Welcome to your interview.
The question is on your right: Measuring Success of Changes. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
What metrics or data points do you look at to determine if a newly implemented system or process change was successful at Insulet?
