Warner Music's ADA-centered strategy - in which they only distribute smaller indie acts until they reach a certain level of success and then sign them - is very similar to the "make or buy" and "own or lease" scenarios covered in this unit. What are some relevant and irrelevant costs associated with the decision to sign an act (make/own) as opposed to just distributing one (buy/lease)? Identify at least 2 relevant and 2 irrelevant costs.
