Audio Video Ministry Documentation

This context defines the document types and core documentation language for Cleveland Baptist Church’s AV ministry. It exists so the ministry’s docs use consistent terms as the documentation set grows and so future AV leaders can inherit a documentation set that is structured for real operational handoff, not only volunteer orientation.

Relationships

A Landing Document links to one or more Room Overviews
A Landing Document can include a Discipline index that points back to Room Overviews
A Room Overview can link to one or more Volunteer Role Guides
A Cross-Room Reference can link to multiple Room Overviews and Volunteer Role Guides
A Cross-Room Reference can also serve as an Operational Reference when a future leader needs to understand a ministry-wide system
A Room Overview can include one or more System Diagrams
A Room Overview describes one or more Operator Positions
A Room Overview describes one or more Signal Flows
A Volunteer Role Guide depends on exactly one primary Room Overview

Example dialogue

Writer: “If Audio volunteers serve in multiple rooms, should we make one big Volunteer Role Guide?” Domain expert: “No — keep the room-specific Volunteer Role Guides authoritative, and only add a Cross-Room Reference if a shared pattern needs extra explanation.”

Flagged ambiguities

“guide” was used to mean both volunteer-facing instructions and deeper technical documentation — resolved: use Room Overview for the deeper technical doc and Volunteer Role Guide for task-focused operator instructions.
“audio” can refer to both a Discipline and a specific room assignment — resolved: use Discipline for the ministry-wide category and Volunteer Role Guide for the room-specific assignment.
“FOH Audio” was used to mean both the house-mix source and the Livestream Audio Console’s fallback operating mode — resolved: keep FOH Audio for the house-mix source and use FOH Source Mode for the fallback mode.
“stage display” and “confidence monitor” were used for the same concept — resolved: use Stage Display.
