What is change control?

• A. A Casual Note to Suggest Improvements
• B. A Routine Budgeting Tool
• C. A Technique for Rapid Prototyping
• D. A Formal Process to Manage Modifications to Processes, Equipment, or Procedures to Maintain Safety and Quality

Answer: (D)

Change control is a formal process for managing any modifications to processes, equipment, or procedures so that safety and quality are preserved. It means changes aren’t made on a whim; they’re requested, reviewed for risk and impact, approved by the right people, implemented with proper documentation, and then verified and tracked to ensure they achieve the desired effect without introducing new problems. This structured approach helps prevent unintended consequences and maintains consistency and reliability.

Casual notes, budgeting tools, or quick prototyping don’t provide this level of oversight or documentation, which is why they aren’t the right fit for describing change control.
