Abstract

Purpose

This paper aims to assess the combined application of Lean Six Sigma and agile approach for optimizing operational processes of order management in the seed industry.

Design/methodology/approach

This study is based on an action research case conducted in a multinational Brazilian Seeds Business enterprise. This paper reports on the application of the Lean Six Sigma define-measure-analyze-improve-control (DMAIC), using the steps of DMAIC cycle as a sprint of agile approach. The methodology involves outlining an operational process through sequential activities, each associated with a cycle time, equivalent number of full-time employee and number of orders. Performance metrics for the order management process include continuous monitoring of these activities, using monitoring systems, management software and manual records to collect data.

Findings

The findings reveal significant improvements in critical-to-quality measures related to customer care, planning and logistics. The implementation of the DMAIC methodology and agile approach resulted in tangible enhancements in cycle time, defects per opportunities and overall process efficiency. The results allow the classification of defects, the identification of their causes and, consequently, the presentation of a control plan to mitigate these problems. Furthermore, the study identifies key causes of operational issues and proposes a prioritized action plan.

Research limitations/implications

The limitation of this research is its restriction to a single case. The external validity of the results and generalizability to other organizational contexts may be compromised due to the lack of case diversity. The fact that the research focuses on a single company, even if it is a large multinational company, may limit the applicability of the findings to different sectors, sizes and organizational structures, which may be an opportunity for future research.

Practical implications

The findings suggest that the integrated approach of DMAIC and agile methodology contributes to a culture of continuous improvement and operational efficiency. The systematic collection and analysis of data enhance evidence-based decision-making, providing a robust foundation for strategic and operational choices. Moreover, the successful integration of methodologies presents a comprehensive framework applicable to diverse organizational challenges.

Originality/value

The paper applies action research to understand and address operational challenges, emphasizing practical solutions. The integration of DMAIC and agile enhances the depth of process analysis, enabling the identification, implementation and control of improvements. This study offers a significant contribution both to practitioners, providing practical implications, and to academics, enriching the Lean Six Sigma and agile body of knowledge.

Abstract

Purpose

The aim of this study was to evaluate the performance of fuel flow processes in a network of eight gas stations, located in the mesoregion of Alto Paranaíba and Triângulo Mineiro.

Design/methodology/approach

Two multi-criteria decision support methods were applied, respectively, of a statistical and mathematical nature, namely, Principal Component Analysis (PCA) and Data Envelopment Analysis (DEA). The research method used was quantitative, with a brief complement of qualitative research, and descriptive in purpose, supported by the inductive method. The data collection stage took place with the support of interviews, with the application of a structured questionnaire, and non-probabilistic sampling, for convenience.

Findings

It was possible to verify that the gas station that stood out the most was station 2 (GS2), which achieved maximum efficiency, a fact that can be justified by the analysis resulting from the application of PCA, as for the product purchase variable (PP), the GS2 is the one that buys the most fuel, and is also the one with the largest storage capacity (C), and the highest volume of product sales (PS), which suggests signs of balance between supply and demand for this station, justifying its prominence.

Research limitations/implications

The limitations of the study were related to the DEA technique, which requires a number of variables/indicators three times smaller than the number of DMUs considered, and the difficulty in obtaining financial data on the DMUs analyzed. Considering the security and anonymity of the gas station network, it was not possible to use this data.

Practical implications

The performance assessment of fuel flow processes carried out in this study promotes the efficient use of available resources as well as identifying efficient DMUs that represent benchmarks for improving management processes and performance of inefficient DMUs.

Social implications

From a social perspective, this study promotes the improvement of the quality of flow processes and effective management of the fuel supply chain, ensuring the safe storage and transportation of fuels to customer supply. Performance management in this sector moves other sectors of the economy, since an efficient unit represents a balance between supply and demand, and consequently, boosts the regional economy, promoting economic growth of the population. Hiring qualified labor for this purpose also represents one of the implications of the study. From an environmental perspective, optimizing flow processes generates a reduction in greenhouse gas emissions and encourages the formulation of public policies aimed at consolidating sustainable practices.

