The biggest thing is to not be afraid to ask questions. Even in meetings where you may not be quite as knowledgeable about the subject, ask questions to learn more, you may notice something as an outsider or just learn something new. I'm not just talking about meetings, ask your manager or other team members to shadow other members for a day and gain some insight from more than just your team. Reach out to your mentor, they can be an excellent source of information as well. Ask questions, there are plenty of intelligent people at Cerner and they are more than happy to transfer some knowledge to a potential new member to the team. As mentioned earlier, I would also recommend going on the Data Center tour, that is a truly amazing experience.
