2. What do the officers do?

This section will provide a broad overview of what officers are responsible for. Future lessons will be going more in-depth. If you're familiar with the officer roles, you can skip this. We'll start from Sergeant at Arms, and work our way up.

A useful framework for understanding officer roles is to find analogues for them in Star Trek. In Star Trek, you need a ship (or space station) for the crew to occupy, and you need people to maintain and repair these systems. Engineering does this role. Similarly, in a Toastmasters club, you need someone to maintain, setup, and tear down the room you use, which is what the Sergeant at Arms does. 

Next up, on Star Trek you have a department that protects the crew, its equipment, supplies, and so on from intruders. This role is handled by Security. In a Toastmasters club, you need someone to secure and track your funds. That's what the Treasurer does.

Now that your ship is secure, you need someone or something to save records of what the club does and take care of administrivia. This is handled by the computer as officers record logs and request reports. Similarly, the Secretary maintains club records, such as executive meeting minutes.

So you have people maintaining the ship, security, and record keeping; what's next? You'll need to communicate with not only your own crew, but also the outside world, whether hostile or friendly. On Star Trek that's handled by communications. Your club needs to be broadcasting to the world to make it aware of its existence and draw in new members. That's what the VP of Public Relations does.

Sometimes making that alien contact can sometimes be hazardous to the crew's health, which is why there's always highly trained medical staff on any vessel in Star Trek. They're responsible for the crew's health and well-being. Keeping an eye on your club's members and helping to familiarize new guests and members is what the VP of Membership is all about.

The main mission of almost any Star Trek series is to be explorers and be learning, which is what your club members should be doing as well. The first officer or science officer is a good fit on Star Trek as the former usually arranges duty rosters, and the latter provides information about planets, alien species, and so on. In your club, you'll want a good first officer in the form of the VP of Education to help arrange agendas and motivate people to reach their educational goals.

Finally, the linchpin officer of the ship (and likely what you associate Star Trek with)...the captain. They take missions from Starfleet, then use their discretion to guide their ship and crew to complete them. Your President is similar in that they have objectives from Toastmasters International that they need to guide the officers and members into achieving. 

This is, of course, an exceptionally broad overview. Later lessons will delve deeper into these roles.
