The Mechanical Engineering course at the University of Campinas is composed of different disciplines in the areas of materials, mechanical design, manufacturing (production and manufacturing), computational systems, thermal and fluids. In the manufacturing area, in particular, there is a discipline entitled Productive Systems whose main objective is to offer to the student a global vision about operations management. In the field of operations management, sustainability is gaining more and more importance; thus, it is important to develop in the students a critical sense about social and environmental aspects. Thus, this paper aims to present the main initiatives developed in the discipline to promote sustainability in engineering students.

Since 2015, the professors responsible for the Productive Systems discipline, assisted by post-graduate students and professors from other universities, have begun to redesign the discipline, including debates, lectures, projects and other initiatives to provide a critical view concerning the traditional concepts taught. The discipline has been performed three times with this new conception. The methodology to structure this research was literature review, documental analyses of the discipline records and meetings with professors that participated in the initiatives. An Action Research approach was performed by two professors and a graduate student. The authors of this paper also compared the results with those obtained by initiatives performed at Chalmers University of Technology (Sweden).

This study allowed to reinforce some results from initiatives performed at Chalmers University of Technology (Sweden); however, some differences were identified. For example, similar to the initiatives mentioned, the professors of University of Campinas had problems with didactic books, as they loosely integrate the basic operations management concepts with sustainable development fundamentals. On the other hand, debates related to social sustainability were considered positive from the point of view of the professors and students, differing from initiatives performed at Chalmers University of Technology.

Results come from one field study (University of Campinas) when professors of the Mechanical Engineering course try to integrate operations management concepts and sustainable development. Different results may be observed by other higher education institutions.

The authors of this paper believe that the diffusion of these initiatives can stimulate other professors and researchers in the field to broaden the academic debate about the insertion of sustainability into engineering courses.

There are few papers presenting didactic experiences and empirical results about the integration of operations management concepts and sustainable development. Results of this paper reinforce some good practices and they also present other ones, in a way that extend the debate about educational engineering.

E-commerce platforms offer service guarantees (SGs) to improve consumers’ perceived quality and satisfaction. This survey aimed to test the direct and indirect effects of SGs on consumers’ perceived quality and satisfaction concerning the services of an international e-commerce platform.

The survey sample consisted of 378 consumers of an international e-commerce platform. Structural equation modelling (SEM) tested two structural models.

The first hypothetical model demonstrated that SGs positively and directly affects perceived quality and consumers' satisfaction on an e-commerce platform. This model also revealed that the perceived quality directly and positively impacted consumer satisfaction. The second hypothetical model confirmed that perceived quality mediates the relationship between SGs and satisfaction. Moreover, SGs positively and indirectly impacts consumer satisfaction.

This study suggests that e-commerce platforms use SGs as a marketing strategy in their business models to increase perceived quality and consumer satisfaction. However, to positively impact the perception of quality and consumer satisfaction, such SGs must have the following characteristics: unconditional, easy to understand and communicate, meaningful, easy and painless to invoke, and easy and quick to collect.

This research demonstrated the direct effects of SGs on perceived quality and consumer satisfaction on an international e-commerce platform. SGs directly impacts consumer satisfaction with the platform, even if they have not experienced its quality attributes (reliability, customisation, security and design). The indirect effects of SGs on consumer satisfaction were also proven, mediated by perceived quality. No previous study demonstrated such relationships simultaneously on e-commerce platforms.

The purpose of this paper is to analyze the perception of the influence of greenwashing and of attitudes and beliefs in the decisions of purchase of green products in the retail.

A quantitative research was carried out by means of a survey with a sample of 880 consumers living in São Paulo city, Brazil, who buy in supermarkets weekly or biweekly.

It was possible to evaluate a model that analyzed the aspects that greenwashing carries and the aspects that the attitudes and beliefs of the consumer present. As a result, it is inferred that when greenwashing is identified in the product, it loses the aspects of loyalty, satisfaction and benefits, as well as becoming a product that causes confusion of consumption. Further, consumer attitudes and beliefs show that they are guided by the aspects of perceived loyalty, satisfaction and benefits and that the perceived risk aspect is practically ignored.

The originality of this study is in evaluating consumer perception focusing on several aspects of purchase intention simultaneously, considering perception and behavior of consumer before greenwashing and green consumption and using all aspects together (satisfaction, loyalty, subjective and control forces, risk and benefits perception). Besides complementing with other determinants like consumer attitudes and beliefs, confusion of green consumption, behavior controlled in relation to green consumption and greenwashing. Thus, it contributes with an interdisciplinary study whose scale and methodology can be used by analogous studies.

The purpose of this paper is to evaluate the main factors that influence the organizational change in a steel company.

The methodological procedures used were literature review and survey. The literature review allowed the listing of 24 factors and these factors were grouped into three constructs (Behavioral Aspects, Cultural Aspects and Management Aspects). The survey allowed the quantification of each factor based on information provided by employees who work in the mentioned company. The data collected were analyzed using the Partial Least Squares-Structural Equation Modeling technique.

For the Behavioral Aspects, the following factors were validated: fear of the unknown; insecurity and anxiety; stress and feeling of suffering. For the Cultural Aspects the following factors were validated: multiculturalism in the company; low degree of risk acceptance and low performance acceptance; excessive concerns about consensus. Finally, for the Management Aspects, the following factors were validated: lack of clarity in communications; lack of alignment of goals; lack of leadership engagement.

The results are valuable for the company studied and for other managers interested in subject. The findings presented here can broaden the debate about this topic and contribute with professionals that wish to evaluate the mentioned factors.

Manufacturing systems have undergone radical changes because of the implementation of physical and digital innovating technologies with high levels of connectivity, interoperability and autonomy. In this regard, the objective of this study was to investigate whether industrial engineers graduated in recent years in Brazil are prepared or not to work in companies and industries within the scope of Industry 4.0 technologies in a way that they positively contribute to the implementation and management of such technologies.

To achieve these objectives, a literature review and a survey on managers of the industrial sector acting in Brazil were carried out as the research strategies. The data collected were analyzed through a quantitative approach by means of the structural equations modeling method.

The hypothesis that the competencies of industrial engineers currently graduating in Brazil have a positive impact on the implementation and management of Industry 4.0 technologies has been confirmed. Predicting the evolution of production scenarios, understanding the interaction between organizations and their impacts on competitiveness and keeping abreast of technological advancements, organizing them and putting them to the service of business and societal demands were the competencies that obtained the highest factor loadings in the construct of industrial engineer competencies. In addition, cloud manufacturing, automation and robotization were the competencies that obtained the highest factor loadings in the industry 4.0 construct.

The analysis of skills development stands out as a source of competitive advantage for companies that intend to transition to a production system aligned with the principles of Industry 4.0, considering the training of professionals in an emerging economy context.

The purpose of this paper is to integrate Brazilian agro-industrial co-operatives’ horizontal, lateral and vertical integration diversification and expansion strategies, such as operation area and membership, with financial models. Several studies have tried to assess the importance of diversification on the financial outcomes in agricultural co-operatives with limited success.

The three main concepts were combined in a working model. A survey was developed to gather data on financial, diversification and expansion strategies from 67 co-operatives (44 per cent return rate). Data were processed using a partial least squares structural equation model.

The findings suggest that expansion is directly responsible for both the financial output and diversification strategy; however, no hard evidence supports the view that the diversification of production in some agro-industrial co-operatives leads to positive financial results.

Only larger Brazilian co-operatives (>$50m in annual revenues) were considered. Co-operatives facing other scenarios or smaller co-operatives could have different outcomes.

Besides diversifying their co-operatives for financial reasons, managers should also consider risk aversion and adapting to new farmers’ portfolios as probable reasons.

Extant literature asserts that diversification leads to financial growth; as the co-operatives studied show no such causal relationship, it follows that they diversify their portfolios for other purposes.

The purpose of this paper is to analyze the difficulties observed during implementation of quality management systems (QMSs) in Brazilian manufacturing companies.

The methodological strategy used was a literature review, a panel of experts and a survey. Through the literature review, 15 difficulties associated with the implementation of QMS were raised; these were organized into latent variables by specialists in the subject and served as the basis for a survey. In total, 123 professionals working with quality management in manufacturing companies participated in the research and the data collected were analyzed by means of second-order confirmatory factorial analysis.

