Your marketing dept is more than just buttons. It is what will define the image of your team.
Some of the things they should be doing are:
Making brochures that describe who your team is for potential sponsors and another one for potential recruits.
They need to be writing press release for the media in your town, introducing the team and invited them to whatever regional you are going to. You also need to follow up with how your team did at the competitions
They need to come up with a sponsor packet which should include: an intro to your team, a mission statement, some facts about your team and FIRST, Sponsorship levels, a business plan and other needs, ie: Mentors, free food, in kind donations.and a schedule of all your events.
They need to send invitations to all your local, state and national representatives for the Regionals and include a brochure explaining who you are
They need to come up with a great pit design that shows your teams personality
They need to be working on the chairmans award and the woodie flowers award
When the time gets closer they need to have a robot trading card with a pic of the bot on the front and all the stats on the back to hand out at Regionals.
They need to work on packets to hand out to judges with all the pertinent info about your team: include your business plan, a copy of your chairmans award essay, a list of any outreach events you have participated in, a list of any teams you mentor, your brochure, your robot card, your team handbook, your sponsor pack, an explanation of your design process and anything else you can think of.
You need to make sure your t-shirt design, your pit, your robot, your spirit supplies and anything else associated with the team works together to show the personality of your team.
