Meetings are sometimes held around conference tables. In a meeting, two or more people come together for the purpose of discussing a (usually) predetermined topic such as business or community event planning, often in a formal setting. In addition to coming together physically (in real life, face to face), communication lines and equipment can also be set up to have a discussion between people at different locations, e.g. a conference call or an e-meeting. In organizations, meetings are an important vehicle for human communication. They are so common and pervasive in organizations, however, that many take them for granted and forget that, unless properly planned and executed, meetings can be a terrible waste of precious resources. Because of their importance, a career in professional meeting planning has emerged in recent years. In addition, the field of Meeting Facilitation has formalized with an internationally-recognized "Certified Professional Facilitator" designation through the International Association of Facilitators (IAF)
