Which of the following is a best practice in software development?

Documenting all code is a recognized best practice in software development because it enhances maintainability and understandability. Proper documentation serves several critical purposes: it provides clarity on the functionality of the code, enables easier onboarding for new developers, and facilitates collaboration among team members by establishing a shared understanding of the software’s structure and flow.

When code is well-documented, it becomes significantly easier to troubleshoot issues, implement new features, and ensure that the software can evolve over time without losing key information. Additionally, documentation can help bridge knowledge gaps that may occur when team members leave or when there is a long interval between updates, reducing the risk of knowledge being lost.

In contrast, ignoring user feedback, not following design specifications, and avoiding testing are practices that can lead to poor software quality, user dissatisfaction, and increased costs down the line. Such approaches undermine the software development process and can result in products that do not meet user needs or expectations.
