Minimizing sla time using six sigma dmaic method in a multinational company
No full textText in English ; Abstract: English and TurkishIncludes bibliographical references (leaves 39-42)xi, 43 leavesToday, the sectors are affected by the rapidly changing economic conditions. For this reason, service industries face global competition. The biggest problems of these industries are decreasing profit margins and high quality service demand. In today's economy, the sales price is mostly determined by the market, not by businesses. For this reason, businesses that carries out their processes effectively and efficiently can compete in today's economic conditions. Companies try to implement various strategies and innovations to improve their service quality processes. The first coming to mind and the most powerful philosophy for process development is Six Sigma. The aim of Six Sigma is to reduce cost and waste, to provide high quality service, and increase efficiency. Development methods were compared and as a result, DMAIC was chosen for the project. DMAIC is one of Six Sigma's most effective methods. Applying DMAIC is a good option for the development of the process, as the cause of the errors is not clearly visible in the processes. It is also a business strategy that helps to meet customer needs and expectations. Therefore, the Six Sigma DMAIC methodology has been applied to increase the quality of service provided to internal and external customers, to reduce time wasting and to increase the efficiency of the process. The steps of the implemented project are also explained in this thesis. In the study, Six Sigma is generally mentioned firstly and then DMAIC method and its steps are explained. Then, the phases in the implemented project are explained. The applied techniques in the five phases of the DMAIC project are included. The project has been implemented in an international company from the service sector to develop processes and improve service quality. The team to which the project is implemented receives extensive demand during the day. The time of meeting each request is calculated and the global target is four hours on average. Team performance can be calculated by drawing reports over a global system used by the company. The initial measurement shows that the average turning speed is seventeen hours. As a result, with the implementation of the DMAIC project, the average turning speed is reduced to two hours.Geliştirme metotları karşılaştırılmış ve sonucunda proje için DMAIC seçilmiştir. DMAIC, Altı Sigma'nın en etkili metotlarından biridir. Süreçlerde hataların nedeninin açık bir şekilde görünmemesi sebebiyle ve sürecin geliştirilmesi için DMAIC uygulamak iyi bir seçenektir. Aynı zamanda, müşteri ihtiyaç ve beklentilerini karşılamaya yardımcı olan bir iş stratejisidir. Bu nedenle, iç ve dış müşteriye verilen hizmetin kalitesinin artırmak, zaman israfını azaltmak ve sürecin verimini artırmak için Altı Sigma DMAIC metodolojisi uygulanmıştır. Bu tezde de uygulanan projenin adımları anlatılmıştır. Yapılan çalışmada ilk olarak Altı Sigma'dan genel olarak bahsedilmiş sonrasında ise DMAIC metodu ve adımları anlatılmıştır. Daha sonra uygulanan projedeki adımlar anlatılmıştır. DMAIC projesinin beş adımında uygulanan tekniklere yer verilmiştir. Proje hizmet sektöründen uluslararası bir firmada süreç geliştirmek ve hizmet kalitesini artırmak adına uygulanmıştır. Projenin uygulandığı ekip gün içerisinde yoğun olarak talep almaktadır. Her talebin karşılanma süresi hesaplanmakta olup küresel hedef ortalama dört saatir. Ekip performansı şirketin kullanmış olduğu global bir sistem üzerinden rapor çekerek hesaplanabilmektedir. Başlangıçtaki ölçüm ortalama dönüş hızının on yedi saat olduğunu göstermektedir. Sonuç olarak, DMAIC projesinin uygulanması ile ortalama dönüş hızı iki saate düşürülmüştür.SIX SIGMADefination of Six SigmaHistory of Six SigmaMethods ComparisonKaizenJidokaBusiness Process ReengineeringValue Stream TransformationSix Sigma in Service IndustrySIX SIGMA METHODOLOGY – DMAICDMAIC PhasesDefineMeasureAnalyseImproveControlReason to Chose DMAIC MethodDMAIC RolesExecutiveChampionProcess OwnerMaster Black BeltBlack BeltGreen BeltYellow BeltDMAIC ToolsHistogramFlow ChartsBrainstormingPareto DiagramSTUDY IN COMPANY AFirst PhaseProject CharterScopeVoC to CtC MatrixSecond PhaseThird PhaseFishbone TechniqueFourth PhaseEffort – Benefit MatrixFifth Phas
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
