In today’s competitive global environment it is vital for businesses to continuously outperform their competitors, making each business more and more dependent upon product quality and the ability to adjust rapidly to change. To survive, businesses more and more depend on the creativity, initiative and problem-solving abilities of their employees. The research in this treatise will focus on the components of a high performance organisation, when assessing the international high performance strategy of Company A, developed by top management. The implementation of Company A’s strategy relies on how well the organisation fosters an environment which is conducive to high performance. At this stage it is not clear if the chosen strategy will succeed and direct the organisation towards sustainable high performance in the long run. Hence, the research question, which is the crux of this study, is to assess the effectiveness of Company A’s international high performance strategy in creating a sustainable high performance organisation in the long run. To achieve the primary objective of this research study, the researcher compared various prominent models of high performance organisations with one another. Despite the limitations, the researcher believes that the significance of De Waal’s model is that he managed to identify the factors involved in creating a high performance organisation. Based on the quantitative and qualitative comparisons, the researcher decided to use the research conducted by De Waal as the framework for the basis of this study. The Delphi Technique was used to identify the effectiveness of the strategy through a consensus seeking and commitment building process. Contrary to expectations, the empirical results indicated that Company A’s strategy does clearly indicate a high percentage of effectiveness. Although it definitely indicates that there is still a long road ahead of Company A to reach ultimate sustainable high performance, it definitely is on the right track. The research highlighted a few areas of concern, but with continuous adjustment and alignment of their strategy Company A would have a solid framework to work towards high performance in the long run.
