What makes millennial leaders succeed in Indonesian companies? An integrated mixed-methods study

This study addresses the critical gap between millennials’ workforce dominance (65–95% across Indonesian sectors) and their underrepresentation in leadership positions, developing an empirically validated leadership development model for this demographic transition. The research aims to identify factors influencing millennial leadership quality and create actionable strategies for Indonesian organizations facing generational leadership shifts. Using a sequential mixed-methods approach, we conducted qualitative interviews with 14 senior executives across seven diverse companies, followed by quantitative validation through surveys of 312 respondents. Data collection employed semi-structured interviews and thematic analysis, complemented by Multiple Linear Regression analysis to test seven hypotheses regarding millennial leadership effectiveness. Results revealed four significant factors explaining 63.5% of variance in millennial leadership quality: organizational culture (β = 0.439), regular impact recognition (β = 0.257), technology advancement (β = 0.150), and feedback through coaching and mentoring (β = 0.122). Organizational culture emerged as the dominant driver, emphasizing inclusive, collaborative environments over individual-focused interventions. Challenging experiential learning, organizational purpose, and work-life balance showed no significant direct impact despite strong qualitative support. This research provides a contextually relevant framework addressing gaps in leadership literature for emerging economies, offering validated strategies for developing millennial leaders through cultural transformation and structured recognition systems.
