SAP StreamWork, from the well-known enterprise software giant, is a team-building and team-coordination tool. It lets a business bring together both employees and people outside the company to work on a task and provides communication features to help them work together. It also hooks into SAP business intelligence software as well as third party collaboration apps. The SAP StreamWork mobile application (free for the iPhone, expected soon for the BlackBerry) lets you create StreamWork activities, add participants, upload content, and establish action items. You can also contact teammates via their StreamWork profiles to call or send them an email.
