The Sustainability of the Competitive Advantage

"A firm is said to have a competitive benefit when it's putting into action a value creating strategy not all together being put in place by any current or potential competition"

The competitive advantage, a concept presented by Michael Porter in 1985 has become one of the key concepts in management science today. Within the last 25 years, a big body of books engaged in analyzing how organisations can perform and, moreover, sustain a competitive benefit (Pralahad and Hammel (1990), Barney (1991), Peteraf (1993), Hall (1993) etc. ). During this process, two different perspectives or 'institutions of thought' surfaced. The first approach is based on the internal environment i. e. the fundamental characteristics of an company, in conditions of advantages and weaknesses determine a firm's potential to contend. This perspective is called the resource established view and was presented by Jay Barney (1991). The next approach is an organization's competitive capability will depend on more on the external environment and industry appeal. This perspective is known as the market structured view and was largely induced by Porter. Amount 1. 1 below schematically illustrates the essential difference between the two 'academic institutions of thought'.

Figure 1: A schematic illustration of the essential difference between the source- and market centered view. The source based mostly view argues a competitive advantage depends on an organisations specific resources and capabilities. The market founded view argues that the source of your competitive advantage sits within the competitive environment that characterizes its external product market.

This document is going to check out both perspectives in relation to achieving a ecological competitive. In the first section, the market established view of the firm is examined. In the second section, the source established view is examined. Finally, section 3 will compare both perspectives with regards to achieving a sustained competitive advantage in terms of these feasibility.

The Market Structured View of the Firm

The market centered view argues that the success of an company is not dependant on its inside characteristics, but is determined by the environment it works in. Hence, the company is undoubtedly a 'black package' and the opportunities for a sustained competitive advantage rest within the industry structure. Industry here refers to a group of firms producing a similar good or service. The underlying assumptions of the market centered view are that resources are homogenous and flawlessly mobile.

The theory of the market based view comes from Mason and Bain (1950) who web page link the composition of a business to a firm's success in the so-called Structure-Conduct-Performance-Paradigma. They dispute that the key factors for the success of an company are entry barriers, amount of players on the market as well as the elasticity of demand. In 1980, Michael Porter further developed this idea in his publication 'the competitive edge', which is one of the cornerstone literatures in management science today. In his work, Porter introduces a construction of so-called 'five forces', that determine the rivalry within an industry, as well as three 'generic strategies' that organisations can adopt to reach your goals.

In his 'five causes' framework, Porter asserts that four main motorists on the market framework determine the elegance of, as well as the competitive rivalry within an industry. In amount x. x below, the five makes argument by Porter is schematically illustrated:

Figure 2: An illustration of Porter's five pushes framework. The makes that determine the level of rivalry within an industry (i. e. industry elegance) are: 1. The threat of new entrants, i. e. how easy could it be for new organisations to get into the industry; 2. The bargaining ability of suppliers and clients, i. e. how much negotiation capacity to organisations and customers have, for example are they price takers or price manufacturers; 3. Threat of substitutes, i. e. are there many replacement products, and exactly how probably could it be that substitutes products will evolve in the near future.

The five causes of Porter connect with any market, home or global. The makes influence prices, costs and required opportunities as well as the return on investment (RoI) of a company. The bargaining ability of buyers affects the price a good may charge for a good or service. The bargaining electricity of suppliers affects the expenses of recycleables and other inputs and hence determines production costs. The threat of new entrants will depend on the investment necessary to access the marketplace, e. g. the plane industry has extremely high accessibility barriers because of its capital intensity, whereas starting a restaurant has relatively low obstacles to entry. The risk of substitutes depends on how easily products within an industry can be substituted and the likelihood of the industry products becoming outdated due to know-how. These pushes determine the intensity of rivalry in a industry and therefore, the industry appeal. In an industry where these causes are strong, and rivalry is high, it is much more difficult for organisations to use than if they are weak. The effectiveness of these forces may differ between sectors and as time passes.

Porter argues further, that for any firm to reach your goals in virtually any industry, it has to follow one of the three generic strategies he proposes. The common strategies are:

Cost Leadership

As the price leader, a company strives to really have the lowest cost located in its development process. In doing so, it can offer the cheapest prices within an industry. This is achieved by exploiting economies of level. Types of organisations that utilize this plan to day are Aldi and Ryanair.


A company can also try to distinguish their product in terms of quality and bill a premium for the extra value-added. An example of a firm that adopts this plan today is Apple.


A focus strategy is aimed at a niche market or special section of consumers. A good example of an company that uses a differentiation-focus strategy is Lamborghini.

Porter argues that it's necessary to follow one of the strategies in order to be successful. Firms that do not implement this and engage in more than one strategy are known as "stuck in the centre".

