Abstract:

This study examines the role of leadership development in strengthening strategic management practice within multinational corporations, using Unilever as an illustrative case. As a global consumer-goods leader operating in more than 190 countries, Unilever confronts complex, fast-changing market volatility that demands agile, ethical, and digitally fluent leadership. The study adopts a mixed-methods design that combines a secondary qualitative synthesis of publicly available Unilever documentation and published leadership scholarship with a primary quantitative survey of 25 Unilever employees, administered using a 14-item, five-point Likert-scale instrument. This design directly addresses a central limitation of earlier drafts of this research, namely an over-reliance on two non-independent, author-produced academic studies as the sole evidentiary base. Descriptive statistics, reliability testing, and correlation analysis of the survey responses are triangulated against the secondary case evidence across five thematic domains: leadership development structure and strategic alignment, sustainability and purpose-driven leadership, digital transformation, cross-cultural and cross-functional collaboration, and innovation and stakeholders engagement. The findings of the study indicate that employees perceive sustainability leadership, cross-departmental collaboration, and cultural intelligence as comparative strengths (means above 4.0 on a five-point scale), while strategic alignments and digital-skills readiness are perceived less consistently (means of 3.52 and 3.80 respectively, with the widest dispersion in the dataset). Correlation and reliability analysis reveal only weak associations between individual items and the overall strategic-management outcome measure, which is interpreted critically as evidence that the instrument captures genuinely distinct sub-constructs rather than a single underlying attitude, and as a caution against treating leadership development as a uniform, undifferentiated intervention. The study contributes a replicable framework, including a Leadership Return-on-Investment (ROI) approach with illustrative key performance indicators, for other multinational corporations seeking to align leadership development with strategic outcomes.
