Corcoran describes her early innovation advantage under one word: urgency. When she thought of an idea on Monday, she aimed to have it in the market by Tuesday. Before acting, she asked whether anyone else was already doing it; if not, she treated the difference as a reason to test rather than a reason to wait. The model assumes a portfolio of experiments, not certainty about each attempt: roughly one of five ideas may work, so the process must remain fast and survivable. This let a small company move before larger firms could clear committees, lawyers, and approvals. The mechanism is a short cycle from idea to differentiation check to live trial to observed response, followed by another attempt rather than prolonged defense of a failed idea.
Origin
Corcoran used urgency and rapid experimentation to compete with large, complacent New York real-estate firms.
Core principles
- 01Urgency is an advantage against slower incumbents
- 02A differentiated idea is worth a quick test
- 03Most tests can fail if the occasional winner pays
How to run it
- 1
Frame the idea
State the new tactic clearly enough that it can be tested rather than discussed in the abstract.
Pro tip Reduce it to one observable change in the market.
- 2
Check for difference
Ask whether competitors already use the same tactic. If they do not, identify the advantage customers might notice.
Pro tip Use competitor inaction as a test signal, not proof of wisdom.
Watch out Novelty alone does not make an idea useful.
- 3
Ship the minimum test
Put the smallest real version in front of the market by the next day when practical.
Pro tip Keep the test cheap enough that several failures are affordable.
Watch out Do not use speed to bypass legal or safety requirements.
- 4
Read and repeat
Observe whether the test creates the intended response, keep the winner, and move quickly to the next idea when it does not.
Pro tip Judge the portfolio of tests rather than expecting every idea to win.
In the wild
Against large firms slowed by committees and approvals, Corcoran repeatedly launched different tactics as soon as she thought of them and expected only a minority to work.
→ Her speed created a competitive advantage even though individual experiments sometimes failed.
Common mistakes
Waiting for certainty
Prolonged deliberation gives slower incumbents time to catch up and prevents the market from supplying evidence.
Betting everything on one test
Corcoran's logic expects several attempts for each success, so each experiment must be survivable.
Is it for you?
Best for
Small teams that can run cheap, reversible market experiments quickly.
Not ideal for
Regulated, dangerous, expensive, or irreversible changes that require careful validation before launch.

“I think it all comes Under the Umbrella of urgency if I thought of an idea on a Monday I had on the street by…”
“if I thought of an idea I asked myself is anyone else doing it and no one else was doing I said let's give it…”
“you try five things one thing works okay but I kept trying different things different things”
