Communication is such a nuanced thing. In our core senior group there is one guy who refuses to let us talk about anything remotely resembling an implementation-related detail if we're early in the high-level design stage, and it honestly shuts conversation down. I get his point, however at the same time a group of good engineers should be able to briefly and abstractly discuss the potential downfalls of a design decision while considering an implementation detail (say, using columnar storage to address some high-level requirement). Then, there's folks who communicate "well" in standups, meetings, design discussions, are cogenial, etc. At the same time they might be drowning in some technical debt they've taken on and no one understands it until they're 2 weeks overdue on a deliverable.
