Why I built this
Apparently, one of the companies I used to work for doesn't have something like this, or should I say they want to have it, but the effort that they did estimate was too much. And, no one has the guts to be in charge. I was one of the developers who worked on the project that spans across a lot of teams, and not to mention there are branding and styling changes involved. It was a pain in the butt to start the project in the wrong way; the project ended up unfinished, and it costed at least hundreds of engineers' time for 3-4 months. Compared to the cost, doing the right estimation at the beginning seems minimal.
Well, in a large company, doing things technically correct is probably the last thing to bring to the table. 🤷♂️
