How do I see ways to make the whole workflow faster?

You do your own tasks well, and that focus is a strength. Seeing the whole flow feels beyond you because you have trained your eyes to watch your own hands, not the path the work travels. That is a habit, not a limit, and habits can change. The people who spot the big improvements are not smarter. They just watch differently. They notice where work piles up and waits, where someone redoes what another already did, where a thing gets carried back and forth for no reason. Waiting and repeating are where the time hides. Start small. For one week, notice the moments where you are stuck waiting on something or someone. Write them down. Those pauses are clues to where the flow breaks. You do not need to fix the whole system at once. You just need to start seeing it, and that begins with watching the waiting.
