Good article. The Valley preconception that great execution on a bad idea will fix things always rang a bit hollow to me. Seems to me to be the most common cause of failure - people build great stuff for problems which don't exist.
I think the idea (hah) there is not that great execution fixes a bad idea, but that a great team will discover that the idea sucks and move away from it while executing. Great execution on a bad idea is not great execution.
True but harder than it sounds in practice. People (1) fall in love with ideas for long times and (2) are worried about being labelled (or seeing themselves) as quitters.
