Office Hours Follow-up: What does your event team look like?

We talked a bunch today about different ways to organize a team, different roles, and how folks take on those roles. Here's how our event is organized: 
Note: Our event is 1-2 times a year as a single-day, conference-style event. Our last event had registration over 750 and had over 360 people onsite the day of. 

Our leadership group is 3 people - the same three that created the organization and sit on the board. 

Person 1 (board member) - Does the money stuff: Invoicing and payments, tax filing, managing accounts, etc. 

Person 2 (board member) - Overall event coordination, Sponsor coordination, communication, venue coordinator/contact, website management, Eventbrite, some Community Day page updates, acquires giveaways for closing gathering, and event budget (and needs to delegate more...) 

Person 3 (board member) - Taking a less-active role but continuing to provide leadership input and decisions as well as helping out in areas they recently managed. 

Person 4 (non-board) - Managing food for the event and speaker dinner arrangements. (New) Taking on Speaker coordination. 

Person 5 (non-board) - Venue/room needs day-of: Working with in-room tech and posting room schedules

TBD - Volunteer coordinator for prep time and day-of activities 

TBD - Registration / Welcome team coordinator

TBD - Photographer to capture event for future materials

Our content team has been each of the folks listed above when reviewing session submissions. 

Branding was handled with an external (volunteer) resource. 
Marketing has been ad-hoc but could use some organization and improvement. 

Note: All folks listed do plenty of other things as needed. :) 

We're in a bit of a transition right now as roles change and there are always areas to improve...
