The MOAT framework: scoring an idea on Margin, Operations, Advantage and TAM

Why four scores beat one gut feeling

Ideas rarely fail for a general reason. They fail for a specific one: there was no margin, it could not run without the founder, anyone could copy it, or there were not enough buyers. One overall impression hides which of those is the problem. Scoring each part on its own forces you to look at the one you have been quietly avoiding.

How to score each part

• Margin: what is left from one sale after the real cost of delivering it, including your time. A 2 barely breaks even after materials, fees and hours. An 8 keeps most of each sale, like a service priced on value or software sold many times over.
• Operations: whether it can be run and delivered as it grows. A 2 only works if you personally do every job. An 8 has steps written down that someone else could follow on Monday.
• Advantage: what stops a competitor copying you and winning on price. A 2 could be copied next week. An 8 has something others cannot easily get: contracts, a location, a licence, a reputation or data.
• TAM: how many real buyers you can reach. A 2 is a few hundred possible customers. An 8 is many buyers you can actually get in front of, with room to grow.

A worked example

Take a hypothetical mobile dog-grooming van. Margin scores a 7: it is a service with cheap supplies, and customers pay for convenience. Operations scores a 5: one van works, but growing means hiring groomers you can trust. Advantage scores a 4: another van can start next month, and only repeat customers and local reviews hold them off. TAM scores a 6: there are plenty of dog owners within a short drive, but only so many a van can reach in a day.

7 + 5 + 4 + 6 = 22 out of 40. Not a no, but not ready. Fix the weakest score first.

The score tells you where to work. A membership that books every customer every six weeks lifts Advantage, because loyal regulars are harder to poach. A written grooming checklist lifts Operations, because a new hire can follow it. Score it again after the changes and see whether it crosses 30.

Reading the score

The lowest score usually decides the outcome. Fix that one, or don't start.

A 9 for Advantage means little if Margin is a 2, and a huge market is worthless if the operation cannot serve more than ten customers. Read the total for a verdict and the lowest score for your next job.

Score it without grading your own homework

The framework works with a notebook. The catch is that it is your idea, so you will score your own margin generously. The MOAT Evaluator on BizWax.Ai scores the idea on all four parts using a panel of AI models instead of one, shows where they agree and where they split, and gives a plain FUND IT, FIX IT or FLEE IT verdict. You get an outside read in a minute, before you spend money finding out the hard way.
