@dave -- spot on re: innovation
>> There was one major area where telecommuting was shown to hurt enterprises -- innovation. Innovation relies on information exchange, and information exchange, you will remember, is one of the areas in which you need a really good plan to make telecommuting work.
In addition to larer systems, there are mobile-based apps like SLACK and others which are hanging around. Sometimes there's no substitute for being there when it comes to brainstorming, but at least with collaboration systems a company can have access to thought leaders and consultants who might otherwise never be on site, except at great expense, and who can help with innovation.
