Q

What are the activities of the do step?

Q

What are some questions to ask in the study step?

A
  • What do the data tell us?
  • What did we learn?
  • What went right, and why?
  • What went wrong, and why?
  • What was unexpected?
  • Is this change going to get us to our goal?

A

to take action based on what you learned in the study step
