REMEMBER THIS • Real-time communication channels should be used sparingly. Time spent communicating should not come at the sacrifice of time spent concentrating. • Company culture matters. Changing group chat practices may involve questioning company norms. We’ll discuss this topic in part five. • Different communication channels have different uses. Rather than use every technology as an always-on channel, use the best tools for the job. • Get in and get out. Group chat is great for replacing in-person meetings but terrible if it becomes an all-day affair.
