Hi there,
You're starting to get into "solve the case for me" territory. You can absolutely ask how this technology/innovation is going to improve the product (i.e. across what traits, etc.). From there, yes you are expected to think through how those improvements/innovations will actually result in new benefits.
In regards to saving time, it could do both right...if I redesign a product to save time in terms of aging my wine, well, that means I can produce more wine and make more money. However, if it saves time and let's me bottle each wine more quickly, that allows me to cut labor costs (I'm a winery meaning my land/# of grapes is mostly fixed).
Think through these problems critically...that is always the expectation! :)
