This past Wednesday, Joanna Thurmann of Polycom gave a great Voice of the Customer presentation.
Polycom has 115K issues, 3K total users, 310 custom fields, 120 projects, and 70 workflows. This load has raised issues of search, security, scalability, etc. If this information sounds ‘close to home,’ please view the webinar in its entirety:

A big thank you goes out to Joanna for giving such an in depth and thorough presentation. She also provided her slides from the webinar: Voice of the Customer Webinar – Polycom.ppt.
Our next webinar of the VOTC series will be with Jon Hertzig of OpenCloud on 14 Jan 2009. Jon will discuss using Confluence for their developer community as well as product documentation. Atlassian’s own technical writer extraordinaire, Sarah Maddox, will emcee this event.
