Isn't the big picture just maximizing income for the company while minimizing expenditures? This is the only purpose of everything but charities. Products are only for transforming into money.
My "big picture" was not so big. It's just to get enough context to do my "mundane" work well. I forgot to say that I'm only a mid-level engineer. For instance, to give good opinions/high-level solutions during ticket refinement sessions, realising when a ticket is not clearly written and things like this.
Also, there's always this debate about the level of detail that goes into a ticket. Lots of detail makes refinement sessions take ages (and they aren't the place to "solutionize".
However, tickets with fewer details (just the business outcome), can be challenging as we may not yet know all our service's logic or we may not know enough about the organisational structure of our company (for when we need to interact with other teams with different competences).
