Thesis (MBA)--Stellenbosch University, 2008. / ENGLISH ABSTACT: The research seeks to investigate the progress of an indigenous group of companies in the advertising industry in Nigeria, in its bid to transform from unsustainable organisational practices to more sustainable and progressive practices that promote increased operational efficiency and organisational performance. The study made use of the Beehive Survey of High Performance Organisation TM and the Evolution to Excellence Framework (EEF), tools that were used by permission of the owners, The Village of Leaders Consulting, as well as interviews with staff of the company. The research objectives were firstly, to identify positive and negative influences on organisational culture change, secondly, to assist the subject company in identifying necessary steps to take in its bid to become world class and finally, to test the questionnaire model, the Beehive Survey, in an environment other than South Africa where it had been extensively used. The research further aimed to identify how far Nigerian companies had been able to achieve their bid to become truly world class with sustainable organisational practices, what type of leadership and cultural challenges they might face and what they needed to do to overcome these challenges. The major findings of the research were that indigenous companies need to reduce authoritative hierarchy and control, increase participation and interaction at all levels, increase transparency and information dissemination and clearly define the organisational vision and get the buy-in of all stakeholders.
