Not Aligned. Definitely, Not Aligned
Introverts and most people would not make a peep in this kind of environment. Whether an All Hands or a Summit or something of that scale, silence does not translate to agreement. A more personal and “in the field” approach will suit you better if you seek real alignment.
Navigating feedback takes a lot of work as a leader. You are there to make the tough calls, not abdicate responsibility. Conversely, you must gain inclusion to have lasting change, so feedback is necessary.
Learning: Leaders who assume feedback will come from the dynamics of large groups are likely not seeking feedback at all.