Figure 3: a schematic illustration of Porter's three general strategies

Hence, both key factors to achieve a lasting competitive advantage in line with the market established view will be the attractiveness of a business (power of rivalry) as well how an company positions itself within the industry composition. This competitive positioning explains why some firms are more profitable than others. Through their selection of strategy companies can improve or erode this position. Therefore, to accomplish a continual competitive advantage the market must be analysed to understand the perfect market fit. Porter summarizes this discussion by saying:

"[] competition reaches the core of the success or failing of businesses" Porter (2004)

A criticism of this approach is that it's a one-sided view, which only includes the framework of the industry but excludes the operations within a company. Furthermore, the access of resources may differ within one industry rather than all resources are homogenous.

The Resource Based mostly View of the Firm

No product is practical without producing positive monetary value, in doing so implying that extra value must be created out of its inputs. While additional value is necessary, it is not sufficient to accomplish a positive income. Profit requires the value to go over that of its opponents because under the assumptions of perfect competition, prices will be powered down, up until only normal earnings are being made. The Resource Based View (RBV) explicitly searches for the sources to achieve a SCA in the inner environment of an organization and in so doing, the factors that cause profits to vary. It then aims to explain why businesses in the same industry might change in performance.

The RBV examines the link between a firm's resources and a Sustained Competitive Advantage (SCA). As we realize it today, the RBV originates from Porter's value string logic, that was further produced by Barney (1991). Heading back even further, Alderson (1965) accepted that businesses should identify themselves before the buyer. Yet a far more direct predecessor can be found in Wernerfelt (1984).

The value string analysis is a process, whereby organizations can isolate and determine resources and features in their value string that differentiate them using their company competitors.

Barney (1991) reviewed the attributes that these isolated resources and features need to possess in order to explain a SCA.

It is important to point out that the RBV concentrates on how a SCA may be accomplished by the method of the internal resources rather than the exterior environment. Hence it is designed to explain dissimilarities in the performance of organisations within the same industry, based on differing internal tool endowments.

In order to comprehend the RBV, one must first specify what is recommended by resources.

"Company resources include all property, capabilities, organizational processes, firm qualities, information, knowledge, etc. manipulated by a firm that allow the firm to conceive of and put into practice strategies that improve its efficiency and success. "

(Barney, 1991a: 101)

Hence resources can be both, tangible or intangible. Which means they could be of physical (a factory), human (a worker), or organizational characteristics as well as also be included in what is known as a firm's functions. In contrast to the market centered view, the RBV assumes a firm's resources to be heterogeneous and imperfectly mobile and scarce.

The following cases will demonstrate the assumptions: Scarcity, imperfect flexibility and heterogeneity are necessary to ensure sustainability. For example, a reference that is merely scarce, like a superstar athlete for a sports team, could simply be hired by another team. His wage will keep increasing until a competitive benefits is no more generated. Imperfect flexibility means that resources cannot sell themselves to the best bidder and therefore the case previously mentioned is avoided. In practice this is created by businesses through non-competition clauses in contracts. Another example for learning resource immobility are co-specialized resources which are simply not worth as much when used outside very specific reference mixtures, e. g. Delta landing slot machines at Atlanta International airport and its long ranking customer loyalty in the region.

The central proposition of the RBV as stated by Barney (Barney, 1991a, 2002) is:

"for a firm to a achieve a state of continual competitive edge, it must acquire and control valuable, unusual, inimitable and non-substitutable (VRIN) resources and functions, plus have the organization (O) in place that can absorb and apply them. "

(Barney, 1991a, 2002)

In conditions of sustaining a competitive edge, isolating mechanisms become important. Isolating Mechanisms make reference to the economic forces that limit the scope to which a CA can be duplicated or neutralized through the reference creation activities of other firms. A good example here comes from the computer printer industry where Xerox's large service network (a learning resource), which produced a competitive advantages for some time was neutralized through Canon producing printers which simply seldom break, thereby getting rid of the necessity of service.

The value of managers within the RBV is the determined by their capacity to estimate the near future value of a resource more correct than competition, thereby providing the organization with an ex ante source of SCA. In the same way, isolating mechanisms provide an ex post way to obtain SCA. Isolating mechanisms describe why resources cannot be imitated sufficiently by other firms to contend with the firm that possesses the valuable resource. This includes factors such as causal ambiguity (when the foundation of the CA is undiscovered). This is more likely that occurs when the source of information in question is knowledge founded or socially intricate. Conner and Prahalad (1996) even refer to knowledge established resources as the "the substance of the resource-based point of view".

The RBV addresses one crucial shortfall of the MBV by detatching the assumption that the strategies companies go after and resources they control are equivalent. The MBV on the contrary assumes which should resource heterogeneity exist, it will be short lived as resources are mobile (can be purchased and sold in factor market segments). While those assumptions were useful in inspecting the exterior environment, it will now be evident that with the assumptions of resource immobility and heterogeneity, the RBV addresses a totally different and probably more realistic way.

Let us now consider the attributes prescribed as essential for resources by the RBV in turn:

Valuable - This refers to resources enabling a firm to "conceive of or use strategies that improve its efficiency and performance" (Barney 1991). This means that opportunities can be exploited and/or hazards in a firm's environment neutralized

Rare - Resources must be uncommon among a firm's current and potential competition. Which means that as soon as everybody possesses them, a competitive advantage can't be attracted from it.

