There are many businesses where shipping 20% later leads to ceding first
mover advantage and losing the game.
Are there? Can you name some examples? Because when I think of technology, first-mover advantage counts for very little. The first successful web browser wasn't NCSA Mosaic. It was Netscape. The first successful portable music player wasn't the Nomad, it was the iPod. The Macintosh long predated Windows, but Windows has by far the larger market share. Same with iOS and Android. Google was far from the first search engine. Facebook was far from the first social network. Amazon didn't invent e-commerce. In automobiles, Ford was first to mass production, but it was overtaken by General Motors by the 1930s, and they both were in serious trouble when the Japanese auto manufacturers, which didn't even really get going until after World War 2, arrived.So in which business exactly does shipping 20% later lead to "losing the game"? If anything, the real risk is in shipping a half-baked product too soon.
