The Register has an interesting article on telecommuting stats.
With Telligent, I'm working from my home office currently. Initially, we're going to try to go with a true distributed model with most of our employees. I think this is great because it doesn't limit our hiring geographically, and I would contest that the technology is there to easily collaborate still.
We use things like SourceGear's Vault for our distributed source control. IMHO, that's still Vault's biggest advantage (among many others, of course) is the ability to easily create a source control solution that can be used world wide with little problems, and still amazingly fast speeds.
We use Countersoft's Gemini for issue tracking across all of our projects. Though, I have a serious eye on Sourcegear's Dragnet product that's in the works. I'm hoping Eric can hook me up with a beta! :-)
And, of course, IM is priceless. E-mail is good, but IM is better. Nothing beats immediate gratification.
<p>I was also working from your home once and able to do <a href="https://reqtest.com/testing-blog/test-management-tools/ ">test management</a> even at home because i was using software testing web based app instead of excels. So its easy to access anywhere instead of 100's of excels.
