Leadership is a combination of managerial attitudes and behaviors that directly influence indi-vidual and organizational performance. This study aimed to design a model of the antecedents and consequences of leadership in the National Gas Company of Iran. Using a mixed-methods approach, the qualitative phase involved 18 experts with extensive academic and professional experience, including university lecturers and senior managers in organizational behavior and human resource management. The quantitative phase included 265 employees from the Kerman Gas Company, selected via stratified sampling. Data were collected through document reviews, expert interviews, and structured questionnaires. Analyses employed thematic analysis, structur-al-interpretive modeling, and structural equation modeling using NVIVO, SPSS, and Smart-PLS software. The findings identified 82 primary codes, 21 basic themes, and 8 organizing themes, encompassing factors such as participatory decision-making, internal (individual) influences, emphasis on organizational values, talent management, transparency in communication, em-ployee retention, organizational productivity and growth, and organizational justice. Structural equation modeling demonstrated high reliability (Cronbach's alpha > 0.7), favorable composite reliability, and strong convergent and divergent validity. The model's fit was validated, with par-ticipatory management identified as the primary driving force in enhancing organizational stabil-ity and performance. This study provides practical insights into the implementation of effective leadership practices, offering a framework to improve decision-making, foster employee en-gagement, and enhance organizational outcomes. The findings serve as a strategic tool for man-agers to promote a culture of inclusivity, transparency, and growth within the National Gas Company.
