas in the 3 dimensions of this Sustainability? Would this Sustainability performance (Environmental, Social and Economic) be favored by the development of innovative dynamic Capabilities (Sensing, Seizing, Transforming) in a prolonged way? The existing literature brings results of researches focusing on another one of these dimensions, in a combination of these, or even, they bring inconclusive results. The main of this research is to analyze the effect of innovative dynamic capabilities on Sustainability performance (Environmental, Social and Economic). The hypothesis we have adopted is that the development of innovative dynamic capabilities (Sensing, Seizing, Transforming) favor Sustainability performance over time. For that, we used a longitudinal multiple linear regression analysis of data from the Innovation Research in Brazil (PINTEC), for the period 2003-2014, with a sample of 48 productive sectors (extractive, transformation and services industry) and 244 observations. As main research findings, we highlight that Sensing and Seizing capabilities favor Economic Sustainability performance and Seizing favor in Social Sustainability, the same not true for Environmental Sustainability. Also, the Transforming capability did not show absolute results on any of the dimensions of Sustainability, showing partial association for Economic, Environmental and Social Sustainability. For the economic dimension, innovative dynamic capabilities favor Sustainability and therefore, our findings confirm that the economic mindset is still prevalent.

RESUMOO setor de serviços na atualidade tem uma grande importância econômica na maioria das regiões do globo. Com suas particularidades, a principal característica do serviço é que o mesmo se envolve diretamente com seu cliente final, o que se faz necessário inovação estratégica dentro de seus processos, para que sua competitividade a frente do mundo globalizado não seja afetada. Muitas são as ferramentas e abordagens para que as melhorias nestes processos ocorram. E uma em especial, denominada lean seis sigma, vem ganhando espaço dentro de grandes organizações da manufatura e de alguns serviços, como os de saúde e bancários. Porém ainda fica bastante implícito dentro da literatura como essa metodologia que combina outras duas -lean e seis sigma -pode trazer resultados satisfatórios para as empresas e como esta combinação acontece de fato. O objetivo deste trabalho é, por meio de uma revisão sistemática da literatura, mapear, analisar e discutir a adoção do lean seis sigma no âmbito dos serviços, utilizando uma classificação com diversos parâmetros que visam identificar um panorama geral da literatura sobre este tema. Foi adotado um método sistemático de revisão onde foram mapeados 30 artigos sobre adoção lean seis sigma em serviços e a partir da leitura destes com a extração de dados pré-definidos. A partir desta etapa os estudos foram analisados quantitativamente e discutidos qualitativamente para compreender o estado da arte sobre a combinação lean seis sigma dentro dos mais diversos tipos de serviços. Ao final deste trabalho encontram-se algumas considerações sobre a metodologia lean seis sigma a partir dos resultados encontrados na
