The core idea
Barney’s 1991 resource-based argument links sustained competitive advantage to heterogeneous resources that competitors cannot easily reproduce or replace. Its familiar criteria are value, rarity, imperfect imitability and non-substitutability: VRIN. Later VRIO formulations add organisation as an explicit question, but should not be presented as the identical 1991 framework. HR applications often focus on collective knowledge, coordination and relationships rather than an isolated “star” employee.
Source and attribution [1]Using it in practice
Describe a capability as something the organisation can reliably do. Identify the people, tools, routines and relationships supporting it. Ask what a competitor could buy tomorrow and what would require years of shared learning. Then assess fragility: a supposedly distinctive capability held by one exhausted specialist may be a continuity risk. Development, knowledge sharing and fair retention practices can be more useful than simply paying for scarce credentials.
An example, not a reported case
Worked example · illustrative
A small engineering firm resolves unusual installation problems quickly. Its advantage is not just certification: technicians trust one another, share failure histories and know which design specialist to call. HR builds mentoring time and succession cover into the operating plan. It evaluates whether new technicians can solve unfamiliar cases with support, rather than counting course attendance as the capability itself.
What to watch for
Value is contextual and can disappear as customer needs change. A valuable workforce should not be treated merely as property: employees have agency, rights and options.

Three useful questions.
- What can we do reliably that matters to customers?
- How is that capability reproduced?
- Where is the single point of failure?
