In the last week, I have heard a number of claims that research supports the idea that workers on-site are more innovative than those who work from home. I remain skeptical. The notion that impromptu conversations with colleagues in the cafeteria are the core of innovation seems a bit simplistic; in my experience, they are just as likely to produce talk of better jobs at competing firms or last night’s “American Idol” winner. Besides, much of this “research” simply shows that workers who collaborate with others in loose networks generate better ideas. It doesn’t suggest that the best way to create new products and services is by isolating your employees in the silo of a single location.
