Michael Porter developed the Porter Diamond, also known as the Diamond Model, in 1990 in his book "The Competitive Advantage of Nations". The four determinants of Porter's diamond must operate as a system rather than individually. It provides answers to the question “Why does a nation achieve international success in a particular industry?” (Porter, 1998:71). Despite the universal application of Porter's diamond structure, many critics argue that the model is flawed. This essay aims to discuss the various criticisms leveled at the diamond network. First, an overview of the Porter's Diamond model will be provided. Subsequently, attention will focus on the numerous criticisms leveled at the model. Many, for example, have criticized the failure to consider government influence and the role of chance in the nation. Some also criticize the inadequacy of the regulatory framework for small economies, while others comment on the lack of historical perspective of the regulatory framework and, finally, the neglect of national culture in the regulatory framework. Porter's Diamond Model The Diamond Model (figure 1) outlines the "four general attributes of a nation that shape the environment in which local businesses compete that promote or impede the creation of competitive advantage" (Porter, 1998:71 ) Helps understand the nation's competitive position in global competition. The four determinants of national advantage are 1) factor conditions, 2) demand conditions, 3) related and supporting industries, and 4) firm strategy, structure, and rivalry.
