💬 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? 🗺️ Topic Map: The Change Control Lifecycle MES CHANGE LIFECYCLE ├── Change Request │ ├── What is changing? │ └── Why is it changing? ├── Impact & Risk Assessment │ ├── Manufacturing operations │ ├── Quality & Compliance │ ├── Data Integrity │ └── Validation status ├── Testing Strategy │ ├── Risk-based testing (CSA approach) │ └── Regression testing ├── Formal Approval └── Production Release ├── Deploy ├── Post-deploy verification └── Revalid...
