Critically assess the usefulness of the resource-based view for explaining sustained competitive advantage in UK retail.
Since Barney’s (1991) formalisation of the resource-based view, the proposition that sustained competitive advantage derives from firm-specific resources that are valuable, rare, inimitable and non-substitutable, rather than from favourable industry positioning, has become one of the most cited frameworks in strategic management. UK retail is an unusually demanding test of this proposition: it is a sector characterised by thin margins, intense price competition, low switching costs for consumers, and repeated waves of disruption from discount entrants, online-only rivals and changing shopping behaviour since the 2008 financial crisis. If sustained advantage in such a volatile, low-differentiation sector can be explained through internal resources rather than market structure, the resource-based view’s claim to generality is considerably strengthened; if it cannot, the theory’s limits become correspondingly clearer.
This essay critically assesses the usefulness of the resource-based view for explaining sustained competitive advantage in UK retail. It argues that while the framework offers real explanatory power for firms such as Aldi and Ocado, whose advantage rests on genuinely rare and difficult-to-imitate operational capabilities, its static conception of resources and its neglect of the competitive dynamics that erode advantage over time leave it substantially incomplete as an explanation of retail performance, and that dynamic-capabilities and institutional perspectives are required to supplement it.
The analysis proceeds through illustrative case evidence drawn from UK retail rather than a single-firm study, on the grounds that the resource-based view makes a general claim about the sources of sustained advantage that should be testable across firms of differing size, format and ownership structure. Aldi, Lidl and Ocado are used as cases where the framework’s predictions appear to hold reasonably well; Debenhams, Arcadia and Marks & Spencer are used as cases that expose its limitations; and the John Lewis Partnership and Tesco are used to probe the boundary conditions under which VRIN resources do and do not translate into sustained financial performance. This comparative approach follows the view, consistent with Peteraf’s (1993) cornerstones framework, that the resource-based view is best evaluated not through single case narratives, which risk selecting only confirming evidence, but through a range of cases spanning both apparent successes and apparent anomalies.
Barney’s (1991) contribution was to shift strategic analysis inward, arguing that where resources are heterogeneously distributed across firms and imperfectly mobile between them, those that are valuable, rare, imperfectly imitable and non-substitutable can be a source of sustained competitive advantage regardless of industry structure. This built on Wernerfelt’s (1984) earlier reframing of the firm as a bundle of resources rather than a portfolio of product-market positions, and stood in explicit contrast to Porter’s (1980) positioning school, which located advantage primarily in the structural attractiveness of an industry and a firm’s position within it. Peteraf (1993) later formalised the cornerstones underpinning sustained advantage as heterogeneity, ex post limits to competition, imperfect resource mobility and ex ante limits to competition, providing a more rigorous microeconomic foundation for Barney’s original insight.
Applied to retail, the framework directs attention to resources such as supplier relationships, logistics infrastructure, brand equity, proprietary data and organisational culture, rather than to shelf-space or store-count alone. Aldi and Lidl’s advantage in the UK grocery market is instructive: their gross margins persistently exceed those of larger incumbents despite lower prices, an outcome attributable less to store location than to a tightly integrated operating model built around a restricted stock-keeping-unit range, standardised store formats and long-term supplier partnerships that are difficult for a full-range incumbent to replicate without cannibalising its existing offer. This is precisely the kind of causally ambiguous, organisationally embedded advantage the VRIN framework was designed to capture, since a rival cannot simply purchase the same resource on an open market.
A further application concerns Ocado, whose advantage rests substantially on proprietary automated-warehouse and robotics technology developed over more than a decade, protected by patents and tacit engineering know-how that has proven difficult even for well-resourced rivals to replicate quickly, evidenced by Ocado’s subsequent licensing of its Smart Platform to international grocers including Kroger. Here the inimitability criterion is satisfied not merely by legal protection but by the accumulated, path-dependent nature of the capability itself, consistent with Dierickx and Cool’s (1989) argument that some resources cannot be bought but must be built over time through a process of asset-stock accumulation.
Sainsbury’s and Waitrose provide a further, more equivocal illustration of the VRIN logic applied to brand equity as a resource. Waitrose’s reputation for quality and provenance is genuinely difficult for a discount or mid-market rival to replicate quickly, since it depends on decades of accumulated supplier relationships and a premium positioning that is costly to reverse-engineer, satisfying Barney’s (1991) rarity and imitability criteria in a manner consistent with the framework’s predictions. Yet Waitrose’s market share has continued to erode against both discount entrants and premium online specialists over the past decade, illustrating Barney’s own, sometimes overlooked, distinction between a resource that generates temporary above-normal returns and one capable of sustaining advantage indefinitely; possessing a valuable and rare resource is not, on Barney’s own terms, a guarantee of permanence, only of an advantage that persists for as long as the resource remains uncopied and undiminished in relative value.