The results allowed the validation of the 15 difficulties observed in the literature, and it was evidenced that these difficulties are structured in four latent variables as follows: difficulties associated with employees; difficulties associated with QMS structuration; difficulties associated with integration; and difficulties resulting from the planning.

The main limitation of this research is the sample size, because 123 professionals that work with quality management in manufacturing companies participated in the research. It should be noted, however, that all parameters evaluated through the second-order confirmatory factorial analysis were validated.

The findings have great value for both quality management professionals, who may use those findings to guide the pre-implementation phase of a QMS, and researchers, who may use those findings as a foundation for future studies, in the development of models or tools related to QMS implementation.

No other paper was found on the scientific basis with the same focus for Brazilian manufacturing companies, thus demonstrating originality. The value of the research lies in the fact that the results presented here, statistically validated, may be used by other researchers and market professionals.

Companies' relationship with their customers through e-commerce platforms has increased considerably in the past few years, bringing new challenges concerning service guarantees (SG). This study aims to propose a framework of the relations between customers' expectations on SG, their negative experiences and their attitudes and behavioural intentions towards an e-commerce platform.

The research had a qualitative and descriptive approach. Testimonials from clients of an online e-commerce platform were obtained through interviews via videoconference and non-participant observation on a complaints website in Brazil. The testimonies were analysed through content analysis.

The customer expectations regarding the SG offered by the e-commerce platform are congruent with the five categories of the theory that support this research. Customer testimonials on the complaints site show that their negative experiences with the e-commerce platform generated negative emotional, cognitive and behavioural responses towards the company. A framework was proposed, including customers' expectations regarding SG, their negative experiences and their repercussions on clients' attitudes and behavioural intentions.

This article is the only that contemplates customers' expectations about SG in an e-commerce platform, relating them to attitudes and behavioural intentions. Thus, its framework demonstrates the relationships between customer expectations about SGs, their negative experiences and attitudinal and behavioural repercussions. This article brings academic and managerial contributions for companies and managers of e-commerce platforms. It contributes to clients and consumer protection associations by revealing problems they face with SG on e-commerce platforms. This research can be used by those responsible for elaborating laws and public policies to regulate and inspect the relationships between e-commerce platforms and their customers.

The purpose of this paper is to identify what are the main causes that lead strategies to decline at execution phase.

The paper adopted the strategy of survey with the 69 Brazilian businessmen. The questionnaire was developed from 16 causes pointed out in the literature and the results analyzed using Cronbach’s α coefficient, multidimensional scaling, exploratory factor analysis and Pearson correlation coefficient.

The results of statistical analysis showed that the main causes are primarily associated to leaders’ defaults during execution strategies, lack of support and feedback of senior management, no involvement of the teams during the strategies formulation, failure of communication on the strategic objectives in all organizational levels, and others.

The 69 businessmen work in different sectors and there may be specific causes for each sector. The research presented by this paper did not have objectives to analyze specific sectors of the economy.

The results are extremely important and useful for managers during the implementation phase of the strategies and researchers in the field of business strategies.

There are no research with the same focus and objective presented by this paper about Brazilian companies.

The purpose of this paper is to discuss how COVID-19 pandemic forced several companies to reflect on their activities. Many organizational changes have been conducted and others will still be necessary. Some reflections are presented, as some aspects are well consolidated in academic literature while they are neglected by many leaders of companies. The authors believe that this viewpoint can support leaders to enhance organizational development.

Part of the information presented here is characterized by the authors’ points of view, as it is a viewpoint. However, the authors carried out searches on scientific bases and published press reports aiming to support the reflections presented in this text.

The reflections presented in this viewpoint focus on the following aspects: periodic critical analysis of companies business models, business continuity management systems, risk management, resilience principles in supply chain management, necessary changes in production systems, occupational health and safety systems and new ways of working. For the authors, the correct conduction of these aspects can guarantee companies survival; however, many leaders worldwide still neglect them.

The reflections presented here can be useful for leaders interested in conducting a critical analysis in their business, considering necessary organizational changes to face the COVID-19 pandemic consequences.
