I have a vaguely-relevant war story.
1998 - Huge business, re-writing some vital piece of the platform in the middle of Y2K. Contract coders are expensive but also the only available people to throw at this.
The architect had mapped out the entire system down to class/method level. They'd produced a huge list of classes and methods that needed to be built. So the company hired a bunch of contract coders to build said classes and methods, including your humble protagonist. We were each given a list of methods to write up - parameters, operation, expected output. We wrote them up, and ticked them off the list. We were not briefed on how they interacted. There were no tests that we could run. There was apparently no-one checking that what we wrote in the method actually matched the spec. This was before git, so version control was extremely rough, and also before JIRA (iirc the list was an Access database).
We all realised very quickly, like the first week, that this entire project was doomed. But we were getting paid a lot of money to do this, so we just did it. It got really boring really quickly. Every day we wrote a bunch of methods, and next day got a list of the next set of methods to write. The lists just kept coming, with no idea how long the master list was, or how the classes interacted with each other, or how the system actually worked, or anything.
I left after a month. The money was good, but the boredom was driving me insane.
I learned later from friends who stayed that the whole project was canned a couple of months later when it became obvious that this was a complete waste of money and would never work.
Whenever I see a project manager staring at JIRA instead of talking to their people or looking at the codebase, I'm reminded of this project. And your comment reminded me of that ;)
