I got hired as a project manager to oversee the 5 programmers on a massive project once. Their previous “supervisor” was the owner/ceo with NO technical background for about 14 months.

Every single feature and block of code was written in 30% the time it should have been given. The ceo had no idea the technical debt he was creating until it was too late.

The day I came aboard any new feature or change that could be completed in 100% standard time needed 200%+ the standard time to account for the shortcuts taken over the previous 14 months.

It was a total shit show and a half.

The company shut down 6 months later.
