A proposta deste artigo é avaliar o sistema de medição em um estudo de caso utilizando a ferramenta Gage R&R, com o objetivo de descobrir a variação das medições, podendo ser por Repetibilidade e/ou Reprodutibilidade. Na ferramenta DMAIC utilizada no Seis Sigma, a etapa Medir é usualmente a mais complicada e demorada pela baixa qualidade dos sistemas de medições da maioria das empresas. Pretende-se uma revisão literária para melhor conhecimento do assunto, assim, a primeira etapa foi a criação de um procedimento para a empresa em estudo. Após a elaboração do procedimento, os colaboradores foram treinados e a gerência definiu as principais inspeções que afetam o produto para a realização do estudo. Em seguida, a ferramenta foi aplicada e cada saída foi analisada comprovando a presença de variações que poderiam não ser consideradas. Palavras-chave: Sistema de medição. DMAIC. Gage R&R. Abstract The proposal is to evaluate the measurement system in a case study using the tool Gage R & R in order to find the variation of the measurements may be for repeatability and / or reproducibility. The tool used in Six Sigma DMAIC, the Measure step is usually the most complicated and delayed by the poor quality of measurement systems of most companies. We performed a literature review to better knowledge of the subject, so the first step was to create a procedure for the company under study. Following completion of the procedure were trained employees and management identified key inspections that affect the product for the study. Then the tool was applied and each output was analyzed demonstrating the presence of variations that could not be considered. Keywords: Measurement System. DMAIC. Gage R&R.

Barriers And Challenges

Purpose Literature reviews are a pervasive aspect in research. An ever mounting field such as Lean Six Sigma requires a perpetual touch on the subject to accentuate insights that can be researched about. The purpose of this paper is to address the published literatures in the field of Lean Six Sigma through multiple criterion for an enhanced understanding of the subject matter through summarizing its current trends, uncovering existing literature gaps and revealing opportunities for future research in the field. Design/methodology/approach The literature review on Lean Six Sigma field spans around 17 years that includes peer-reviewed journals from management, business, engineering, healthcare, manufacturing, military among the many disciplines. The study uses a content analysis approach in which several dimensions of the literature were analysed: purpose or focus of study, years of publication, journal name or publications, methodologies, theories used, country of study, industry sub-sectors, active authors in the field, critical success factors, barriers and challenges and the most contribution of Lean Six Sigma papers by universities. Findings Eleven important findings from the analysis were summarized among them; the field of Lean Six Sigma had begun to grow significantly since the new millennium particularly after the 2004-2007 or 2008 period; standalone concepts of Lean and Six Sigma are highly researched compared to the integrated concepts; large proportion of perspective, conceptual and descriptive based studies; lack of empirical validity on the fusion between Lean and Six Sigma; lack of theoretical based studies, etc. Research limitations/implications The study is limited to 102 journals in commonly searched databases in the subject matter which produced 261 journal papers. This study seeks to broaden the summary of studies done under the keyword “Lean Six Sigma”. Originality/value The review analysis uses a content analysis approach in search of valuable gaps in existing research. The study found 261 papers from 102 journals that were published over the past seventeen years (2000-2016). This paper provides scholars, practitioners and managers with insights on the present trends and focus of Lean Six Sigma in addition to what else are lacking in the subject matter, which could pave the way for future research and practical endeavours.

