If you work in an environment where you can get an answer to a question or a specific piece of information immediately when the need arises, this makes your life easier--at least, in the moment. If you couldn't count on this quick response time, you'd instead have to do more advance planning for your work, be more organized, and be prepared to put things aside for a while and turn your attention elsewhere while waiting for what you requested. All of this would make the day to day of your working life harder (even if it produced more satisfaction and a better outcome in the long term).
