Which practice strengthens the ability to reproduce results in a project?

• A. Deleting version history.
• B. Avoiding documentation.
• C. Writing a clear, detailed plan with steps.
• D. Keeping changes informal.

Answer: (C)

Reproducibility in a project comes from documenting the exact steps and sequence used to reach results. Writing a clear, detailed plan with steps provides a concrete recipe: it specifies what data to use, what methods to apply, the order of operations, parameter values, and the decisions made. With that plan, anyone can redo the work and arrive at the same results, or understand where differences might come from. This kind of documentation and predefined workflow makes the process transparent and verifiable.

Deleting version history removes the record of what changed and why, making it impossible to trace decisions or revert to previous states. Avoiding documentation leaves ideas in memory only, which is unreliable. Keeping changes informal means there’s no standardized process, so steps can be skipped or altered unintentionally, breaking reproducibility.
