Change Control is the disciplined process used whenever equipment is updated. It requires documenting what will change, why, and how it could affect safety and performance, plus risk assessment, approvals, a tested implementation plan, validation, and updated procedures and training. By moving updates through these steps, problems are caught before they occur, safety is preserved, and quality is maintained because the modification is evaluated, tested, and traceable. Random Modifications ignore risk and standards, which can introduce unexpected failures. Bypassing approvals skips essential checks that protect safety and quality. Halting all work stops progress and isn’t a practical way to ensure safe updates, since a structured, approved process is needed to implement changes safely and reliably.
