From DeveloperWorks, Managing tasks and business processes using WebSphere Business Space:

Learn how to create WebSphere BPM V6.1.2 Business Space dashboards using
the run-time artifacts from the WebSphere BPM V6.1.1 Clips and Tacks tutorial.
You’ll create a business space to manage the tasks and business forms input,
run some processes that use forms, and finally create a business space you can
use to monitor the process and tasks.

A good resource if you’d like to know more about what a ‘Business Space’ is.
