Don't rely on a single product to guide your team. That's why you have a team leader. They are in charge of making sure you have the most effective tools at your disposal so your team can work efficiently. Multiple products that they know work well enough together that your team can benefit from using them in conjunction with one another. Sometimes one component of the system won't work well with others. The team leader replaces it; and life goes on.
Use Google Docs or something similar to easily share documents and resources.
Use Git or SVN to have a repository for your project if multiple members write code that's updated regularly.
Use the phone to call someone when it's urgent or text them if you can wait for a response. Still feel free to email people as an alternative method of communication. Use Skype, or just about any other instant messenger. Don't rely on just one thing.
Rely on your team leader, that's why you have one. Can't reach someone or somebody isn't putting in their fair share of work? The team leader ultimately takes care of that, whether by removing the offending member or reprimanding them.
Specifically, our team uses Git to access a repo hosted on ProjectLocker. PivotalTracker helps keep our features, deadlines, and bugs prioritized; and we're looking into using Trac for bugs and issues. We use Google Docs to share resources. We email each other constantly; have each other's phone #s; and sync up via Skype at least once a day. There are a few hiccups here and there, but you learn to roll with it and keep on going.
One of the principles we have here at Bing is to constantly experiment and learn. We do this to ensure we are keeping pace with new social and technology trends, and can continue to deliver great value for our customers and advertisers.
As part of this "test-and-learn" mentality, we will be retiring the Bing cashback feature, which means that the last day you can earn cashback will be July 30, 2010.
