This is what Jack Vinson says about Tame the Flow:

[…] a way to combine approaches that make the best of several worlds. Use ideas borrowed from Critical Chain to monitor the overall health of a delivery project. Use the ideas of Kanban or Scrum to manage the flow of work around stories or story points (within software development - I see application outside software too). Use ideas of Drum Buffer Rope to think about improving the flow of a Kanban board. And throw in a healthy dose of other approaches and thinking to help think about what is happening in an organization.
