  Lean process improvements are crucial for enhancing production efficiency. In my research, I examine the application of the DMAIC methodology to develop the MEP facility within the framework of lean Six Sigma. Highlighting the challenges of precast concrete production, my study details how lean management aids in efficient process design and measurement. Introducing lean Six Sigma methodology involves standardizing processes and ensuring their effective development, contributing to the facility's efficiency

  The philosophy and methods of six sigma process development have been applied successfully since mid1980s, and the application of the six sigma concept in non-production processes has increased significantly in the last decade. In this paper processes that can be characterized by learning curves are modeled. The quality of such processes can be analyzed on the basis of the six sigma concept. In this paper two back office processes are analyzed. The processes are built up of simple repeated steps and incorporate some interruptions. The application of the model allows the calculation of the maximally permitted number of interruptions in the process if the preliminary determined norm is to be kept.

  This paper deals with the development of a force measuring device to determine the opening force of different types of balancing clips. These elements can be used in the impellers of ventilators to rebalance the rotor. The measuring device contains a commercially available beam type load cell. The data processing is performed by Arduino Nano development platform with a 24-bit sigma delta A/D converter. The device is well applicable to determine the opening force of the clips in different opening distances.

  Development of the Science and practical application of the results created big changes in the nontradicional areas too. The „Health industry” was developed. The results of the physics, chemistry, biology and mikroelektronics etc. helped to develop some new methods of diagnosis, operation etc. The „money industry” was developed too. Our opinion is, that the most important cause of the economic crisis is a non regulated well of the „money industry”. The „knowledge industry” was developed too. The „knowledge industry” contains all level of teaching and Research + Development + Innovation. Our analyze shows that the Innovation is the most important factor of the economic Development of Society. The new scientific results created big changes in area of the Management. The „Management Science” was developed as an independent area. Some management specialists developed some management methods (eg. Value Analysis, Risk Management, TRIZ, Lean methods etc.) for efficient allocation of sources.
