I want to encourage this trend and get more teams to a Quantitatively Managed state of maturity. Alisson Vale and Phidelis are definitely there - even though they aren't using control charts.
(2) Classes of Service and Risk Management are the big important topics going forward. Dean Leffingwell's language of "allocate rather than prioritize" resonated with me and better articulates what I'd been saying about setting WIP limits on classes of service. Lots more to come on this topic going forward...
