9. Corrective Action and Preventive Action – Validation Plan for Computer System of UV:

No.	Identified Issue	Corrective Action	Preventive Action	Effectiveness Check
1	Incomplete or inadequate validation plan	Prepare, review, and approve a complete Validation Plan covering scope, responsibilities, validation approach, qualification, acceptance criteria, and deliverables.	Establish a controlled CSV procedure requiring an approved validation plan before qualification starts.	Verify approved plan is available and all defined deliverables are completed.
2	Incomplete Risk Assessment	Perform documented risk assessment for hardware, software, data integrity, security, backup, and system functions.	Make risk assessment mandatory before IQ/OQ/PQ execution and review it after major changes.	Confirm identified risks have appropriate controls and no critical risk remains unaddressed.
3	Incomplete IQ/OQ/PQ	Execute pending IQ, OQ, and PQ activities against approved protocols and document results.	Use qualification checklists, predefined acceptance criteria, and QA review before stage completion.	Review approved qualification reports and closure of deviations.
4	Weak user-access/password controls	Review user roles, privileges, password settings, and unauthorized access risks. Correct inappropriate access immediately.	Implement role-based access, periodic user-access review, password policy, and controlled account creation/deactivation.	Periodic access review confirms only authorized users retain appropriate privileges.
5	Audit trail/data integrity gaps	Enable and verify audit trail functionality and investigate any identified data-integrity deficiency.	Establish SOPs for audit-trail review, electronic records, data review, and ALCOA+ practices.	Periodic audit-trail review shows complete, attributable, and traceable records.
6	Inadequate backup and recovery	Verify current data backup, restore capability, storage location, and recovery process.	Establish scheduled backup, periodic restore testing, retention requirements, and backup monitoring.	Successful documented restore test demonstrates data recoverability.
