Written communication takes various forms including memos, reports, letters, notices, and circulars. It creates a permanent record, allows information to be stored and referred to later, and ensures all recipients receive the same information. Written communication enhances an organization's image, is precise and explicit, assists with delegation of responsibilities, and provides necessary legal documentation. The document defines written communication, lists common forms used internally, and discusses benefits such as permanent records, easy distribution, and development of an organization's image.
