Michael Hyatt has a free productivity assessment tool that provides “a free analysis of your overall [personal productivity] score and a breakdown of the productivity areas you evaluated.”
A followup email provides a short set of tips for improving, and the analysis page that displays after the survey is completed provides access to sign up for a free webinar on the “7 deadly sins of productivity.” I attended the webinar recently, and it does provide a good number of suggestions revolving around focus as a primary key to productivity.
The webinar then offers attendees the opportunity to sign up for a paid productivity course with still further content. But, the free elements contain a good amount of helpful information themselves.
