DDLC

Document Development Life Cycle (DDLC) is considered as the complete life cycle of a documentation task. Software documentation requires a well-defined methodology for the successful completion. DDLC should encompass and go along with Software Development Life Cycle (SDLC) because both are parallel as well as intertwined.

The DDLC consists of

Project start up
Requirement analysis
Requirement Analysis is an important phase of the Document Development Life Cycle. In this phase the technical writer gathers the useful material for the project and understands and analyzes all the information of the project.

The process involves a lot of effort. Information is collected from various sources connected with the project, mainly with the Subject Matter Expert (SME) and the software developers. To learn the features of the new product, technical writers resolve all the queries and problems regarding the project with the help of SME and software developers. The earlier versions of the doucment, if exists, can also be reviewed for better understanding of the project. Technical writers also search related information on online libraries and from the company resources and gather updated information.

Technical writers must understand the software from the technical point of view. Technical writers must use and test the software product in various ways to get a detailed idea about it. They then list down all the queries and problems faced while studying or understanding the product. They are expected to do their homework and prepare questionnaires related to the project, before meeting and interviewing important people in the project. They may have to meet the people involved a number of times to arrive at a comprehensive understanding of the project. At the end of this phase a technical writer must have resolved all the problems and queries in terms of documenting this understanding for a specific audience. T
