What dooms software projects? Everybody quotes the opening lines of Anna Karenina at some point. You know the one. It’s the bit about happy families being all alike in their yaddayadda-blabla and how unhappy families are all unhappy in their unique blablabla.
There’s plenty of stuff in Anna Karenina you could quote, but I guess most people give up on it before they get to the second half. Which is a pity because it’s a good book.
