Purpose: The main aim of the article is to present the results of research of entrepreneurs who maintain a certified quality management system in terms of leading factors supporting decisions of a preventive approach to management. Design/methodology/approach: Interview method conducted in manufacturing companies with an implemented and certified quality management system using CATI technique Findings: Research has shown that in large industrial enterprises the key stimulants of preventive actions are, above all, efficient information flow, technical and organizational order, as well as consistent pursuit of the goal. Smaller enterprises put the main emphasis on maintaining good relations with the environment, safety and ergonomics of work, as well as skillful selection of suppliers. Research limitations/implications: The authors of the paper see the need to continue research in the field of in-depth analysis of selected factors in relation to the effectiveness of the actions taken and the possibility of supporting information. Practical implications: Entrepreneurs with knowledge of key stimulants will make decisions more consciously and focused on a targeted analysis of data in order to search for relevant premises to prevent non-compliance. Originality/value: This paper concerns key factors influencing a preventive approach that can support decision-making. For the purposes of multicriteria decision-making processes, it is valuable to know the key stimuli characteristic of effective preventive actions. An additional value of the article is the showing of the factors with a differentiation by company size. This enables a more relevant focus of the research results.

The purpose of the paper is to investigate the factors impacting project success among personnel based on the example of the Yemeni oil and gas industry. The data was analyzed by hypothesis testing, Smart-PLS tool, SPSS and several statistical methods such as the Structural modelling, regression weights and T statistics and regression technique, utilized to comprehend the variables' dimensionality. The results showed that influential factors i.e. personnel (P), project schedule/plan (PSP), troubleshooting (TS) and technical tasks (TT) as well as the technological advancement (TA) have a statistically significant relationship with project success. It suggests that increasing the success rate of projects may be bilaterally beneficial to the project managers. Limitations and suggestions for future research were also mentioned.

Celem artykułu jest zbadanie czynników wpływających na sukces projektu wśród personelu na przykładzie jemeńskiego przemysłu naftowo-gazowego. Dane zostały przeanalizowane za pomocą testowania hipotez, narzędzia Smart-PLS, SPSS i kilku metod statystycznych, takich jak modelowanie strukturalne, wagi regresji oraz statystyki T i techniki regresji, wykorzystywane do zrozumienia wymiarowości zmiennych. Wyniki pokazały, że czynniki wpływające, tj. personel (P), harmonogram/plan projektu (PSP), rozwiązywanie problemów (TS) i zadania techniczne (TT) oraz zaawansowanie technologiczne (TA) mają statystycznie istotny związek z sukcesem projektu. Sugeruje to, że zwiększenie wskaźnika sukcesu projektów może być obustronnie korzystne dla kierowników projektów. Wspomniano również o ograniczeniach i sugestiach dotyczących przyszłych badań.

Given the high-power concentration of combustion engines used in military aviation, it is reasonable to measure the instantaneous surges in the sound pressure level. Therefore, a research question was raised regarding the differences in this level for various aircraft engines of the same type (F100-PW-229) to assess their size and statistical significance. The aim of the paper is to discuss the attempt to check the significant difference between the parameters of the acoustic level generated by the aircraft engines. The measurements were carried out for 32 engines of the F-16 Block 52+ multirole aircraft during takeoff process. The parameters of noise in the point system and in the octave distribution were subject to analysis. Statistical methods dedicated to assessing production stability, i.e. the Shewhart chart, were applied. The results of the analysis showed that the discrepancies generally do not exceed a value of +/− 3σ . Therefore, it can be concluded that the analogous results for F-16 noise are homogeneous. Thus, the Shewhart chart method proved useful for assessing the homogeneity of these measurements.