Inimitable - While resources could possibly be the way to obtain a competitive gain, it requires inimitability to be able to create a sustained competitive benefit. Which means that other companies cannot obtain them. Reasons here include that to obtain the source unique historical conditions would be necessary, causal ambiguity i. e. other organizations are not able to understand the link between your resources and the firm's sustained competitive gain or social intricacy (interpersonal relations between employees for instance).

Non Substitutable - this feature refers to no strategically similar resource can be available that is not uncommon or imitable. If that would not be the situation, other organizations would simply use an alternative and erase the competitive advantages.

Organization - Here organization simply refers to an organization being in spot to use those resources.

Kraaijenbrink et al (2010) do an intensive review and evaluation of the critiques since Barney (1991) of the RBV. Their excellent work categories them into eight categories, each of which will be quickly summarized to give a history about the drawbacks:

(a) the RBV has no managerial implications - Here it is argued that the RBV suggest to acquire and develop VRIN resources yet it does not propose any way to do so, so that it is irrelevant for a manager's account. However, as the RBV aims to make clear existent SCA rather than aspiring to provide managerial description, this criticism while true misses the idea.

(b) the RBV signifies infinite regress - This refers to there never being an "ultimate" competitive benefit, yet it appears rather irrelevant and goes towards philosophical goals of management technology.

(c) the RBV's applicability is too limited - this refers to the question of what goes on to small organizations that do not possess resources of SCA or for occasion are pleased with their competitive situation.

(d) SCA is not achievable - As skills and resources and the way they are simply applied by organizations must constantly change, an equilibrium of constantly changing short-term advantages is established. While this is likely to be true in the long run, in the short run this can be false. The length of this substantial short run might be large when viewed from an buyers point of view. Yet here it ought to be highlighted again that the RBV provides ex girlfriend or boyfriend post explanations somewhat than ex girlfriend or boyfriend ante subscriptions which for illustration arise through information asymmetry.

(e) the RBV is not really a theory of the firm - true, but it never strived to be yet this will not compromise its capacity to describe competitive advantages.

(f) VRIN/O is neither necessary nor sufficient for SCA - Armstrong & Shimizu, 2007; and Newbert, 2007 for example are two recent reviews which underline the humble empirical support for the RBV and therefore imply significant other factors coming to work. Similarly, the RBV neglects areas of management that might be crucial for a company the truth is, but instead evaluation managers based on their potential to value future resources.

(g) the worthiness of a tool is too indeterminate to give useful theory - An extremely common criticism is usually that the RBV stand on tautoligicial statements which are true by explanation and hence cannot be tested. A good example here is Barney 1991 " Strong resources include all property, capabilities, organizational functions, firm attributes, information, knowledge, etc. handled by a firm that enable the organization to get pregnant of and implement strategies that improve its efficiency and success. "

(h) this is of reference is unworkable - While Barney (2001) argues that the effectiveness of the RBV is placed within its all-inclusiveness, at the same time this drives the theory towards explaining nothing at all as it offers everything. Hence it must be true, but is no longer strategically useful. In the same way you can simply include a SCA as a source then, thereby rendering the theory ineffective.

Discussion and Conclusion

When examining the two perspectives, both, the market- and the tool established view are fundamentally valid models to be able to achieve a lasting competitive advantage. With regards to managerial implications, both external (industry structure) as well as the inner environment (resources and features) of an organization are important in order to be successful. However, various criticisms have been increased towards both perspectives. Perhaps the greatest flaw of the two perspectives lies of their assumptions. The marketplace based mostly view assumes that resources are homogenous and flawlessly mobile. On the other hand, the resource founded view assumes that resources are not homogenous rather than properly mobile.

Recent trends in general management science reveal that knowledge and knowledge management of organizations are becoming increasingly important to be able to achieve and support a competitive gain. One argument here's that organizations may benefit enormously from sustaining the data with their retiring or giving workforce. This is specifically the truth because today, unlike customarily, people switch careers a lot more often. Employee to employer commitment has immensely decreased. Kransdorff and Williams metaphorically refer to this phenomenon in an article shared in the Harvard Business Review on Knowledge Management 2008, as 'golf swing doors and musical chairs'. Thus, if a business manages to capture and wthhold the knowledge or 'know-how' their workers developed before they leave, this is often a intangible source of a competitive benefit. Furthermore, structural changes available on the market, presented through the technological innovation of the internet, fundamentally change organizational conditions (Armstong, Hagel 1997). Today, a much better romance with customers can be developed to the magnitude that they are co-creating products. If properly executed the relationship developed in this process can even be a source of a sustainable competitive advantage. The relationship that can create a lasting competitive gain is referred to by Sawhney et al. (2005) as 'supporter experience'.

In finish, both universities of thought are essential to consider for any organization and also have their right of life. Nevertheless, fundamental changes which have evolved since that time such as structural changes in the marketplace also have to be recognized.