Despite these illustrative successes, the resource-based view’s central weakness in a sector as fast-moving as UK retail is its comparatively static conception of what counts as a valuable resource. Priem and Butler (2001) raise the influential critique that VRIN risks tautology: a resource is deemed a source of advantage because a firm outperforms rivals, and the firm is said to outperform rivals because it possesses the resource, with no independent, ex ante means of identifying which resources will prove valuable before the fact. In UK retail this problem is not merely academic. Debenhams and Arcadia Group possessed brand equity, extensive retail floorspace and long supplier relationships that would, on a static VRIN reading, have appeared to satisfy several of Barney’s criteria, yet both entered administration between 2019 and 2021 as the same resources that had once conferred advantage became liabilities once consumer behaviour shifted decisively toward online channels.
This points to a second and related weakness: the resource-based view offers limited guidance on how resources should evolve as the competitive environment changes, because its unit of analysis is the resource itself rather than the process by which resources are reconfigured. Teece, Pisano and Shuen’s (1997) dynamic-capabilities extension was developed precisely to address this gap, arguing that in rapidly changing environments it is not the possession of valuable resources but the capacity to sense opportunities, seize them through resource reconfiguration, and transform the organisation accordingly that sustains advantage. Marks & Spencer’s protracted difficulty translating strong brand equity and supplier relationships into online and fast-fashion competitiveness during the 2010s, followed by its subsequent partial recovery through supply-chain and digital investment under new leadership, illustrates a firm whose static resource base was insufficient without the dynamic capability to redeploy it.
A third limitation concerns the framework’s relative silence on demand-side and institutional factors. Kraaijenbrink, Spender and Groen (2010) argue that RBV underspecifies the role of the product market in determining whether a resource that is valuable to the firm is also valued by consumers, a distinction that matters greatly in fashion retail, where brand resources such as Ted Baker’s or Boohoo’s design heritage lost commercial value not because the resource itself changed but because consumer taste and, in Boohoo’s case, scrutiny of supply-chain labour practices shifted the market’s valuation of that resource. A resource-based analysis focused solely on internal VRIN characteristics offers little purchase on this kind of externally driven devaluation.
These conceptual weaknesses are compounded by a weak empirical base. Newbert’s (2007) systematic review of resource-based-view studies found that only a minority of empirical tests fully supported the VRIN model’s predictions once methodological quality was controlled for, with resource value and rarity receiving more consistent support than inimitability or non-substitutability, the two criteria most central to explaining sustained, as opposed to merely temporary, advantage. Applied to UK retail, this asymmetry is telling: value and rarity are relatively straightforward to identify in hindsight, as with Ocado’s platform or Aldi’s operating model, but inimitability is precisely the criterion that events such as the rapid, sector-wide adoption of loyalty-card data analytics following Tesco’s Clubcard success called into question, since a resource that can be substantially imitated within a decade offers a weaker claim to sustained advantage than the theory’s own terminology implies.
A more defensible position integrates the resource-based view with the dynamic-capabilities and institutional perspectives that address its principal weaknesses, rather than treating RBV as a complete theory in its own right. Eisenhardt and Martin (2000) argue that dynamic capabilities themselves display commonalities across firms and industries that undermine any claim to inherent rarity, which suggests that in retail the source of sustained advantage may lie less in the capabilities themselves than in the speed and fit with which they are deployed relative to the specific evolution of a firm’s market. This reframing helps explain why Tesco’s data-driven Clubcard capability, though widely studied and partially emulated by Sainsbury’s Nectar and other loyalty schemes, has nonetheless continued to generate advantage: the capability is not unique in kind, but its scale, historical depth of data, and integration with Tesco’s broader supply-chain and pricing systems make full replication commercially unattractive even where technically feasible (Humby, Hunt and Phillips, 2008).
The John Lewis Partnership offers a further test case for this reconciled view. Its employee-ownership structure is a resource that is genuinely rare among large UK retailers and difficult to imitate, since imitation would require a fundamental change of corporate form rather than a strategic choice within an existing form, satisfying Barney’s inimitability criterion in an unusually strong sense. Yet the Partnership’s declining profitability during the 2020s despite this rare resource demonstrates that VRIN characteristics are necessary rather than sufficient: a rare and inimitable resource still requires effective managerial choices about pricing, format and channel investment to translate into sustained financial advantage, a point consistent with Barney’s (1991) own, sometimes overlooked, qualification that resources are a source of only potential advantage absent appropriate strategy and organisation.
This synthesis also has practical implications for how UK retailers should approach strategic resource investment. Rather than treating VRIN as a static checklist applied once, the evidence from Aldi’s continuous refinement of its supply chain, Ocado’s ongoing platform development and Tesco’s evolving data capability suggests that sustained advantage in retail is better understood as an ongoing process of resource renewal under dynamic-capability logic, in which VRIN analysis identifies which renewed resource configurations are worth pursuing at a given point in time rather than providing a single, once-and-for-all explanation of advantage.
A complementary resource-based perspective worth noting is Grant’s (1996) knowledge-based view, which treats the firm’s capacity to integrate specialist knowledge held by individuals, such as buying teams’ supplier expertise or merchandising judgement, as itself a distinct and valuable resource. In UK retail this is significant because much of what distinguishes a successful buying or category-management function is genuinely tacit and slow to codify, meaning that even where a competitor hires away individual buyers, the integrative routines that combine their judgement with a firm’s existing supplier network and data infrastructure are harder to transplant wholesale, offering a partial explanation for why firms such as Next have sustained comparatively strong retail performance despite operating in a sector where individual talent is, in principle, mobile between employers.
