The pace of development in the world of 5G communication systems has proven to be much more demanding than previous generations, with 5G-Advanced seemingly around the corner [1]. Extensive research is already underway to structure the next generation of wireless systems(i.e. 6G), which may potentially enable an unprecedented level of human–machine interaction [2].

Organizations have been striving to demonstrate to society their political of good social and environmental practices. Thus, socially responsible investments have been increasingly significantly, one of the reasons for increasing creation of indexes of corporate sustainability. Many studies have been done about the ISE - Corporate Sustainability Index - of BM&FBovespa, verifying if the portfolio composed of sustainable companies brings higher return to shareholders than other portfolios of regular companies. However, most of these researches focus on the stock value and there are few studies that give focus on fundamental analysis. The main purpose of this paper is to compare fundamentalist profitability indicators among a group of companies that compose the ISE index and a reference group, verifying if sustainable management improves business profitability and how it creates value for shareholders. The groups were compared and the evidences found show that despite the ISE have a differentiated theoretical portfolio, focused on social, environmental and ethical issues, the profitability of companies that compose the index is similar to or lower than the profitability of companies of the reference group. Nevertheless, the results show that the ISE Group has other ways to create shareholder value, as lower volatility and lower risk exposure.

In the last few decades the competitive context development trajectory is leading companies to increase their contribution for sustainable development. Stakeholders' accountability demands are being reflected in present multidisciplinary regulatory framework that is formed by standards, guidelines and guidance reports, and allows markets and society to have evidences from sustainable behavior, which is certified or formally agreed or signatory by companies. Operations strategy performance information could be addressed to a set of evolutionary performance indicators, which could represent sustainability present performance, and also could orient companies in reaching higher performance levels according to a preset maturity trajectory. The objective of this paper is to develop a process for generating an integrated set of performance measures for managing sustainability at value chain or operations system level. An applied research was conducted based on action research approach, operationalized by Cambridge process or engineering approach, and managed in research process management cycle. Performance measures are formally and detailed defined as metadata. Process application not only allows a better understanding on how sustainability indicators could be integrated and related to a maturity model, but also created an information system that could be used for auditing, assessment and reporting sustainability performance.
