Since I work from home 80% of my time and the rest is reserved for meetings with clients (1 day). I found this article very interesting:

It warns CEO's or managers to consider 6 questions to answer when considering telework:

1. Is full-time telecommuting a smart decision?
2. How will you define and measure performance?
3. Will creativity suffer?
4. How will telework affect collaboration?
5. What about employees "left behind" in the office?
6. Do you have an exit strategy?

Overall it's an excellent summary! If you're thinking about offering telecommuting plans or asking your boss to work from home, you'll enjoy the read.

In my field (software development), I see more and more businesses offering telecommuting plans to their tech employees here in Montreal. Why? Their technicians call me from home! Most of the time, they offer 1 day (which turns out to be friday).
That seems to fit with:

"Still, he won't allow anyone to telework 100% of the time, except in rare circumstances, because he wants to keep informal communications flowing. "That's the kind of relationship I think we'll see more and more of," says Cromwell. "Not somebody telecommuting 100% of the time, but rather creating situations where someone will work from home one or two days a week."

And I couldn't agree more, when building a corporate culture, you want your employees to "need" to come to the office. Offering them a day or 2 to work from home should be seen as a bonus where they can reserve time for tasks they 'know' they can get done from home.

More then 2 days per week, hire a subcontractor, not an employee.

If you're a small team of professionals (2-5) like my company (Goldeneye Solutions) - it's a different issue in the early stage where telecommuting 80% saves time & resources.

It's also very important to use proper tools to collaborate,

All that said, I'll definitely keep the points in article in mind as I hire more employees.
It would be interesting to see how medium or large companies in Montreal are coping with telework?
