Welcome to your interview.
The question is on your right: Interpreting SPI and CPI. 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 are the Schedule Performance Index (SPI) and Cost Performance Index (CPI), and what does it mean if SPI is 0.85 and CPI is 1.15?