Originality/value

Performance management applied to the context of the fuel supply chain is a relevant topic that has been little explored in scientific research, with a low level of information detail. This study using the inductive method allows the generalization and replication of this management pattern in other organizations in the sector in order to increase the efficiency of the fuel distribution system, with the perspective of maximizing outputs and reducing input consumption. In this aspect, the study introduces possibilities for advancement in social and environmental perspectives based on the effective management of fuel logistics.

Abstract

Purpose

This paper explores Lean Six Sigma principles and the DMAIC (define, measure, analyze, improve, control) methodology to propose a new Lean Six Sigma 4.0 (LSS 4.0) framework for employee occupational exams and address the real-world issue of high-variability exams that may arise.

Design/methodology/approach

This study uses mixed methods, combining qualitative and quantitative data collection. A detailed case study assesses the impact of LSS interventions on the exam management process and tests the applicability of the proposed LSS 4.0 framework for employee occupational exams.

Findings

The results reveal that changing the health service supplier in the explored organization caused a substantial raise in occupational exams, leading to increased costs. By using syntactic interoperability, lean, six sigma and DMAIC approaches, improvements were identified, addressing process deviations and information requirements. Implementing corrective actions improved the exam process, reducing the number of exams and associated expenses.

Research limitations/implications

It is important to acknowledge certain limitations, such as the specific context of the case study and the exclusion of certain exam categories.

Practical implications

The practical implications of this research are substantial, providing organizations with valuable managerial insights into improving efficiency, reducing costs and ensuring regulatory compliance while managing occupational exams.

Originality/value

This study fills a research gap by applying LSS 4.0 to occupational exam management, offering a practical framework for organizations. It contributes to the existing knowledge base by addressing a relatively novel context and providing a detailed roadmap for process optimization.

The study focused on the impact of microcredit on the short-term finances of microentrepreneurs at the Galerías Shopping Center in San Juan de Pasto, Colombia, from 2019 to 2023.

Abstract

Purpose

The study focused on the impact of microcredit on the short-term finances of microentrepreneurs at the Galerías Shopping Center in San Juan de Pasto, Colombia, from 2019 to 2023.

Design/methodology/approach

The design of the paper is empirical-analytical, focusing on the tangible and unique aspects of reality that can be fragmented for measurement. This approach privileges the use of data from the study population’s experience, which is treated analytically through statistics to establish frequencies and correlations between variables. The research involved a structured questionnaire based on bibliographic references and considering the operational framework of the variables, which underwent expert review, necessary adjustments, a pilot test and subsequent validation in 2019 and 2023. The reliability of the instrument was assessed using Cronbach’s alpha, ensuring a reliable indicator when equal to or greater than 0.7 in each analysis period. This methodology aimed to identify practices and how the financial profile influences short term.

Findings

The findings from the survey conducted with the microentrepreneurs at Galerías Shopping Center reveal several significant connections to the theoretical framework. The study revealed that many microentrepreneurs relied on their personal funds for business financing, indicating a limited understanding of financial principles. Additionally, a significant portion of microentrepreneurs mitigated investment risk by securing loans from financial institutions, yet none utilized government subsidies like entrepreneurship loans, pointing to a lack of advice. The findings underscore the importance of financial education and suitable financial services for business development.

Research limitations/implications

One limitation of this study is the lack of detailed data on the financial structure of microentrepreneurs' businesses, as well as specific information on interest rates and the terms and conditions of the microcredit used. These limitations may affect the generalization of the results and the comprehensive understanding of the impact of microcredit on the short-term finances of microentrepreneurs. Future research could include a larger sample size and more accurate data on the financial structure of businesses, as well as a detailed investigation of interest rates and terms and conditions of microcredit, to provide a more comprehensive understanding of the financial impacts for microentrepreneurs.

