Abstract:

Most technical communicators create materials that help users perform tasks. Such task-based manuals, help files, web pages, or training materials are often expensive and difficult to write and maintain. Frequently, this is the fault of poor structure and process. Simply Written’s Clustar Method makes it cheaper and easier to create and maintain task-based documentation by emphasizing structure and process.
