Football is significant in the global economic context. However, the same significance is not identified in the value added to the chain, as the elements that make it up act in a disintegrated and independent manner with undesired effects. Consequently, it is necessary to structure the undesired effects to seek the basic causes that sustain this problematic situation. Thus, this paper aims to use a CRT to structure the undesired effects and basic causes that limit the positive economic impacts of the south Brazilian football value chain.

A semi-structured questionnaire was applied with questions about the existing constraints. Based on the answers in the interviews, the current reality tree was elaborated, premised on identifying the basic causes that sustain the undesirable effects detected.

Among the main results, it was identified that management problems of the traditional leaders of football clubs and federations are considered the main reason why south of Brazil football cannot fully exploit its economic potential.

It is evidenced that the paper shows the undesired effect that has the most impact on the development of this chain, and it is important to propose improvements to its root causes, aiming at greater efficacy of the resulting actions.

The purpose of this paper is to investigate the relations in the Marketing/Operations interface through the analysis of data of the operational reality of a Brazilian company with a low technological intensity. The study aims to quantify and determine the impacts of marketing decisions on delivery performance and on flexibility of the operations area.

A longitudinal case study was conducted and the variables used in the model were derived from established theories and were evaluated with artificial neural networks. The case of a food manufacturing company was selected to reflect the relations in the marketing/operations interface of a low technological intensity enterprise.

The results show that the decisions on Place/Channel, Price and Product dimensions of marketing exert a significant impact on flexibility and delivery performance of the operation area.

The findings of the case study cannot be generalised and the outcomes are specific to just one firm. However, the approach lends itself to replication, particularly within low technological intensity companies.

Prior studies have focussed on coordination among functional areas as marketing and operations at higher levels of abstraction. The study contemplate empirical propositions through the data analysis of a company with a low technological intensity that can be used to improve managers' decisions and alignment in the Marketing/Operation Interface.

The purpose of this paper is to longitudinally assess the technical efficiency and productivity, considering investment projects and technological change, in a second-generation petrochemical company.

The study uses data envelopment analysis (DEA) together with the Malmquist index to measure efficiency during the analysis periods. The working method consists of four main phases, namely development of the conceptual model, construction of the mathematical model, application of model to the case, and analysis of the results. The study utilizes a quantitative approach with descriptive goals seeking to evaluate the impacts of technical changes on the operational efficiency and productivity of the production process.

The use of DEA associated with the Malmquist index proved to be viable for analyzing a single company and identifying efficiency improvements, as well as the impacts of the learning process and the implementation of improvement projects. However, the results of the improvement projects and learning process were not representative and had no statistical significance on the actual change in efficiency of the company during the periods analyzed. For the case in question, the learning process and continuous improvement were not observed during all study periods.

The proposition that the improvement projects and investments implemented increased the efficiency of the company was rejected. Hence, with this work, it was possible to determine that the company unnecessarily invested resources in projects to increase efficiency. Furthermore, the company could have explored more internal resources before making significant investments in increased efficiency.

As for the value of this research in the theoretical and academic scope, this paper advances knowledge on the application of DEA because it proposes to establish an internal reference benchmarking for comparison. The literature contains few studies that analyze organizations using continuous processes, such as petrochemical processes, in longitudinal studies as a function of time, especially with the use of DEA.

Football is deployed into various segments and consists of a complex value chain, with interrelationships and circularities. It is relevant in various segments and therefore it is important to understand the structure. Thus, the purpose of this paper is to present a model of a football value chain and the managerial implications inherent to this chain.

This research used a field study as its methodology, developing a semi-structured questionnaire containing open-ended questions about the representativeness of the football value chain. In-depth interviews with specialists in football were performed to collect data.

The results of the interviews indicated that the theoretical model is representative. Furthermore, through validation, the relevance and representativeness of the football value chain was shown, as well as its interrelationships with the other commodity and service segments. In addition, it was found that this segment is relevant and influential in the national and international market, and can be considered a factor of economic and social development.

This paper provides a view of the actors who make up the football value chain, and also supplies a complementary view to the models of chains presented in the theoretical review, enabling the provision of evidence on the axis with greater added value as a new step. The limitation of this research involves the context approached, because as identified throughout the investigation, this context is complex and dynamic. In this way, the linear approach used to construct this chain led to a reduced view of reality and of present relationships.

The model shows the presence of the main actors and the structure for the transformation of raw material into a final product, and is useful to understand the existing relationships and the layers of added value.

The evaluation of the conceptual model of football value chain confirms that this is a professionalized chain, which generates a significant number of direct and indirect jobs.

The authors propose a model of a football value chain which is complementary to the theoretical review developed, exposing a linkage of the players present in this chain and at what stage they are present, and supplies the managerial implications inherent to this.

The paper aims to present a case of integration between process engineering and the thinking process of the theory of constraints (TP‐TOC) through the analysis of an organization's processes, pointing out the complementary aspects between the two theories and their benefits for the organization.

The paper has used an Institution of Higher Education as its case study. The research has started by identifying the processes of the institution and choosing one to model according to the process engineering approach. The process was then analyzed through the elaboration of the current reality tree technique. After the analysis, the evaporating clouds technique was applied in order to breach the assumptions that were avoiding the problems to be solved. Finally, the process has been redesigned based on the results of the previous steps.

The analysis of this case contributes towards understanding and identifying the causes of the current problems in the studied processes, providing a systemic and systematic view through the proposed approach.

The paper proposes an approach that enables a systematic and systemic analysis of organizations' processes through the use of process engineering and the TP‐TOC.

The aim of this study is to analyze the capitals moved in decisions about sustainability in narratives from and referring to Samarco Minerações, S.A. under a perspective guided by Bourdieusian sociology.

Oriented by historicist ontology and historical epistemology, this research is classified as qualitative, descriptive and documentary, with narrative analysis and case study. The selected organization-case was Samarco Minerações, S.A. The documentary sources considered were sustainability reports, social networks channels and news published in Brazilian newspapers of high circulation. The collected information was submitted to the narrative analysis method.

Samarco Minerações, S.A. maintained the sustainability posture before and after the ore tailings dam rupture. The decision models adopted (decentralized) and the moved capitals (economic and technological) after the ecocide revealed a change in the organizational practices in front of a new instability scenario, and the organization’s attempt to reach acknowledgment, legitimacy and power.

The organization was selected because of its involvement in an ecocide. The crime generated economic (suspension of tax collection caused by the organizational inactivity), social (unemployment and deaths) and environmental (iron ore tailings contaminated the region’s ecosystem) impacts.

The greatest value and contribution this paper offers is an alternative intermediary methodological approach using Bourdieusian micro-sociology to analyze narratives based on capitals dynamics and doxa. This theoretical and methodological approach can prove fruitful for further research in sustainability studies on other topics, and even in other fields.
