Another element in recruiting a strong committee is to set specific goals and be clear about them upfront. Without clear goals the committee members will not know what's expected of them. Give them the expectations in writing. It's easy to create a one-sheet flyer on event or organizational letterhead with a few bullets outlining the expectations. Make sure to include a give/get fundraising goal, expectations regarding adding names/contacts to master prospect or mailing list, meeting calendar, and anything else you may ask of them. Use a tracking spreadsheet if necessary and share that within weekly updates.
Here's a start to recruiting an effective committee for your next fundraising event.
Recruit from your network. Start with your Board. Have Board members as the nucleus of the committee and charge them with recruiting others. Approach current donors. Reach out to event attendees. Create a wish-list of executives you'd dream of having on your committee and work to connect to them. Continue to build on the committee and elevate the expectations year after year.
