Documentation
The Role of Documentation in the Systems Life Cycle
- After passing through the initial stages of the systems life cycle, the next crucial stage is Documentation.
- Documentation is a formal way of recording and explaining the internal architecture, function, operation, and the use of a system. It includes both Technical documentation and User documentation.
- Technical documentation is aimed at system administrators and support staff, it typically outlines the installation, maintenance and troubleshooting processes of the system.
- User documentation focuses on end-users of the system. It includes manuals and guides that help users to operate and interact with the system effectively.
Key Elements of Documentation
- Documentation should include a description of the system, detailing its purpose, functionality and the processes it undertakes.
- It also includes operating procedures, which describe how to use the system, including starting it up and shutting it down properly.
- Detailed guides on how to handle errors and problems in the system should also be included.
- Documentation must include backup and recovery procedures detailing how to protect the system’s data and restore normal function in case of a disruption.
Importance of Documentation
- Documentation provides crucial support and reference for both the system’s users and its technical support staff.
- Quality documentation is vital for the effective operation and maintenance of a system.
- It enhances usability and understandability, allowing users to get the most out of the system.
- Documentation can also assist in future system enhancements and modifications, as it provides a clear overview of the system’s original design and intended function. Therefore, it plays a decisive role in the ongoing life cycle of the system.
