Few questions asked regarding metric development:

1. SQL queries
2. Imagine HBO has a studio which goes out in different locations and films movies. There are tons of people like principal cast, hair & makeup, sound, lighting, photographer etc and 100 more categories of people involved & costs associated with each of them.. what metrics would you consider for this situation?
3. How do you come up with a metric(s) that describe the cost of producing content by location?

Any thoughts on Q3 and Q2?
