In package development, which practice is most aligned with centralizing changes and ensuring traceability?

• A. Tracking changes in each developer's local machine only
• B. Using a version control system as the authoritative source
• C. Deploying directly to production without review
• D. Keeping separate copies of code in each environment

Answer: (B)

Centralizing changes and ensuring traceability depends on having a single source of truth for the codebase. A version control system serves as that source by recording every change as a commit with who made it, when, and why, and by preserving the full history. With this setup, all work happens in a shared repository or well-defined remotes, making it possible to reproduce any past state by checking out a specific commit or tag. It also supports branches and merges, so features, fixes, and releases can be developed in isolation and then integrated while maintaining a clear lineage from the release back to the exact commits that introduced it. This centralized approach reduces drift between environments, enables formal reviews or approvals via pull requests, and simplifies rollbacks if needed. Tracking changes only on a developer’s local machine risks losing or diverging history, making traceability and collaboration difficult. Deploying directly to production without review bypasses governance and makes it hard to know precisely what changed or why. Keeping separate copies of code in each environment creates drift and fragmentation, breaking the ability to trace builds back to a single, known set of changes.
