2. Business and technological processes optimization in automotive manufacturing : continuous improvement through process capability, operational effectiveness, and return on investmentRobert Pavlin, Mirko Markič, Franci Pušavec, Aleksander Janeš, 2026, original scientific article Abstract: This study develops and empirically validates an integrated monitoring framework linking technological, operational, and financial performance indicators in automotive manufacturing. While process capability (Cpk), overall equipment effectiveness (OEE), and return on investment (ROI) are widely applied, their interrelationships are rarely examined within a unified empirical framework in real production environments. The proposed model is implemented within a business and technological processes monitoring system for the production of automotive daytime running lights (DRL), combining real-time measurement, automated data acquisition, and structured process optimization. A multi-phase implementation strategy enabled the transition from manual to fully automated monitoring, supported by more than 1,400 measurements collected across key technological operations in accordance with international standards. A longitudinal case study design was applied, and statistical analyses, including correlation and regression methods, were used to examine relationships between process capability, operational performance, and financial outcomes. The results show that systematic optimization increased equipment effectiveness from 78.36 % to 85.41 % and financial return from €2.9 million to €7.98 million, while achieving process capability levels above the required thresholds (Cpk > 2). A strong statistical relationship was identified between OEE and ROI, whereas the relationship between process capability Cpk and OEE was not statistically confirmed as a direct effect. The findings indicate that technological, operational, and financial indicators are interconnected but not strictly linear, highlighting the importance of integrated monitoring for understanding performance dynamics in manufacturing systems. The proposed framework provides an empirically grounded approach for linking process stability, operational efficiency, and financial outcomes, supporting performance evaluation and continuous improvement in automotive manufacturing.

3. Lean manufacturing and return on equity : evidence from Slovenian manufacturing firms using the DuPont modelSandi Povše, Mirko Markič, 2026, original scientific article Abstract: Lean manufacturing is widely recognized as an operational philosophy of process improvement; however, its relationship with financial performance remains relatively underexplored empirically. The purpose of this study is to examine the relationship between lean manufacturing and return on equity (ROE), and to link operational improvements with financial outcomes through the DuPont model. The research comprises a comparative financial analysis of a selected manufacturing company for the period 2019–2023, as well as a quantitative analysis of a sample of 240 Slovenian manufacturing enterprises. Descriptive statistical methods, correlation analysis, and linear regression with a composite lean maturity index were employed. The results indicate that ROE in the analyzed company increased from 4.74% to 11.99%, with growth primarily driven by improvements in net profit margin and process efficiency rather than by increased financial leverage. The empirical analysis demonstrates a statistically significant positive association between the level of lean maturity and ROE (β = 0.255; R² = 0.065; p < 0.001; N = 240). Although the explained variance is moderate, the findings indicate that lean maturity represents a statistically significant and managerially relevant determinant of financial performance within a multifactor business environment. The contribution of the study lies in the integration of the Lean approach with the DuPont model as an analytical bridge between production and financial functions, as well as in the empirical validation of this relationship within the Slovenian industrial context.

9. Ustvarjanje znanja za trajnostni razvoj visokošolskih ustanovMirko Markič, Tina Quéchon, 2026, published scientific conference contribution Abstract: Izobraževanje za trajnostni razvoj predstavlja enega izmed globalnih ciljev iz Agende Združenih narodov do leta 2030 ter vsebuje pridobivanje novih znanj in veščin. Management znanja pomeni ustvarjanje, pridobivanje, deljenje, hranjenje in uporabo znanja. V slovenskem visokošolskem prostoru ne obstaja teoretična ali empirična raziskava, v kateri bi avtorji celovito povezovali institucionalno transformacijo, ustvarjanje znanja in trajnostne prakse. Namen našega prispevka bo predstaviti ugotovitve iz pregleda dosedanjih 35 raziskav o treh navedenih konceptualnih dimenzijah, ki so prisotne v globalnem visokošolskem prostoru. Pregled smo opravili v javno dostopnih bazah podatkov s pomočjo metodologije PRIZMA. Izidi iz naše raziskave bodo imeli teoretične in praktične implikacije za managersko znanost ter stroko in bodo spodbujali snovanje nacionalne raziskovalne ter izobraževalne politike in strategije.
Keywords: institucionalna transformacija, management znanja, trajnostni razvoj, ustvarjanje znanja, visoko šolstvo