Purpose The purpose of this paper is to provide a critical analysis of publications relating to the use of continuous improvement (CI) methodologies, such as Lean, Six Sigma and Lean Six Sigma over a 17-year period, to identify the themes and gaps, while informing the development of a future research agenda. Design/methodology/approach The systematic literature review identified 121 papers published between 2000 and 2017 from searches of over 1,400 peer-reviewed academic journals and also identified the application of Lean, Six Sigma and Lean Six Sigma across the public sector. Findings This research compares the scale and breadth of the public sector with the application of CI methodologies and finds that such application is unstructured and, in some areas, sporadic. The research identifies common themes and research gaps including areas such as lack of shared understanding of Lean, gaps in strategy development and leadership and an overfocus on tools alone. Research limitations/implications The methodology is focussed on the journals rated in the ABS Journal Guide 2015, which allowed manual searches for accuracy and relevance to the area of investigation. It is recognised that this may exclude some articles which have been published in other journals but allowed for a structured and detailed investigation. The research identifies some very clear gaps which can inform future research agendas. Practical implications The paper details the implications and challenges to the public sector, generally, and to executive leadership, specifically, and, in particular, covers the common issues and concerns, which in turn will assist public sector organisations in implementing, reviewing or refreshing their CI initiatives. Originality/value No similar work has been conducted and while some individual areas such as health and education have been the subject of more focus, this research explores the public sector as a whole and considers the patterns of research in that context.

Development Capability

Purpose The paper presents a process of development of the capacity of resources used in the improvement of an organization. The purpose of this paper is to determine the conditions in which the development of the improvement capacity is sustainable. Design/methodology/approach As the basis for the study, the following prerequisites have been adopted: potential effects of the use of resources in a process can be expressed by their capacity, which involves the productivity and volume of the resources; a model of sustainability of improvement is based on the procedure ABC and principle of continuous improvement; an improvement process involves two components: subject matter (eliminating problems) and methodical (learning how to eliminate problems during the execution of subject matter tasks) projects; the methodology of Six Sigma can be a reference model, which is studied to identify and interpret elements and relationships that are characteristic for the process of sustainable development. Findings There have been formulated a model of the process of developing the improvement capacity in which the subject matter and methodical tasks are coupled, a model of the Six Sigma process that refers to the features of the process of development of the improvement capacity and three principles for sustainable development of improvement capacity. Originality/value The principles refer to decisions on the improvement process made at basic (strategic, tactical and operational) levels of an organization.

The Subject

THE germ of that which follows came into being many years ago in the days of my youth as a university instructor and assistant professor. It was generated by the then quite outspoken attitude of colleagues in the “exact sciences”; the sciences of which the subject-matter can be exactly weighed and measured and the force of its movements mathematically demonstrated. They assured us that the study of languages and literature had little or nothing scientific about it because: “It had no domain of concrete fact in which to work.” Ergo, the scientific spirit was theirs by a stroke of “efficacious grace” as it were. Ours was at best only a kind of “sufficient grace,” pleasant and even necessary to have, but which could, by no means ensure a reception among the elected.

Orbit Computation

In this paper an orbit computation program for artificial satellites is presented. This program is operational and it has already been used to compute the orbits of several satellites.After an introductory discussion on the subject of artificial satellite orbit computations, the features of this program are thoroughly explained. In order to achieve the representation of the orbital elements over short intervals of time a drag-free perturbation theory coupled with a differential correction procedure is used, while the long range behavior is obtained empirically. The empirical treatment of the non-gravitational effects upon the satellite motion seems to be very satisfactory. Numerical analysis procedures supporting this treatment and experience gained in using our program are also objects of discussion.

Rule: I'd like at this point to bring up the subject of cables and wireways around the telescope. We've touched upon this twice during previous sessions: the cable wrap up problem, the communications problem, and data multiplexing problem. I think we'll ask Bill Baustian if he will give us a brief run down on what the electrical run problems are, besides doubling the system every year.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

The growth of Ag films deposited on various substrate materials such as MoS2, mica, graphite, and MgO has been investigated extensively using the in situ electron microscopy technique. The three stages of film growth, namely, the nucleation, growth of islands followed by liquid-like coalescence have been observed in both the vacuum vapor deposited and ion beam sputtered thin films. The mechanisms of nucleation and growth of silver films formed by ion beam sputtering on the (111) plane of silicon comprise the subject of this paper. A novel mode of epitaxial growth is observed to that seen previously.The experimental arrangement for the present study is the same as previous experiments, and the preparation procedure for obtaining thin silicon substrate is presented in a separate paper.
