I think you hit it on the head. I'd break down the 75% a little further in my case: - 25% Poisonous people in key architectural/infrastructure positions who actively make it as difficult as possible to communicate. - 15% "Mea culpa". I fail to clarify or make an assumption due to busyness, lazyness or missing something. - 25% Folks who do not take initiative to engage in conversations at the appropriate time. These folks typically pop up with 11th hour critical path problems. - 35% General nonsense: People incapable of writing english, etc.
