| Abstract (English): |
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.

| Abstract (Slovenian): |
Ta študija razvija in empirično potrjuje integriran okvir za spremljanje procesov v avtomobilski proizvodnji, ki povezuje kazalnike tehnološke, operativne in finančne uspešnosti. Čeprav se zmogljivost procesa (Cpk), splošna učinkovitost opreme (OEE) in donosnost naložbe (ROI) pogosto uporabljajo, se njihove medsebojne povezave redko preučujejo v enotnem empiričnem okviru v realnih proizvodnih okoljih. Predlagani model je implementiran v sistemu za spremljanje poslovnih in tehnoloških procesov za proizvodnjo avtomobilskih dnevnih luči (DRL), ki združuje meritve v realnem času, avtomatizirano zajemanje podatkov in strukturirano optimizacijo procesov. Večfazna strategija implementacije je omogočila prehod iz ročnega v popolnoma avtomatizirano spremljanje, podprto z več kot 1400 meritvami, zbranimi v ključnih tehnoloških operacijah v skladu z mednarodnimi standardi. Uporabljena je bila longitudinalna zasnova študije primera, statistične analize, vključno s korelacijskimi in regresijskimi metodami, ki so bile uporabljene za preučitev razmerij med zmogljivostjo procesa, operativno učinkovitostjo in finančnimi rezultati. Rezultati kažejo, da je sistematična optimizacija povečala učinkovitost opreme s 78,36 % na 85,41 % in finančni donos z 2,9 milijona EUR na 7,98 milijona EUR, hkrati pa dosegla ravni zmogljivosti procesa nad zahtevanim pragom (Cpk > 2). Ugotovljena je bila signifikantna statistična povezava med OEE in ROI, medtem ko povezava med zmogljivostjo procesa Cpk in OEE ni bila statistično potrjena kot neposreden učinek. Ugotovitve kažejo, da so tehnološki, operativni in finančni kazalniki medsebojno povezani, vendar ne strogo linearni, kar poudarja pomen integriranega spremljanja za razumevanje dinamike učinkovitosti proizvodnih sistemov. Predlagani okvir zagotavlja empirično utemeljen pristop za povezovanje stabilnosti procesov, operativne učinkovitosti in finančnih rezultatov, ki podpira vrednotenje učinkovitosti in nenehno izboljševanje v avtomobilski proizvodnji.
