What the test is actually measuring
Not whether the idea is good. Not whether people like it. One thing only: will a stranger commit something before receiving anything?
That is the only question that predicts whether the business exists. Everything else — the name, the logo, the vehicle branding, the price list design — is decoration on an assumption. If the assumption is wrong, the decoration is money you burned proving it.
Day 0: write one sentence
Before anything moves, get the offer into a single sentence containing four things:
- Who it is for — specific enough that someone recognises themselves. "Homeowners in [suburb]" not "people".
- The specific job — the thing that gets done, not the category. "Clean and seal a double driveway" not "cleaning services".
- The price — a real number or a tight range. This is the part people want to leave out, and it is the part that makes the test work.
- The turnaround — "this Saturday", "within three days", "same week".
"For homeowners in Brackenfell — I'll pressure-wash and re-sand a standard double driveway for R350, this Saturday or next, about two hours, I bring my own water."
Everything a buyer needs to decide, in one line. No business name. No logo. No website.
If you cannot fit it into one sentence, the offer is not clear enough to test yet. That is a finding, not a delay — vagueness at this stage becomes an unsellable service later.
Day 1: put it in front of 20 real people
Twenty is the working minimum. Fewer and a zero result tells you nothing — it might just be a quiet week.
- Three to five local community groups. Read the rules first; most SA groups restrict trading posts to certain days or sections, and getting removed costs you the channel for good.
- Ten direct messages to people who genuinely fit the description. Not your mother. Not your best friend. People who would plausibly buy this from a stranger.
- One or two physical spots — the hardware notice board, the sports club, the laundromat.
Do not build anything. No domain, no Canva logo, no business cards. If the test says yes you will have plenty of time to build; if it says no you will be glad you did not.
Day 2: ask for a commitment, not an opinion
This is where almost every informal validation attempt quietly fails. People ask "would you use something like this?" and get a warm yes, because saying yes to a hypothetical is free and saying no to a friend is awkward.
Ask for something that costs the other person something:
| Counts as a yes | Counts as zero |
|---|---|
| A booked date and an address | "That's a great idea" |
| A deposit, even R50 | "Definitely let me know when you start" |
| "Come Saturday at 9" | "I'd probably use that" |
| A name and number on a waiting list, given unprompted | A like or a thumbs-up |
Count honestly. The temptation to score encouragement as validation is enormous, and giving in to it is how people end up with a garage full of equipment and no clients.
Day 3: count and decide
At 72 hours, stop and read the number:
- Two or more commitments. Proceed. Do the work, get paid, and only then buy the next thing you need. The first three clients pay for the gear.
- One commitment. Something works but something else does not. Change one variable — usually price first, then the buyer description — and rerun in a different set of groups. One change at a time, or you learn nothing.
- Zero commitments. The offer, the price or the audience is wrong. Rewrite the sentence and run it once more. If it comes back zero again, drop the idea and move to the next one. You have spent three days and no money, which is the entire point.
A zero at 72 hours is not a failure — it is the test doing exactly what you built it for. The failure is the version where you skipped the test, bought R8 000 of gear, and reached the same zero four months later with the money already gone.
The three ways people cheat the test
- Testing on people who love you. Friends and family buy you, not the offer. Their yes does not transfer to strangers.
- Removing the price to get more interest. It works — interest goes up and information goes to zero. The price is not an obstacle to the test, it is the test.
- Extending the deadline. "I'll give it another week" is almost always a way to avoid reading a zero. The deadline is there to protect you from your own spending, not to hurry the buyer.
After a yes
Deliver the first job before improving anything. You will learn more in two hours of actually doing the work — what it really costs you, how long it really takes, what the client actually complains about — than in two weeks of planning. Then price the second job properly using what you learned, and keep the overhead near zero until income is steady.
