Document, host meetings, buy food, drinks and invite co-workers to have "time off" during a "work meeting" every now and then, but really documentation and generate good excuses that necessarily does not blame other departments.

Document pain points is a big one, everyone says them, but not always are they fixed or prioritized. Something to fix those will work - like creating, documentation, sigh.

People skills and politics, not even technical. :(

That's nothing to be sad about, quite the opposite. The longer you work in this field, the more you'll realize skills that make people "senior" are not technical most of the time.
