The book

The book ‘Cultural Confluence in Organizational change: a Portuguese venture in Angola’ presents an inspirational case study. It’s the story of Vasco Silva, a Portuguese businessman who established a business in Luanda, Angola. After four years of growth, Silva encounters a culture shock due to a spontaneous strike by the employees. He embarks on a deep cultural exploration and initiates an organizational change project. Together with the employees they transform the structure and the culture of the company and both Portuguese/western and Angolese concept of organization and leadership find their place. Consequently, Alette Vonk has collaborated with Silva, interviewed managers and employees and she has put the whole case in its historic as well as scientific context.

African Management Philosophy

Scientifically, the work contributes to the discourse in African management philosophy and responds to the demand for descriptive accounts of hybrid case studies of confluencing cultures. Scholars can utilize this case study to explore contemporary traditional African notions, demonstrating the performative characteristics of local leadership forms within business environments, and the flexibility for adaptation from both Angolan and Portuguese perspectives.

“An inspiring study on community building, shared values and transformative cultures in an African society.” (Dr. Michael Onyebuchi Eze, Lecturer African Philosophy, Leiden University).

“An invaluable guide for international leaders, providing insights into crafting novel management approaches based on a fusion of values.” (Manuel Quinaz, CEO at upK, SA).
