That is a good point... and gets back to the chief programmer of the MMM surgical team.

One of the aspects of having a chief programmer (and there's another HN article making the rounds on heroes for projects) is that they're able to conceptualize/structure/design an entire application or module.

A chief programmer, doing a "this is how we're doing it" and with all the parts in their head and working to that end will have better overall "idea to deploy" performance than someone who is given the task of "do X" and may have to come back to it again to reconcile their implementation of X with the design of the system and its goals.

The way to resolve that is to get everyone who is working on it on the same page for the design... and that takes meetings leading to the issues with adding more people to a project will make it later.
