alt Hacker News>I wondered, “Who is this feature even for? Who will use it?” No one on my team knew.
I think there's another key here - Don't assume someone else knows something. If you don't know why something is done some way, find out who does and make sure they do. I've been in so many situations where the organization gets complex - person A is loaned over here or person B is working on project X because team Y needed feature Z. So frequently you'll find out that core assumptions have been made because everyone involved was only half-involved and either kind of assumed someone else was taking care of it, or (more frequently) knows the assumption is wrong but is choosing not to say so for political reasons.

I sympathize with keeping one's mouth shut for political reasons. Having a boss who angrily shouts at anyone who dared use their own brain and offer an idea, I learned to keep my mouth firmly shut even if i saw countless problems coming down the road.
When I was in the Marines, we had a rule of thumb that every Marine needed to know their own mission and the mission of units two or three echelons above them. So individual Marines needed to know their mission, their platoon's mission and their company's mission. Company commanders needed to know their mission, their battalion's mission and the division's mission. More specifics for echelons closer to you.
This is complicated by the fact that Marines deploy as MEUs, MEBs and MEFs [1] which aren't "pure" echelons, but it's a rule of thumb and guiding principle more than a hard and fast requirement.
I've ALWAYS been annoyed by engineering organizations that don't think developers at the leaf nodes of the org chart need to know what's going on. Devs may not do anything with the info, but letting people in on what's happening seems to send the message that "management thinks you're important enough to hear what we're working on" and every now and again, individual devs need to make decisions that depend on these more abstract / higher-level goals.
