My best example was a 28 day project. It was a tight budget and deadline so I was to hop on, get it done and on day 28 never spend another dime on it.
There was no room in the budget for CI/CD.
Result: Others in the company wanted to do more review (even if the project was done, closed and working) so who would pay me to do this work. I agreed to more reviews if they would find the money. Yup, the folk that wanted more reviews on a project they weren’t involved in didn’t come up with the money.
The project was a remote control dongle. Finished in 28 days and never needed updates. A classic example of where you don’t burden a project with automation etc.
