@Natasha_Jay how did they caught it by accident? Isn't that one of the first steps you do with data to check if it actually works?
So they could have just hired some random who will throw dice and even that would be a more sound business decision because at least then you have someone who takes accountability?
All these people worked with the data and not once did it click that the data doesn't align with their previous data?
