There's a few comments speculating about fraud, but they're way off on the timeframe. I was approached about this project like 7-8 years ago. It's probably been in development the whole time.

1k * 250 * 8 * a team size of 20 is about 40 mil in salary for engineering, could be low, add on their $12M testing, $4.1M just for the design (vintage Deloitte), some cloud cost blowouts and a bunch of dickhead managers and scrumlords, plus the putrid enterprise-grade 3rd party map/data system they've gone with, I bet that wasn't cheap. All up it's in the right ballpark for a typical well-intentioned trainwreck consulting project.

Wouldn't be the first project to blow out because of a bunch of enterprise Typescript, Java and C# devs that can't deliver anything.
