In genealogy, charts are certainly needed for their brevity and organization, but a narrative expands information into allegory and stories into fables. Good composition involves the reader, forces them to think, to react, and to care about the subject. Communication is stressed in almost every business discussion, between company and client, or employer and employee. Anyone who has ever tried to program a VCR knows the importance of clear instructions. I must be able to speak to my audience at their level of knowledge to help them use our product.
Proper composition facilitates communication between the teacher and user.
When a company needs to inform its employees of new policies, proper expression can mean the difference between a good working relationship, and employee protest. Recently, executives in my company tried to describe the working atmosphere they wanted to establish in a certain department. Employees were infuriated and began a campaign of angry letters. The vice-president who wrote the offending memo immediately backtracked. He was forced to apologize, to assure employees that management did understand their problems, and to try to re-state his original point.
