It sure does. But using it within software development (not automobile) in an agile manner does not.
Unless you're proposing that the only thing that exists in all of agile is scrum itself? (Which simply does not exist in the Manifesto)

I'm sorry you're frustrated. From the field, I've seen a lot more bad implementations of agile help people at least get organized, than I have the same from merely urging people to do the same. Only one effort is changing the system.
Otherwise, it's just Deming's red beads.

The delay in adding the new hire to the rotation because they have to learn the oddball system.
The cognitive load of being on call for something that is barely tested or maintained
The activity to patch and deploy something that is hard to build and scarcely tested.

Tue Jun 21 17:18:56 +0000 2022With recent bear market dips, it’s a good time to shut down marginal products rather than maintain those which generate little revenue/are not the future of the company.
Often finance sees revenue, and some bills, this is what they don’t see. 🧵

The time it takes to run security scans and tests just so they are documented, not because they will be fixed.

The load on the project manager who still has to report on the status of the marginal product because if she does not, people might forget that it exists.
The additional attack surface the company is vulnerable to for a product that barely makes a profit.

The time customer success spends on calls for the marginal product instead of developing stronger relationships with high value customers.
