There's a book about Germany working on the atomic bomb from about 10 years ago. One thing that I always stuck in my mind was that the Nazis had several different programmes, run by different organizations. I remember at least three, Wehrmacht, SS, and Post Ministry (I know, this is kind of WTF). All of these organizations actively competed against each other over a very limited amount of resources, in particular heavy water and fissible material. Of course that won't produce meaningful results if you're being sabotaged by other organizations in your country.
