Joseph Schumpeter, writing in 1942, was arguing against a picture of competition as firms in a stable industry undercutting each other on price.

That is not the competition that matters, he said. The competition that matters is the new commodity, the new technology, the new source of supply, the new type of organization — competition which strikes not at the margins of existing firms but at their foundations and their very lives.

He called the process creative destruction, and it is the essential fact about capitalism, not a disturbance to it.

The part usually skipped

The phrase gets used as a cheerful synonym for progress. Schumpeter meant something harder.

The destruction is real and it lands on specific people. Firms fail, skills become worthless, towns built around an industry lose the industry, and the aggregate gain does not reach the individuals who paid. Creation and destruction are the same event seen from two sides, and which side you are on is not a matter of merit.

He also thought the process would end capitalism, though not by failing. Success would produce large bureaucratic corporations in which innovation was routine and administered, would erode the social basis of entrepreneurship, and would create an intellectual class hostile to the system that produced it. Whether or not he was right, he was not a cheerleader.

Why incumbents lose to worse products

The mechanism is the useful part, and it is not incompetence.

An established business is organized around a way of doing things. Its people are skilled at that way, its systems encode it, its customers expect it, and its margins depend on it. All of that is an advantage, and all of it is an attachment.

A new entrant carries none of it. They can adopt an approach that is worse on the dimensions the incumbent competes on and better on one nobody was measuring, and serve customers the incumbent does not want. The incumbent's response — improve the existing product for existing customers — is correct by every internal measure right up until it is fatal.

This is why the failure is usually not stupidity. The decisions were defensible individually and each one deepened the attachment. That is the honest version of process debt at the level of a whole business model.

What to do with it

Assume your advantage has an expiry date. Anything built on a current way of working is temporary, and the question is not whether but when. A business whose only advantage is being good at the current thing is a business with a clock on it.

Watch what is beneath your notice. New approaches arrive serving customers you have declined, at prices you cannot profitably match, with quality you would be embarrassed by. They look like non-threats by every measure you use, which is precisely the point — your measures were built for the old competition.

Prefer advantages that survive a change in method. Relationships, reputation for judgment, accumulated understanding of a customer's business, and switching costs all survive a technology shift. Being efficient at the current process does not.

Be willing to destroy your own thing. The hardest and the only reliable defense. An incumbent that cannibalizes its own product keeps the customer; one that protects it keeps the margin for a while and then loses both.

For anyone running a small business the practical form is narrower and more useful. Ask what you would build if you were starting today with no clients, no staff and no systems, and then ask why you are not doing that. The gap between the two answers is the measure of how much of your advantage is attachment.
