teamwork 團隊協力；群策群力；同心協力

* 和 collaboration 不同：

The new collaboration is not traditional teamwork at all. The difference today is that individual efforts can be harnessed on a large scale to achieve collective outcomes, like Wikipedia, the online encyclopedia written by 75,000 active volunteers and continually edited by hundreds of thousands of readers around the world who perform millions of edits per month. That would have been impossible to achieve without a new generation of collaboration tools.資料來源：Grown Up Digital: How the Net Generation is Changing Your World）
