This is silly, they didn't spend a year trying to crank out the right code, they spent a year not being aligned, disagreeing on approach, getting people to commit, support from other teams providing necessary integrations or platform etc. - Claude didn't help with any of that, it just did the code part, which wasn't the problem in the first place.
This mirrors our experience with our big customers. Minor changes requires countless meetings with a dozen people and nobody takes charge, everything has to be repeated at least three times because people rotate while this circus goes on and so on.
In the end we finally get the people who know what's up involved and it results in a brief meeting and like an hour of writing code and testing.
One of our strengths is that we've all been here so long. We know these large customers way better than they do, because we still have the dev and the project manager that worked on the last thing, even if that was 6-7 years ago. We've literally had a large Fortune 500 customer call us and as how their systems worked, systems we don't even integrate directly with. And we could inform them, since we had retained that knowledge from a project some years ago.
So yeah, the code is usually never the problem.
