1. Business documents range from emailsto legal agreements, so it is not necessary, for example, that a professional writes an email (this means that everybody can do it)
2. Business documents must have many drafts in order to avoid mistakes that can ruin the writing completely.
3. School writings assignments may have a specific structure, while the business documents may not.