Practical implications

The findings of this study have practical implications for microentrepreneurs in the Galerías Shopping Center. The research emphasizes the need for improved financial knowledge, accounting practices and debt management among microentrepreneurs. It also highlights the importance of financial education and access to suitable financial services for business development. The study’s insights can guide the development of training programs and initiatives aimed at enhancing financial literacy and financial management among microentrepreneurs, leading to more informed decision-making and improved financial outcomes.

Social implications

From a social perspective, this research contributes to promoting economic development and financial inclusion. By addressing the mismanagement of microcredit by microentrepreneurs and providing insights into their short-term finances, the study aims to foster economic empowerment and sustainable development within communities. The findings underscore the significance of microfinance in driving economic growth, reducing poverty and promoting social inclusion. The research emphasizes the importance of equitable access to financial services, which can contribute to narrowing the gap between the financially excluded population and the conventional financial system.

Originality/value

This research adds originality and value to the academic community by addressing the incidence of microcredit on the short-term finances of microentrepreneurs in the specific context of the Galerías Shopping Center in San Juan de Pasto, Colombia. By characterizing the financial profile of microentrepreneurs, establishing the relationship between microcredit characteristics and the financial profile and proposing an action plan, the study provides valuable insights for decision-making in both the academic and microfinance fields. The research contributes to the existing literature on microfinance and financial inclusion, offering a unique perspective and potential solutions for optimizing the use of microcredit-funded resources by microentrepreneurs.

Abstract

Purpose

The present work investigated the effect of corporate social responsibility and top management support on employee ecological behaviour (EEB) with the mediating role of green culture and green commitment. Social identity theory (SIT) was used to describe the association between green culture, green commitment and EEB. Further, a conceptual model that summarises the interaction between perceived corporate social responsibility, top management support, green commitment, green culture and the adoption of ecological behaviour was developed.

Design/methodology/approach

The paper opted for a quantitative design using convenience sampling by collecting the data through a structured questionnaire gathered from 308 academics working in five Malaysian higher education institutions.

Findings

Corporate social responsibility and top management support positively influence green culture and commitment. Moreover, green commitment positively influenced EEB and fully mediated the relationship between corporate social responsibility and EEB and between top management support and EEB.

Research limitations/implications

The academic staff of universities was the target population of this research. Nevertheless, universities have a diverse population with complex activities that can affect the implementation of a sustainable workplace within the campus. Future research should also examine non-academic staff, including administrative, technical and operational staff, due to different employees' perceptions.

Originality/value

As far as the authors know, this is the first study to assign the mediator role to green culture in a relationship between top management support and EEB amongst academic staff in the Malaysian context. Future research should consider other intervening variables that influence adopting ecological behaviour.

This paper aims to explore the impacts of a blockchain network implementation to support purchasing processes of a Brazilian public organization.

Abstract

Purpose

This paper aims to explore the impacts of a blockchain network implementation to support purchasing processes of a Brazilian public organization.

Design/methodology/approach

The Grumbach method was used to build the scenarios. Five experts with knowledge in blockchain and experience in public procurement were consulted on 20 possible preliminary events, defining their probability of occurrence and relevance. The data obtained were processed in Puma software, which returned a selection of ten definitive events, based on probability, relevance and standard deviation indicators, generating a map of prospective scenarios.

Findings

Three following scenarios are shown, the ideal scenario, the one with greater implantation benefits and fewer complications; the trend scenario, more likely to occur under current conditions; and the most likely scenario of occurrence, according to experts. The results indicated which simulated events are drivers (motives), and which are influenced (dependent). They were categorized as opportunities or threats to the deployment of the technology.

Research limitations/implications

Although public procurement processes are standardized by Brazilian legislation, new events may arise from the replication of the model in different organizations. The research revealed the need for practical testing in a simulated public procurement environment.

Originality/value

The article explores the interaction between disruptive network technology and processes linked to public sector efficiency. Studies on electronic government point to the future of public management.
