Dependant partly on stage of company and stage of product, however... Consider asking how many products they have successfully canned. Not launched. Killed. When you’re a PM launching products everyone from the investors and CEO down is your friend. When the time comes to kill a product, nobody want to know. Product Management is the job of managing the product through the product lifecycle. Concept, development, launch, iterations and enhancement, maturity, and yes... eventual migration, retirement, and burial. If you are at a large and mature company a PM may be required to retire more products than he launches. Both ends of the product lifecycle are important.
