Text in English / Global and South African business challenges necessitate an increased focus on the need for effective leadership. The leaders of South African public listed organisations need to investigate new business solutions to enhance and sustain organisational effectiveness. Public listed South African organisations on the Johannesburg Stock Exchange (JSE) were selected as the organisation type for this study. This study was motivated by the need for public listed South African organisations to explore organisational leadership as a means to assist in differentiating their organisations from competitors, thereby enhancing organisational competitiveness. The primary research objective of this study was to investigate and establish an organisational leadership brand concept model for public listed South African organisations. The discussion of the literature covered the global and South African business context, the concepts of the nature of organisational leadership, brand and organisational leadership brand, and emminated in an exploratory conceptualisation of organisational leadership brand for public listed South African organisations. The pragmatic paradigm was used as the foundation of this study. The study adopted an exploratory, sequential mixed methods research approach, combining a qualitative emphasis and supportive quantitative research approach to conduct the exploratory research. The qualitative findings proposed the concepts: the nature of organisational leadership and organisational leadership brand, including stakeholders and these concepts served as the basis for designing the quantitative survey questionnaire. The quantitative results indicated reliable questionnaire items, and based on the exploratory statistical analysis of the multivariate linear regression equation, described the organisational leadership brand (OLB) concept exploratory model with the best fit. An integration of the qualitative findings and quantitative results provided the empirical support to achieve the primary research objective. The OLB concept model integrates the concepts of organisational leadership and organisational leadership brand. The study contributed across the methodological, theoretical and practical domains as follows: the nature of organisational leadership for South African public listed organisations was conceptualised; the elements comprising the concept of OLB for public listed South African organisations was described; the OLB concept model for public listed South African organisations describes the development of organisational leadership brand equity through four levels of organisational leadership brand equity development; and the OLB concept model for public listed South African organisations may assist by providing guidance for the senior leadership of organisations in establishing organisational leadership brand equity. Furthermore, the study’s research approach provides support for the use of a mixed methods research approach in the study of organisational leadership within the pragmatic context of business organisations / Industrial & Organisational Psychology / D.
