15. 美國聯邦調查局(FBI)案例
$575 million dollars wasted on the first two
attempts at the project
Scrum Studio was set up in the basement of the
Hoover Building
Staff reduced from 400 to 40, and in 1 year
and $30 million, they were code complete, at
a cost savings of more than 90 percent
If an organization like the FBI can do this, why
can’t yours?
