Analyzing the value of Risk Management
I believe that it's worth an hour of the PMs time. The first 35 minutes (roughly) with the presentation itself, prior to questions, is the most valuable content. The recording quality isn't great (a fact repeatedly noted in the recorded session's chat dialogue).
Weis' presentation underscores the importance of the Identify Risks process in management, if you want to have the outcome of a solid Risk Register with acceptable variance between documented risks and risks encountered in the project.
