💬 In Plain Words: Once a Manufacturing Execution System (MES) is validated and running production (like batch B10025 ), you cannot simply edit the software's code because "someone asked for a new feature." Change control is the strict, governed process used to evaluate, approve, test, and document any modification. Before touching the production environment, you must ask: What could this change break? Does it compromise data integrity? What requires re-testing?
