In the tech industry where i work, graduates of management schools are always coming up with new (i.e the same old) ways to make good communication happen. Right now they’re back into “open floor plans” as opposed to cube farms, expecting people to collaborate simply because the walls are missing. It doesn’t happen that way. My current team is all in cubes but we instant-message and chatter constantly, not because or in spite of our office decor, but because we have good team chemistry. We work together well and enjoy working together.
Likewise, “agile” software development, where daily “scrums” get engineers together every single day to tell everyone else what they’re doing and why and so forth simply does not increase productivity just because of this enforced interaction. I’ve seen this approach succeed and I’ve seen it fail, and every time the deciding factor is the team itself. People who work together well will do so regardless of the structures put in place by management, and people who don’t, won’t.
You find the same pattern replicated in many areas of life. Successful relationships are not isolated facts but ongoing processes. You may have found your “soul mate” but if you don’t practice daily partnership and support, it’s probably going to go down the drain.
