The Positive And Criticisms Of Porter's Theory

Porter has identified five (5) competitive forces that shape every industry and every market. The forces determine the intensity of competition and hence the profitability and attractiveness of an industry. Based on the information derived from this analysis, management can decide how to influence or to exploit particular characteristics of this industry.

Hill (2008) describes Michael Porter’s “Competitive Advantage of Nations Theory of posits that within specific industries, clusters of expertise result from highly competitive national environments” (p. 616). Michael Porter created the theory of competitive advantage when he began to realize the economic reality could no longer be explained based on the comparative advantage theory only (Laurentiu, n.d.). The competitive advantage theory is based on several determinants:

The intensity of rivalry, which is the most obvious of the five forces in an industry, helps determine the extent to which the value created by an industry will be dissipated through head-to-head competition. The most valuable contribution of Porter's “five forces” framework in this issue may be its suggestion that rivalry, while important, is only one of several forces that determine industry attractiveness.

Porter’s model aims to enable managers not only to understand their industry environment but also to shape their firm’s strategy. The five competitive forces are threat of entry, power of suppliers, power of buyers, threat of substitutes, and rivalry among existing competitors. “As a rule of thumb, the stronger the five forces, the lower the industry’s profit potential- making the industry less attractive to competitors. The weaker the five forces, the greater the industry’s profit potential – making the industry more attractive” (Rothaermel, 2013, p. 65). It is recommended that managers position their company in an industry in such a way that relaxes the constraints of strong forces and

The term competitiveness defines the ability of a region to export more than its imports while including all “terms of trade” to reflect government legislation and import barriers. In other words, according to the world competitiveness report, competitiveness is “… the ability to design, produce, and market goods and services, the price and non- price characteristics of which form a more attractive package than those of competitors.” (Pg3.) Each nation has different competitiveness level, which relies on multitude factors such as; raw materials, innovative technologies, energy prices, the type of economy, legislations, and the exchange rate fluctuations. Nevertheless, the prosperity of countries depends on the nation’s competitiveness status.

2. How Porter's Five Forces of Competition impact the company Porter set out his famous Five Forces model in chapter 1 of his 1980 Competitive Strategy: Techniques for Analyzing Industries and Competitors, which has now become the dominant paradigm for the "Structural Analysis of Industries." The model places supply chain forces on the horizontal access and market structure vertically above and below industry competition, which they all point to as the center of potential profitability (Hitt, Ireland and Hoskisson,

On the other hand, the criticisms of Porter’s theory vary widely from doubts on his theory’s originality (Dunning, 1993; Grant, 1991; Rugman and D’Cruz, 1993) to the over-reliance on global export shares as the measure of global competitiveness (Cartwright, 1993; Grant, 1991; Rugman and D’Cruz, 1993). Porter’s methodology was also denounced by several academics, which will be discussed below (Dunning, 1993; Rugman and D’Cruz, 1993; Rugman and

“Porter’s five forces”: Introduction. “Porter’s five forces” is widely applied in today’s business world. Harvard Professor Michael E. Porter’s first HBR article “How competitive forces shape strategy” was published in 1979. It became revolutionary in the field of strategy. Porter’s subsequent work has brought big changes to the study of competitive strategy for corporations, regions, and nations. With assistance from his colleagues from Harvard Business School, Porter continues to update and extend his classic work, providing practical guidance for

In the article “The Competitive Advantage of Nations” Michael Porter describes a diamond shaped relationship of forces that define a country’s potential for being competitive in a specified industry. The four points on the diamond representing the different forces are: factor conditions; demand conditions; firm strategy, structure and rivalry; and related and supporting industries. According to Porter, the four points apply pressure to each other resulting in a national

It is undeniable that strategies of today’s organization lead to manage for Globalization because the world is becoming global market. Concerning the relevance for Today’s Business, it is questionable: Are Porter’s Five Competitive forces still applicable? Dälken (2014) argued that the question to what extent digitalization, globalization and deregulation affect Porter’s Five Competitive Forces can be answered as follows: Since Porter’s Five Forces relies on the principals of microeconomics; the challenge of the credibility of the model is limited. The mentioned three forces make network unstable, more extensive, and more dynamic.

51]. The model suggests a successful businesses strategy to wart-off competition by careful application of an “environmental analysis”. The Porter model proposes five elemental strategic defenses against five potential forces: threat of new entrants, rivalry among competitive firms, bargaining power of suppliers, bargaining power of buyers, and the threat of substitution products.

Successful use of the Porter Model Analysis includes identifying the sources of competition, the strength and likelihood of that competition existing, and strategic recommendations for the action a company should take to develop barriers to the various forms of competition (Prahalad and Gary, 1990). With the realization about intensity and power of competitive forces, organizations can develop options to influence them in a way that improves their own competitive position. The result could be a new strategic option, e.g. a new positioning; differentiation for competitive products of strategic partnerships.

The manner in which firms are able to compete is most commonly categorized by implementing Michael Porter’s strategic typologies. Porter’s strategic theory has been the most widely accepted strategic approach used by fellow academics (Kim and Lim 1988; Bordean et al 2010). Porter proposed three generic strategies namely: cost leadership, differentiation and focus strategy. Warszawski (1996) later introduced a competitive strategy

Michael E. Porter, associate professor published the article titled “How Competitive Forces shape Strategy” in Harvard Business Review in 1979. This article is retitled as “The Five Competitive Forces That Shape Strategy” and published in Harvard Business Review in 2008. Michael E. Porter developed the model of Five Competitive Forces which is defined as “Competitive Strategy – Techniques for Analyzing Industries and Competitors”. It has become a main device for analyzing an organizations structure in strategic practices.

Any country should use porter diamond theory of national advantage. It's designed to help understand the competitive advantage nations. It suggests that the national home base of any organizations are playing a supportive role in shaping the size or scoop to which it is likely to achieve advantage on a global scale. This home base provides basic factors, which support organizations from building advantages in international competition. Porter classifies four determinants: Factor Condition, Diamond Condition, Relatives & supporting and Structure, strategy & Rivalry. Egypt government acts to catalysts to improve Egypt position in a globally competitive economic environment. They found that they can create new factors such as skilled labor and high technology (Porter M., 1990). Porter's diamond model suggests threat there are inherent reasons why some nations are more competitive than others on an international market. Another factor that influence in competitive advantages such as the policies that put by government. One of the most influencer policies is (FDI) Foreign direct investment
