Before mass production of individual components industries may assess its capability to produce it according to specifications. This capability assessment is a common requirement in the automotive ...sector. This work shows a case study, providing an in-depth analysis, on a critical component and finds evidence of process degradation over two years of production, quantified through capability analysis. At pre-production, it was concluded that the process was capable and, thus, no statistical process control was done during its production. Over the months no defective units were detected but then its level began to increase and it was apparent that process variability had increased and the process was no longer capable. Process improvement activities were developed using known quality tools and methodologies. This work shows how the control plan initially defined became obsolete and discusses the need to periodically review quality control mechanisms.
The results of the development of a modified quality function deployment (QFD) method, obtained for the first time to improve the product quality planning process in the metal cutting of laser ...technologies confirming the dynamics of open innovation, are presented. When using new marketing technologies, the requirements of consumers are established; a factorial model of customer satisfaction was determined with after an assessment by expert methods, their wishes were transformed into indicators of product quality, and its concept was developed. Product quality is enhanced by optimizing project specifications. The method of functional cost analysis (FCA) was applied for the manufacturing processes, which made it possible to reduce the costs of their implementation. New methods of product quality control were applied. The developed planning process is described by a sequence diagram, an algorithm, and a responsibility matrix. The research used search methods including Internet resources required for open innovation, namely functional modeling methods (IDEF) and the method of advanced product quality planning (APQP). The results of the achieved advantages of open innovation (reduction in research and development costs, implementation of the principles of total quality management (TQM), customer orientation, process approach, improvement) are recommended for further application both at the enterprise and in the metalworking of mechanical engineering. The practical significance of the results of this work is the reduction in internal and external failures by 12%; reduction in time for new product development by 9%; reduction in costs for online resources by 11% and quality control during production by 7%; reduction in labor costs for process management by 25%; and the stability of the process, which improved by 25%.
Background:
In 2012, the Health Resources and Services Administration and the United Network for Organ Sharing launched the “Electronic Tracking and Transportation” (ETT) project, in response to ...“labeling and packaging issues” being a frequently reported safety incident. This article describes an improvement project conducted as part of this United Network for Organ Sharing project.
Methods:
An interdisciplinary team conducted a Process Failure Modes and Effects Analysis, laboratory simulations of organ labeling during procurement, and a heuristic evaluation of a label software application to inform the design of TransNet, a system that uses barcode technology at the point of organ recovery. A total of 42 clinicians and staff from 10 organ procurement organizations and 2 transplant centers in the United States participated.
Processes Addressed:
Key features of the redesigned labeling system include independent, double entry of label information into the software application, a machine-readable barcode on each organ’s label, and a handheld printer for at “point of use” label printing.
Outcomes:
The new labeling system, TransNet, has become mandatory since June 2017. A survey conducted on early adopters (N = 11), after 1 year of use, indicates the process is safer and more efficient.
Implications for Practice:
The findings from this study suggest that the application of quality planning methods, common in other industries, when redesigning a health-care process, are valuable and revelatory and should be adopted more extensively. Future evaluation of TransNet effectiveness to reduce safety incidents is critical.

This research was conducted on the implementation of the national exam in academic ...year 2007/2008 Jakarta using survey questionnaire methods in five areas of Jakarta. Questionnaires distributed to students, teachers and supervisors of national examinations. Data were analyzed based on Six Sigma, which has four areas which include quality planning, quality control, quality assurance and quality improvement. result that all schools have generally been preparing themselves before the national exams. Each school has a special program for students to national exam. The program, among others, provide additional educational materials outside lesson time, an extra studying on Saturday and Sunday. To control the quality of each school formed a special committee chaired by the principal. Because the national exam and the estuary is an important activity of all school activities that have been fostering student for six semesters. National exam to measure the success of the school so that the quality coaching to the students to become primary. If you need to be improved in order to be better. From the students, all students are required to follow all the final semester of the program established by school. Therefore, all students are ready for facing a national exam. Graduation rate of students on national exams students did not disappoint, generally in accordance with the expectations of students, parents, teachers and schools. ABSTRAKTujuan penulisan artikel ini dimaksudkan untuk membahas hasil penelitian tentang penerapan Six Sigma pada ujian nasional SMU di Jakarta.

Ujian nasional menjadi tolok ukur keberhasilan sekolah, sehingga kualitas pembinaan kepada peserta didik menjadi prioritas.
The minimization of negative externalities is a key aspect in the development of a circular and sustainable economic model. At the local scale, especially in urban areas, externalities are generated ...by the adverse impacts of air pollution on human health. Local air quality policies and plans often lack of considerations and instruments for the quantification and evaluation of external health costs. Support for decision-makers is needed, in particular during the implementation stage of air quality plans. Modelling tools based on the impact pathway approach can provide such support. In this paper, the implementation of health impacts and externalities analysis in air quality planning is evaluated. The state of the art in European member states is reported, considering whether and how health effects have been included in the planning schemes. The air quality plan of the Piemonte region in Italy is then considered. A case study is analyzed to evaluate a plan action, i.e., the development of the district heating system in the city of Turin. The DIATI (Dipartimento di Ingegneria dell’Ambiente, del Territorio e delle Infrastrutture) Dispersion and Externalities Model (DIDEM model) is applied to detect the scenario with the highest external cost reduction. This methodology results are extensible and adaptable to other actions and measures, as well as other local policies in Europe. The use of health externalities should be encouraged and integrated into the present methodology supporting air quality planning. Efforts should be addressed to quantify and minimize the overall uncertainty of the process.
The project is defined as an ensemble coordinated by some activities accomplished in order to reach a well determined purpose, namely the project defines a process. Quality management in projects ...includes the processes necessary for providing the fact that the project satisfies the necessities it had been accomplished for. The settlement of the main (strategic) objective of the project and of the lower objectives together with the establishment of the methods by means of which these objectives are reached represent the quality planning in projects.
Regional and local authorities have the obligation to design air quality plans and assess their impacts when concentration levels exceed the limit values. Because these limit values cover both short- ...(day) and long-term (year) effects, air quality plans also follow these two formats. In this work, we propose a methodology to analyze modeled air quality forecast results, looking at emission reduction for different sectors (residential, transport, agriculture, etc.) with the aim of supporting policy makers in assessing the impact of short-term action plans. Regarding PM

, results highlight the diversity of responses across European cities, in terms of magnitude and type that raises the necessity of designing area-specific air quality plans. Action plans extended from 1 to 3 days (i.e., emissions reductions applied for 24 and 72 h, respectively) point to the added value of trans-city coordinated actions. The largest benefits are seen in central Europe (Vienna, Prague) while major cities (e.g., Paris) already solve a large part of the problem on their own. Eastern Europe would particularly benefit from plans based on emission reduction in the residential sectors; while in northern cities, agriculture seems to be the key sector on which to focus attention. Transport is playing a key role in most cities whereas the impact of industry is limited to a few cities in south-eastern Europe. For NO

, short-term action plans focusing on traffic emission reductions are efficient in all cities. This is due to the local character of this type of pollution. It is important, however, to stress that these results remain dependent on the selected months available for this study.
Process and quality planning are prerequisites for the production of qualified products at competitive cost. Today´s document-based work methods are not effective as valuable time is spent on ...document creation and document management instead of being spent on innovation and process improvements. Information duplication is an inevitable consequence with current document-based work methods where the same information is described in different ways, at many places, across many different documents. This paper presents a model-driven approach where vital manufacturing information is described once, at one place, and in one way, enabling improved work methods for cross-organizational process and quality planning.
