The resource-based view (RBV) is a managerial framework used to determine the strategic resources with the potential to deliver comparative advantage to a firm. These resources can be exploited by the firm in order to achieve sustainable competitive advantage.
Barney's 1991 article "Firm Resources and Sustained Competitive Advantage" is widely cited as a pivotal work in the emergence of the resource-based view. However, some scholars argue that there was evidence for a fragmentary resource-based theory from the 1930s. RBV proposes that firms are heterogeneous because they possess heterogeneous resources, meaning firms can have different strategies because they have different resource mixes.
The RBV focuses managerial attention on the firm's internal resources in an effort to identify those assets, capabilities and competencies with the potential to deliver superior competitive advantages.
During the 1990s, the resource-based view (also known as the resource-advantage theory) of the firm became the dominant paradigm in strategic planning. RBV can be seen as a reaction against the positioning school and its somewhat prescriptive approach which focused managerial attention on external considerations, notably industry structure. The so-called positioning school had dominated the discipline throughout the 1980s. In contrast, the emergent resource-based view argued that the source of sustainable advantage derives from doing things in a superior manner; by developing superior capabilities and resources. Jay Barney's article, "Firm Resources and Sustained Competitive Advantage" (1991), is seen as pivotal in the emergence of the resource-based view.
A number of scholars point out that a fragmentary resource-based perspective was evident from the 1930s, noting that Barney was heavily influenced by Wernerfelt's earlier work which introduced the idea of resource position barriers being roughly analogous to entry barriers in the positioning school. Other scholars suggest that the resource-based view represents a new paradigm, albeit with roots in "Ricardian and Penrosian economic theories according to which firms can earn sustainable supranormal returns if, and only if, they have superior resources and those resources are protected by some form of isolating mechanism precluding their diffusion throughout the industry." While its exact influence is debated, Edith Penrose's 1959 book The Theory of the Growth of the Firm is held by two scholars of strategy to state many concepts that would later influence the modern, resource-based theory of the firm.
The RBV is an interdisciplinary approach that represents a substantial shift in thinking. The resource-based view is interdisciplinary in that it was developed within the disciplines of economics, ethics, law, management, marketing, supply chain management and general business.
RBV focuses attention on an organisation's internal resources as a means of organising processes and obtaining a competitive advantage. Barney stated that for resources to hold potential as sources of sustainable competitive advantage, they should be valuable, rare, imperfectly imitable and not substitutable (now generally known as VRIN criteria). The resource-based view suggests that organisations must develop unique, firm-specific core competencies that will allow them to outperform competitors by doing things differently.
Although the literature presents many different ideas around the concept of the resource-advantage perspective, at its heart, the common theme is that the firm's resources are financial, legal, human, organisational, informational and relational; resources are heterogeneous and imperfectly mobile and that management's key task is to understand and organise resources for sustainable competitive advantage. Key theorists who have contributed to the development of a coherent body of literature include Jay B. Barney, George S. Day, Gary Hamel, Shelby D. Hunt, G. Hooley and C.K. Prahalad.
Achieving a sustainable competitive advantage lies at the heart of much of the literature in both strategic management and strategic marketing. The resource-based view offers strategists a means of evaluating potential factors that can be deployed to confer a competitive edge. A key insight arising from the resource-based view is that not all resources are of equal importance, nor possess the potential to become a source of sustainable competitive advantage. The sustainability of any competitive advantage depends on the extent to which resources can be imitated or substituted. Barney and others point out that understanding the causal relationship between the sources of advantage and successful strategies can be very difficult in practice. Thus, a great deal of managerial effort must be invested in identifying, understanding and classifying core competencies. In addition, management must invest in organisational learning to develop, nurture and maintain key resources and competencies.
In the resource-based view, strategists select the strategy or competitive position that best exploits the internal resources and capabilities relative to external opportunities. Given that strategic resources represent a complex network of inter-related assets and capabilities, organisations can adopt many possible competitive positions. Although scholars debate the precise categories of competitive positions that are used, there is general agreement, within the literature, that the resource-based view is much more flexible than Porter's prescriptive approach to strategy formulation.
The key managerial tasks are:
1) Identify the firm's potential key resources.
2) Evaluate whether these resources fulfill the following criteria (also known as VRIN criteria:
3) Develop, nurture and protect resources that pass these evaluations.
Given the centrality of resources in terms of conferring competitive advantage, the management and marketing literature carefully defines and classifies resources and capabilities.
Barney defines firm resources as: "all assets, capabilities, organizational processes, firm attributes, information, knowledge, etc. controlled by a firm that enable the firm to conceive of and implement strategies that improve its efficiency and effectiveness" 
Capabilities are "a special type of resource, specifically an organizationally embedded non-transferable firm-specific resource whose purpose is to improve the productivity of the other resources possessed by the firm." 
Firm-based resources may be tangible or intangible.
Firms in possession of a resource, or mix of resources that are rare among competitors, are said to have a comparative advantage. This comparative advantage enables firms to produce marketing offerings that are either (a) perceived as having superior value or (b) can be produced at lower costs. Therefore, a comparative advantage in resources can lead to a competitive advantage in market position.

Although scholars debate the precise categories of competitive positions that are used, there is general agreement, within the literature, that the resource-based view is much more flexible than Porter's prescriptive approach to strategy formulation. Hooley et al. suggest the following classification of competitive positions:
