You get what you ask for. We encourage you to be proactive and quick to seek answers. Ask and ask again until you’re aligned with the goal of the task you’re attempting to accomplish. If you disagree on a topic, it is your responsibility to explain why you disagree and share your views with the team.
The back and forth of discussion can clarify the different views, and concise writing of the core issues helps people reflect on what is the wise course, as well as making it easy to share your views widely. The informed lead on that decision has the responsibility to welcome, understand, and consider your opinions, but may not agree.
Once a decision is made, however, we expect everyone to help make it as successful as possible. Later, if significant new information becomes available, it is fine to revisit the topic. Silent disagreement is unacceptable and unproductive.
