> It's quite possible to get lost in the weeds planning stuff with no forwards motion. It's also possible to make really, really expensive mistakes by plowing forwards.

An excellent point which is often omitted in such articles. Finding the right balance between careful planning and plowing forwards is of great pertinence. I look at planning as a risk minimization exercise. Once risks associated with failure are minimized, I can then forge ahead. Hence, the time planning is a function of the project's risk profile, which can vary drastically.
