Pity it's not possible to open-source execution. So many good ideas fail due to poor execution (these days, quite possibly a larger number are killed by birth by bigco's - that's still a 'failure to execute' though, in a certain sense).
To be fair, there is a lot more information and educational material out there on how to build new products more effectively, the last 10 years or so. It still takes time to learn even the basics.
