    An excellent explanation of not only the GPS but the way to conduct and access reasonable exhaustive research according to the BCG standards. His references to BCG definitions and standards were very helpful.

    It really helped that Gary talked at a reasonable speed and enunciated, as I was trying to take in every single word. But even so I need to watch this again as I’m unfamiliar with some of the terms used.
