Web-Scale Human Task Management

Today, many professionals work on several projects in different teams at the same time and manage their task in these projects manually or with the help of a task management system. Business portals in larger companies typically provide some kind of task management support. But often they lack facilities to manage tasks beyond organizational boundaries and need technical support by IT departments. To overcome these limitations, especially loosely coupled teams make extensive use of emails and forgo explicit task management features. As the usage of web applications in all areas of life increases and thus more and more tasks are performed online, new solutions for web-based task management have become necessary. In this paper, we determine requirements for managing tasks in distributed environments without any central supervisory body, and identify related research challenges.
