Records retention

Records retention is the controlled practice of keeping and disposing of records for defined periods based on legal, regulatory, customer, and operational requirements. In industrial and regulated manufacturing environments, it applies to both paper and electronic records, including production, quality, maintenance, engineering, IT/OT, and training documentation.

What records retention includes

In a manufacturing context, records retention commonly covers:

• Quality and compliance records such as inspection reports, nonconformance reports, CAPA files, batch records, electronic DHRs, FAI packages, audit reports, and calibration / MSA documentation.
• Production and traceability records including travelers/routers, as-built and genealogy data, material certificates, maintenance logs, and repair histories.
• Design and engineering records such as drawings, specifications, ECN/ECO history, and configuration baselines.
• Training and competency records including operator qualifications, training completion records, and authorization to perform specific processes.
• IT/OT system records like audit logs, access logs, backup archives, and system configuration history where required for traceability or cybersecurity evidence.

A records retention approach defines:

• Which records are considered official records.
• How long each record type is kept (retention period).
• How and where records are stored during that period (systems, locations, media).
• How records are protected from loss, alteration, or unauthorized access.
• How records are disposed at end of life (e.g., secure destruction or deletion) in a controlled and documented way.

Operational meaning in manufacturing

Practically, records retention in manufacturing is implemented through:

• Retention schedules or policies that group record types (for example, production records, supplier quality records, training records) and define retention periods, often aligned with standards, contracts, or customer expectations.
• System configuration in MES, ERP, QMS, PLM, and document control systems to store records for the required duration, maintain version history where applicable, and prevent premature deletion.
• Backup and archival practices that ensure retained records remain accessible and readable for the full retention period, taking into account media and format changes.
• Disposition workflows for reviewing and approving the destruction or deletion of records when their retention period expires, with evidence of the decision and actions taken.
• Audit trails to show what was retained, where it is stored, and when or how records have been modified or disposed.

Typical drivers of records retention periods

Retention periods are often influenced by:

• Regulations and standards in areas such as aerospace, medical device, pharmaceuticals, food, defense, and general quality management.
• Customer and contract requirements specifying how long build histories, inspection records, or repair records must be available.
• Internal risk and traceability needs, for example, keeping genealogy records for the expected service life of a product plus an additional buffer.
• Cybersecurity and data protection obligations, which can require both minimum and maximum retention for certain types of system and access logs.

Common confusion

• Records retention vs. document control: Document control focuses on ensuring that current, correct versions of procedures, work instructions, and specifications are available and governed. Records retention focuses on how long completed records (evidence of work performed or decisions made) are kept and how they are disposed, regardless of whether the underlying procedure has changed.
• Records retention vs. data backup: Backups protect against data loss and support recovery. Records retention is about the defined life cycle of records (creation, active use, archival, and disposal). Backups should support, not replace, formal retention policies.

Link to compliance and audits

In regulated manufacturing, records retention is a common focus in audits and assessments. Organizations are often asked to show:

• Documented retention schedules for key record types.
• Evidence that required records can be retrieved for the full retention period.
• Evidence that records past their retention period are handled according to the policy, including secure and controlled destruction where appropriate.
