What is a key component of a best practice approach to software documentation? Using complex language to impress stakeholders. Ensuring documentation is clear, concise, and accessible. Focusing solely on technical specifications. Minimizing documentation to save time.

Ensuring documentation is clear, concise, and accessible.

Why are user stories important in the specification process? They provide a narrative for developers to follow. They ensure only technical aspects are prioritized. They reduce the need for formal documentation. They are used solely for marketing purposes.

They provide a narrative for developers to follow.

Which best practice can help in managing changes in software specifications? Avoiding any changes once specifications are written. Implementing a formal change control process. Encouraging ad-hoc changes by developers. Limiting stakeholder input to prevent changes.
