Information Workplace - What is it?

When I explain what the Information Workplace concept means, I use the following compact definition:

An Information Workplace offers the user data and applications that are tuned to the user's current task, role, context and his favorite and available tools.

User interface meaning: one or a collection of user interfaces (possibly multiple devices) that support the user in performing his current task.

By context, I mean all influences on the user performing the current task, e.g. location, device, date & time, role, et cetera.
