What stage of the SDLC focuses on the written code and documentation?

The development stage of the Software Development Life Cycle (SDLC) is where written code and documentation are the primary focus. During this phase, software developers take the design specifications created in the earlier stages and start writing the actual code that brings the software to life. This process involves translating design documents and specifications into a programming language that the computer can execute.

Furthermore, documentation is also a crucial part of the development stage. This includes not only the code itself but also comments within the code, user manuals, and technical documentation that provide guidance for future maintenance and updates. Having well-documented code is essential for ensuring that other developers can understand, maintain, and enhance the software in later stages.

By concentrating on creating the code and robust documentation, the development phase sets a foundation that facilitates effective testing and ultimately leads to successful deployment and maintenance of the software.
