AV integration is too broad for any one person to master. A single project can span audio, video, control programming, networking, acoustics, rigging, electrical, and construction coordination. Anyone who claims to be an expert in all of it is telling you something about their honesty, not their ability.
I am a subject matter expert in a few areas. Audio, acoustics, live event production, RF coordination. I have spent thirty years in those rooms, and I still do frequency coordination and system tuning on projects because I trust my own ear and math there. That is where my depth is real, and where I work hardest to pass what I know to the people behind me. It is not everywhere.
My network engineers know more about switch configuration and traffic management than I do. My programmers solve control problems I would labor over. My video specialists see things in a signal chain I would miss. None of that threatens me. It is the entire point of building a team.
The job of a leader is not to be the smartest person in every discipline. It is to know enough across all of them to ask the right questions, hire the right people, and get out of their way. Broad knowledge to lead. Deep knowledge in a few places to stay credible. Trust to cover the rest.
The leaders who struggle are the ones who cannot admit the edge of what they know. The team always knows where that edge is. Naming it yourself is what earns their respect.
Where are you the expert, and where have you learned to trust your team?
