PurposeSeveral authors have examined the lean healthcare literature, but besides all efforts made, articles comparing conceptual and analytical studies were not found. Thus, a systematic review is conducted aiming to understand the state of the art of lean healthcare by investigating and comparing how conceptual and analytical articles address tools/methods, application fields, implementation barriers and facilitators and positive and negative impacts.Design/methodology/approachArticles in English about lean healthcare, published in journals in the last ten years (2009–2018) and indexed in Web of Science (WoS) or Scopus were examined and assessed by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) protocol. A qualitative content analysis on the eligible articles was conducted, and results from the conceptual and analytical studies were compared.FindingsThere is a literature gap regarding tools/methods in both conceptual and analytical approaches once they prioritize for different items. Barriers, facilitators and negative impacts are perceived differently within both categories and might require more extensive analysis. The same items prevail in both conceptual and analytical categories when analyzing healthcare fields and positive impacts.Originality/valueThere is a lack of articles comparing conceptual and analytical studies concerning lean healthcare. So, this study's relevance is in identifying theoretical and applied research gaps to strengthen the lean healthcare state of the art and to integrate theoretical-applied knowledge. For healthcare professionals, it might provide an overview of the key factors that can promote lean implementation.
Companies seek to improve service level, aiming to meet the most demanding customers that enable it survives in a complex and competitive marketplace. The article presents a study in a company of repair and maintenance of industrial equipment and instruments, located in Campos dos Goytacazes (RJ), aiming to identify the factors that influence the execution time of the operators' activities in the manometer calibration process. For this scope, the study of times and movements and statistical analyzes, such as Linear Regression and ANOVA, were applied. The survey revealed that operators who have completed their technical courses in mechanics perform the activities in standard time greater than those who have not yet completed and that working on board and being married do not change the execution time. It also revealed that employees of lower age and longer experience are preferable because of shorter operating times and that the age was statistically significant, revealing that the most appropriate age to have a shorter time is approximately 27 years.
Goal: this research aims to deploy TQM in the new customers area of an electricity distribution company, located in Campos dos Goytacazes (Rio de Janeiro), based on three management pillars: guidelines, processes and routine. Design / Methodology / Approach: the nature of this work is applied research, with a qualitative problem approach, characterized as exploratory, using case study as a technical procedure, with data collected between april and september of 2015. Results: the performed methodology allowed a reduction of both "orders after deadline" (12%) and "unproductive visits" (22%) indicators. Limitations of the investigation: the research presented limitations, first, because of the resistance of some employees during the tools implementation and second, the methodology was implemented only in a sector of the company. Practical implications: the study was based on indicators and targets already used by the company. It was proposed and implemented an anomalies analysis and tools such asthe PDCA cycle, Pareto and Ishikawa diagrams, 5W1H, and Standard Operating Procedures. Originality / Value: there is little research with emphasis on TQM, especially when referring to an analysis using three levels of management (guidelines, process and routine) in the Brazilian electricity sector.
Team formation is a key aspect of football, being able to bring sporting and financial results, but also susceptible to great risks. Considering that this problem involves subjective decisions, it also becomes subject to failures. The use of quantitative approach methodologies can overcome such aspects and offer better results for football clubs. In this context, a systematic review was carried out on Operations Research techniques for player selection and formation of football teams, demonstrating the main references and authors of the area. A search on the scientific bases Web of Knowledge, Scopus, and ScienceDirect was carried out during the month of January of 2018, analyzing a total of 1,637 articles. Of these, only 12 were selected for analysis. The research of Boon and Sierksma (2003) was identified as the main reference of the area, being referenced by four other authors. It is highlighted the low number of citations between the papers, as well as the lack of review articles like this one. All these aspects contribute to the relevance of this research, addressing a significant problem in one of the most popular sports in the world and unifying its main references.
The metrology area is responsible for measurement properties and is present in the market through services related to calibration, standardization, maintenance, measurement traceability, and certification. While there is a demand from metrology companies for efficient methods of managing the quality of their services and operations, lean culture encompasses the most important management techniques with applications in various segments. Considering the aspects that permeate these two areas, the question arises about a possible intersection between the demands of companies and metrology laboratories to remain competitive and certified in the market and benefits provided by lean culture. Thus, this paper performs a systematic review, according to the PRISMA protocol, in order to verify if there is an intersection between lean and metrology in the scientific literature. Through bibliometric and qualitative analyses, the research shows a gap of application with a lack of articles in this area, as well as a great potential of places and tools to be implemented.
The concept of Industry 4.0 is very recent and has not been fully consolidated, and, for this reason, comprehensive implementations by the industrial sector may not be prudent. Studies show that only fundamentals of Industry 4.0 do not guarantee characteristics such as quality, for example, in production processes. Thus, lean production concepts are probably being used together to cover deficiencies in Industry 4.0. In this work, a literature review is proposed that points out where lean production tools are being used in the production processes of Industry 4.0. Using the results of this search, an analysis of the most important lean production tools, which appear in the works, has been made. The analysis has shown what is being used, in terms of the lean tools, in the production processes of Industry 4.0, and what improvements are provided from these tools.
PurposeLean healthcare (LHC) applies lean philosophy in the healthcare sector to promote a culture of continuous improvement through the elimination of non-value-added activities. Studies on the subject can be classified as conceptual (theoretical) or analytical (applied). Therefore, this research compares bibliometric indicators between conceptual and analytical articles on LHC.Design/methodology/approachFor data collection, the PRISMA Protocol was employed, and 488 articles published from 2009 to 2021, indexed in the Scopus and WoS databases, were retrieved.FindingsThis study reveals how conceptual and analytical LHC studies are organized in terms of the most relevant journals, articles, institutions, countries, the total number of citations, collaboration networks (co-authorship, international collaboration network and institutional collaboration network) and main co-words.Originality/valueOnly four papers conducting bibliometric analysis on LHC studies were identified in the Scopus and Web of Science databases. In addition, none of these papers compared conceptual and analytical bibliometric indicators to reveal the evolution, organization and trends of each category. Therefore, this work is not only the first to make this comparison but also the first to analyze the collaboration between authors, institutions and countries in relation to studies on LHC. The analyses performed in this work allow one new possible understanding, by researchers and health professionals, of the literature behavior in this field of study.
