Internal documentation is a form of technical writing in which instructions for creating, maintaining, and troubleshooting computer systems are recorded and preserved. It is used to provide a comprehensive, structured record of the execution of various tasks related to software systems and services. Internal documentation can be written in a programming language, as a set of commands, or in a natural language such as English.
The purpose of internal documentation is to capture the understanding and knowledge of all the personnel working on a project. It serves as an integral part of the process for developing computer systems and services. Furthermore, internal documentation is essential to maintain software quality and product continuity.
The main types of internal documentation include system design specs, user manuals, test plans and reports. System design specs summarize the capabilities and requirements of the system, such as its specifications, components, and functions. User manuals provide instructions on the use of the system, and how to get the most out of it. Test plans provide a roadmap of the system components and the associated tests. Finally, test reports show the results of the tests, errors encountered, and other such issues.
Internal documentation is essential for ensuring the integrity and security of a system. It helps maintain system reliability and accuracy. Consequently, it is important for every software developer to maintain proper internal documentation, as it may be required to troubleshoot issues and fixes reported. Additionally, it also helps to keep the development process streamlined and efficient.
Internal documentation forms an important part of the day-to-day work of a software developer. Without it, even the most sophisticated software systems can easily break down and become unreliable. Consequently, all software developers should strive to keep their internal documentation up to date and accurate.
