VRIO

A four-question filter that turns a list of claimed strengths into a much shorter list of real advantages. Most things fail at the second question.

The printable canvas and the handoff into Claude Code are part of a paid plan. See what a plan includes. It needs the Claude desktop app on this machine, and your team and the prompt library already installed in that project — we cannot see your disk, so open it there.

What it is

Jay Barney's test for whether a resource produces sustained competitive advantage, applied as four questions in sequence. A resource has to pass all four; failing any one places it in a weaker category, and the framework is honest about how few things survive.

Valuable
Does it let you exploit an opportunity or defend against a threat? If no, it is a competitive disadvantage — you are carrying cost for nothing.
Rare
Do only a few competitors possess it? Valuable but common gets you competitive parity: necessary to compete, not a reason anyone picks you.
Costly to imitate
Can rivals acquire or copy it without significant cost or time? Valuable and rare but imitable gives you a temporary advantage — real, but on a clock.
Organised to capture value
Are your structure, systems and incentives arranged to exploit it? Passing the first three but failing this means you hold an advantage you cannot use.
The verdict
Only all four together give sustained competitive advantage. Anything less should be labelled accurately, because a temporary advantage managed as a permanent one is how firms get overtaken.
The mistake people makePeople run VRIO on things they are proud of rather than things that are rare. The useful discipline is to ask the Rare question second and brutally — it removes most of the list, and what survives is worth the rest of the analysis.
What it’s forYou want to test whether a claimed strength is a durable advantage or just something you happen to be good at.
What it’s not forYou have not listed your capabilities yet. VRIO is a filter, not a generator.

How you run it

  1. List the resources, not the aspirationsTangible and intangible: assets, relationships, data, brand, skills, processes. Things you have, not things you intend to build.
  2. Ask whether it is ValuableDoes it let you exploit an opportunity or neutralise a threat? If it does neither it is a cost, not a resource.
  3. Ask whether it is RareDo few competitors have it? Most claimed strengths die here — everyone has good people and a strong culture.
  4. Ask whether it is costly to ImitateCould a competitor get it, and what would it take? Time, money, history, luck. Something copyable in a year is not an advantage, it is a lead.
  5. Ask whether the Organisation can exploit itDo the structure, processes and incentives let you actually use it? Plenty of firms hold advantages they cannot bring to bear.

The prompt

Two ways to run it

Run this tool in your own Claude

The short prompt starts your partner against the library on your disk. The long one carries everything with it and needs nothing installed.

🔒 Prompt locked

Everything above is free — what this tool is, what it is for, what it is not for, and how to run it as a workshop. Three tool prompts a month are free with an account; beyond three, and for the printable canvas, it is the paid part.
