Classical process organization divides team into groups according to their responsibilities (biz, dev, qa, ops). Building walls between those groups forces sequential communication: one team finishes their part then passes result to the next team. And no matter how efficient is the process within single group, this could lead to higher latency when reacting to bugs or changes.