This knowledge-based extension also helps reconcile an apparent tension within the resource-based literature between individual mobility and organisational stickiness. Grant (1996) argues that competitive advantage rests less on any single expert’s knowledge than on the organisation’s routines for coordinating dispersed, specialist knowledge toward a common commercial purpose, a coordination capability that does not leave the firm when an individual employee does. Applied to Next’s buying function, this suggests that the firm’s advantage is better attributed to its integrative merchandising and supply-chain routines, refined over successive trading cycles, than to any identifiable set of individually rare employees, a distinction with practical implications for how retailers should think about talent retention versus organisational-process investment when seeking to defend a resource-based advantage.
A further critical consideration, often underweighted in resource-based accounts, is that UK retail’s competitive dynamics are also shaped by industry-level and regulatory forces that operate largely independently of firm-specific resources, in a manner closer to Porter’s (1980) original positioning logic. Business rates reform, planning restrictions on out-of-town development, and the statutory Groceries Supply Code of Practice all alter the relative attractiveness of different retail formats and supply-chain strategies in ways that no individual firm’s resource base determines. The discount grocers’ rise, for instance, cannot be explained by their resources alone; it also required a permissive planning environment for smaller-format stores and a post-2008 shift in consumer price sensitivity that altered the entire industry’s demand structure, conditions external to any single firm’s VRIN endowment.
This suggests that a purely resource-based account risks overstating the extent to which sustained advantage is under managerial control, and understating the extent to which it depends on a favourable conjunction between a firm’s resources and an industry environment that is itself subject to regulatory and macroeconomic shifts largely beyond the firm’s influence. Amit and Schoemaker’s (1993) concept of strategic industry factors, which mediates between industry structure and firm-specific resources, offers a useful corrective, proposing that the value of a given resource is partly endogenous to the industry conditions prevailing at a given time, such that the same resource bundle may confer advantage in one regulatory or macroeconomic environment and prove far less valuable in another.
The 2022-23 UK cost-of-living and energy-price crisis provides a recent illustration of this endogeneity. Retailers whose resource base was oriented toward premium positioning, such as certain mid-market fashion and homeware chains, found the relative value of that resource compressed almost overnight as consumer spending shifted toward value retailers, while Aldi and Lidl’s already cost-efficient operating model became relatively more, rather than less, valuable under the same macroeconomic shock. No change occurred to either group of firms’ internal resource base during this period; what changed was the external valuation of those resources under a shifted demand environment, a dynamic that a purely internal, firm-level resource-based analysis is not well equipped to anticipate or explain.
Institutional theory offers a further corrective largely absent from resource-based accounts. DiMaggio and Powell’s (1983) concept of mimetic isomorphism, whereby organisations facing uncertainty imitate the visible practices of successful peers, helps explain why loyalty schemes, click-and-collect infrastructure and, more recently, environmental, social and governance reporting practices have converged rapidly across UK retailers regardless of firm-specific resource endowments. Such convergence directly erodes the rarity criterion on which sustained advantage depends: a resource or practice adopted defensively by an entire industry within a few years, as loyalty-card analytics broadly were after Tesco’s Clubcard demonstrated their value, cannot for long remain a source of differential advantage, however valuable it may be in absolute terms, since VRIN logic requires relative rather than merely absolute value to explain sustained rather than industry-wide gains.
This essay has argued that the resource-based view retains genuine explanatory value for UK retail, particularly in accounting for the durable advantages of firms such as Aldi and Ocado, whose operational and technological resources satisfy the VRIN criteria in a demonstrable and empirically observable way. However, the framework’s static conception of resources, its vulnerability to Priem and Butler’s tautology critique, and its comparative silence on demand-side, institutional and industry-structural forces mean that it cannot stand alone as an explanation of sustained advantage in a sector as volatile as UK retail. The collapse of Debenhams and Arcadia despite substantial legacy resources, and Marks & Spencer’s prolonged difficulty redeploying its brand and supplier assets, both demonstrate that resource possession without dynamic reconfiguration capability is insufficient, while John Lewis’s rare ownership structure alongside declining profitability shows that VRIN characteristics are necessary but not sufficient conditions for advantage.
For strategic-management practice, the implication is that UK retail executives should treat VRIN analysis as a diagnostic starting point rather than a terminal answer, supplementing it with an explicit assessment of how quickly a given resource is likely to be imitated or rendered less relevant by institutional convergence, regulatory change or shifting consumer valuation, and with a deliberate investment in the dynamic capabilities needed to reconfigure resources as those conditions shift. The most defensible theoretical position, consistent with Teece, Pisano and Shuen (1997), Amit and Schoemaker (1993) and DiMaggio and Powell (1983), treats the resource-based view as one component within a broader analytical framework that must also incorporate dynamic-capability, institutional and industry-structural analysis, rather than as a self-sufficient theory of sustained competitive advantage in UK retail.
