and the 1980s ( Foley, 2004 ). One of the most influential quality movements during this era was the total quality management (TQM), which again owes its origin and conceptual developments to Japan ( Cole, 1998 ; Esaki, 2016 ; Juran, 1995). TQM eliminated the weaknesses of previous qualityimprovement techniques, which makes it an efficient quality management tool. TQM is an integrated approach that stresses the top-down approach, staff engagement in the process, evidence-based decision-making and the consideration of customer requirements ( Tobin, 1990 ).

The National Quality Programme of the Slovak Republic for 2017-2021 strongly emphasises the primary objectives and priorities of the Quality Improvement Strategy. This should be one of the main priorities of the Slovak Government in the upcoming period. The Quality Improvement Strategy should, in general, lead to an improvement in the quality of life. The aim of the paper is to point out the opportunities for improvement by applying indicators aimed at defining the excellence of organisations within the national economy of the Slovak Republic.
This paper presents our empirical observations related to the evolution of a large automated test system. The system observed is used in the industry as a test tool for complex telecommunication systems, itself consisting of more than one million lines of source code. This study evaluates how different changes during the development have changed the number of observed Code Smells in the test system. We have monitored the development of the test scripts and measured the code quality characteristics over a five years period.
The observations show that the introduction of continuous integration, the existence of tool support for quality improvements in itself, changing the development methodologies (from waterfall to agile), changing technical and line management structure and personnel caused no measurable change in the trends of the observed Code Smells. Internal quality improvements were achieved mainly by individuals intrinsic motivation. Our measurements show similarities with earlier results on software systems evolutions presented by Lehman.
Mathematical models were derived that describe the variability of ventilation and pressure drop as functions of cigarette design specifications and the variabilities of cigarette components. These models and the graphical isovariation contour representation have several important potential applications for quality control and improvement. For example, the models can be used in cigarette performance studies to determine the relative contributions of each source of variability and to identify the largest source of variability. The models can be used in quality improvement to target programs for maximum effectiveness and to set realistic goals for quality improvement. The quantitative variability values that the models produce can also be used to establish acceptance limits for the variabilities of the cigarette components which control ventilation and pressure drop variability within specified limits. These applications and the insight into the causes of variability that these models can provide should make them a valuable tool for improving the uniformity of cigarette performance.
The architectural innovations are becoming more and more important in the economic and social development and in the quality improvement of people’s lives. Sometimes, however, the implementation of innovative projects can lead to negative consequences. The development of any innovation should be based on a comprehensive analysis of their implementation’s consequences. Therefore, developing a responsible of the future architects’ attitude to innovations is extremely important for achieving a qualitatively new level of training of future architects to ensure sustainable development. This article presents the results of a research that investigated the social values of future architects and their attitude towards innovation.

Reliability is a key feature in engineering systems and might be improved by using preventive methods, which allows for identification potential failures and establishing cause-and-effect relationships in consistent and systematic way. One of the popular quality improvement method is FMEA (Failure Modes and Effects Analysis). An application of matrix FMEA analysis method on example of flow control valve has been presented and discussed in the work. Presented example shows also a different ways of evaluating failures and theirs influence on analysis results.
Penn State Hazleton has recently developed and implemented a new Engineering program with a focus on energy efficiency and energy sustainability. To accelerate the implementation cycle of the program, it was necessary to very rapidly create and establish the components of an ecosystem needed for the Engineering program to prosper and grow. This paper describes the individual components of the ecosystem as well as the methods used to establish them. The paper also discusses the different initiatives to increase enrollment as well as placement rates for graduates. Continuous quality improvement procedure applied to maintain the quality of the program is also being discussed.

Final inspection represents the last inspection operation of production line before the product reaches a customer. If nonconformities are not detected within the production process, final inspection has to ensure their detection. This contribution focuses on the final inspection results of the manufacturing process of automobile’s front seats. The outputs of final inspection are prepared by means of quality management tools (Pareto analysis). Inspection items, their changes, remedies and precautions leading to seat quality improvement are defined. The evaluation of final inspection for the following period confirms the improvement of the manufacturing process or control quality for selected inspection items.
