There are two problem-solving approaches:
1) identify a problem that you want to solve, then find a method that will solve it
or
2) pick a method you want to use, and go hunting for problems.
The second way is the stupid way, so it shouldn't surprise anyone that it's the default method in tech.

When you have to manage many inter-team dependencies, accurate* estimates are critical. Since such estimates are impossible, this argues against having to manage many inter-team dependencies.
* accurate = fixed cost, scope, & time
