The document discusses the Document Development Life Cycle (DDLC), which is a sequential process that technical writers use to create well-structured technical documents. The DDLC includes requirements analysis, project design, content development, editing, publishing, and content maintenance. It aims to establish a baseline methodology for creation, ensure documents are well-defined and structured, and improve productivity. Each phase involves gathering information, designing the document structure, writing content, reviewing for errors, publishing the document, and later maintaining and updating it with new information.
