LEARN LIKE A SCIENTIST: YOUR FIRST EXPERIMENT (JABE BLOOM) - LKCE13
A3, PDCA and the Build Measure Learn loop (to name a few loops) are all informed by experimentation. Kanban embraces the scientific method explicitly; "Improve Collaboratively (using models & the scientific method)" and Lean implementations can be more effectively supported by a sound understanding of the philosophy of science and proper experimental design. This presentation will briefly explore the basics of the scientific method, including deductive, inductive and abductive logic, probability, parsimony, and hypothesis testing. Through a series of group exercises, the audience will grapple with the concepts and return home ready to create an execute their first scientific experiment.

Wherever possible there must be independent confirmation of the facts.

Arguments from authority carry little weight (in science there are no "authorities").

Try not to get overly attached to a hypothesis just because it's yours.
Quantify, wherever possible.
If there is a chain of argument every link in the chain must work.

Ask whether the hypothesis can, at least in principle, be falsified (shown to be false by
some unambiguous test). In other words, it is testable? Can others duplicate the
