Two of These Are Fatal. The Other Three Are a Fortnight's Work.
A weak value proposition is the most severe cause of failure, not the most common. The useful skill is telling a recoverable problem from a fatal one.

You were told that course businesses fail because of weak value propositions, and you were told it by people who mostly know what they are talking about, including me.
Here is what it looks like from closer up. Across the businesses I have watched fail or been asked to look at afterwards, the value proposition was the cause in a minority of cases. What it was, in almost every case, was the worst cause — the one where no amount of subsequent effort helps.
That is worth separating out, because severity and frequency are different things and confusing them produces a specific expensive mistake: people abandon businesses whose problem was a fortnight's work, and persist for years with businesses whose problem was terminal in month one.
So the question is not what is wrong. It is which kind of wrong.
The three recoverable ones
Start here, because this is where most struggling businesses actually are.
Nobody knows you exist yet. No traffic, no list, no reach. The offer has never been in front of enough of the right people for the market to have an opinion about it.
This feels like failure and is not a result at all. There is no information in it. You cannot learn anything about demand from an audience of nobody, and the fix is not a better idea — it is distribution, repeated, for longer than feels reasonable.
The offer is not legible. People arrive and cannot tell what you do.
I have gone to course business websites and genuinely not been able to work out what they were. Not whether I wanted it — what it was. And when that happens I click off, and so does everyone else, because you have handed the visitor a job and they did not come to do a job.
That failure is invisible to the founder, permanently, because you already know what you meant. It is also fixable in an afternoon by anyone willing to ask five people in their profession to read the top of the page and say what the business does.
The price is wrong, or the product does not do what the page promised. Both show up in the same place — people buy and then something goes wrong afterwards, in refunds, in silence, in a second product that nobody takes.
Also fixable. Prices can be changed. Products can be improved and reissued. Neither requires you to start again.
There is one specific version of "not working" I am deliberately leaving alone here: a subscriber list that keeps growing while sales stay at zero. That has its own diagnosis and it is usually about reading the result too early rather than about anything being broken.
The two fatal ones
Now the other category, and the reason the headline exists.
Nobody has the problem badly enough. You picked something real, that people recognize, and would like solved — and would not pay to solve, because it costs them nothing much to keep having it.
This is the actual value-proposition failure and it is fatal in the strict sense: better marketing makes it worse, because more people arrive and decline. A lower price does not help either, since the objection was never price. The only repair is to change what you are solving, which means the business you have has to end for a different one to start.
You cannot reach the people who do have it. Rarer, and just as final. The problem is real and painful, and the people with it are not in any group, not searching for anything, not reachable through any channel you can afford. A market you cannot address is not a market.
How to tell which one you are in
Four questions, in order. Stop at the first one that answers itself.
Has enough of the right kind of person actually seen it? If not, you do not have a diagnosis yet, you have a distribution problem, and everything below is premature.
Can a stranger in your profession say what you do, out loud, after reading the top of your page? Go and check rather than assuming. If they cannot, fix that before you touch anything else.
When people decline, what do they say? "Too expensive" is a price or a value-communication problem and is recoverable. "I'll come back to it" and a general vagueness is usually the fatal one — the problem is not urgent enough to act on.
Do the people who buy get the result? If they do not, that is a product problem, and the most urgent of the three, because it is the one that damages you permanently by reputation.
The mechanism that keeps a proposition strong as you grow
One structural thing, because legibility decays as a business gets bigger and this is how you stop it.
Your business has one proposition. Each product has its own. Those are different objects and they sit in a hierarchy: the business-level statement says who you help and with what, and every course underneath it has a narrower statement that feeds the same mission.
Get that hierarchy right and you can add ten products without the business becoming harder to describe. Get it wrong — treat each new course as an extension of the top-level promise rather than a member of it — and the sentence at the top of your site acquires another clause every year until it says nothing.
That sentence should be short enough to sit under the name of your business and specific enough that a colleague could repeat it accurately. It is the compass for your content, your products and your ads, and when it goes vague everything downstream of it goes vague at the same time.
So: before you rewrite your value proposition, find out whether it is the thing that is broken. It is the most serious problem you can have. It is rarely the one you actually have.
