What Does 21 CFR Part 11 Compliant Software Need to Support?

21 CFR Part 11 applies to electronic records required by FDA predicate rules and to electronic signatures used in place of handwritten signatures.

Key control areas include:

  • Validated intended use
  • System access controls
  • Audit trails
  • Record protection and retrieval
  • Authority checks
  • Electronic signature controls
Software can support these requirements, but software alone does not make an operation Part 11 compliant.

When Does 21 CFR Part 11 Apply to a CMMS?

21 CFR Part 11 applies when a CMMS is used to create, modify, maintain, archive, retrieve, or transmit electronic records that are required by FDA predicate rules, or when electronic signatures are used in place of handwritten signatures.

For maintenance, calibration, and validation systems, this may include:

  • Calibration records
  • Preventive maintenance records
  • Equipment qualification documentation
  • Validation tracking activities
  • Change history documentation
  • Electronic approvals and signatures
The key question is not simply whether the software is a CMMS, but whether it is being used to manage electronic records or signatures that are subject to FDA requirements.

What Controls Must 21 CFR Part 11 Compliant Software Support?

Part 11 software should support the technical controls needed to maintain trustworthy electronic records and electronic signatures. The regulated organization remains responsible for defining intended use, validating the system, governing access, establishing procedures, training users, and managing record retention.

ControlWhat the software must supportEvidence to requestOperating responsibility
Validated intended useConsistent operation for defined regulated functionsSpecifications, test evidence, and validation support documentationDefine intended use and perform appropriate validation
Access controlUnique users, authentication, permissions, and restricted functionsSecurity model, role definitions, and authentication behaviorApprove users, assign roles, and periodically review access
Audit trailsSecure, computer-generated, time-stamped history of applicable record changesAudit-trail examples, configuration information, and test resultsDefine review expectations and investigate significant events
Record protection and retrievalAccurate records, retention, protection, readable retrieval, and copiesBackup, recovery, export, retention, and retrieval informationEstablish retention periods and backup/recovery procedures
Authority checksRestrict applicable actions to authorized individualsPermission matrix, workflow behavior, and authorization controlsDefine authority levels and maintain user governance
Electronic signaturesControlled signature execution and permanent linkage to the associated recordSignature workflow, authentication behavior, and signature examplesVerify identities, establish procedures, and manage credentials

What Are the Requirements for Audit Trails?

Where applicable, audit trails must be secure, computer-generated, time-stamped, attributable, retained for the required period, and available for review.

Regulatory requirement

Part 11 requires secure, computer-generated, time-stamped audit trails for applicable record creation and modification activities.

Implementation guidance

The operating company should define which audit-trail events require review, who performs the review, how often it occurs, and how unusual activity is investigated.

What Are the Requirements for Electronic Signatures?

  • Each electronic signature must be unique to one individual
  • The organization must verify the identity of each signer
  • Non-biometric signatures must use appropriate identification components
  • Controls must prevent unauthorized use of signature credentials
  • The signature must remain permanently linked to the associated electronic record
  • Signed records should show the signer, date and time, and meaning of the signature where applicable

How Must Electronic Records Be Protected and Retrieved?

Electronic records must remain accurate, complete, protected, and available throughout the required retention period.

  • Generate accurate and complete copies of records
  • Protect records from unauthorized alteration or deletion
  • Retain records for the required period
  • Maintain controlled system access
  • Support readable record retrieval
  • Make records available for inspection and review

Which Controls Must the Software Provide, and Which Responsibilities Remain With the Operating Company?

Software Should Provide

  • Access-control functionality
  • Audit-trail functionality
  • Electronic-signature functionality
  • Record protection and retrieval capability
  • Authority and permission controls
  • Available technical and validation evidence

Operating Company Responsibilities

  • Define intended use
  • Validate the system for that intended use
  • Establish procedures
  • Train users
  • Govern user access
  • Perform periodic reviews
  • Define record-retention requirements
GxP compliance software can provide the necessary technical controls and supporting evidence, but it cannot make an operation Part 11 compliant by itself.

What Evidence Should a Buyer Request From a Validated CMMS Vendor?

A buyer should request enough information to understand how the software works, evaluate whether it fits the intended use, and determine what validation work will still be required.

Intended-use fit
Functional specifications
Audit-trail behavior
Electronic-signature behavior
Security and permissions model
Release and change information
Validation support documentation
Test evidence
Backup and recovery information
Vendor support boundaries

Vendor documentation can reduce validation effort, but the regulated organization remains responsible for determining whether the software is suitable and validated for its actual intended use.

Common Misconceptions About 21 CFR Part 11 Software

The software is FDA certified

The FDA does not certify or approve software products. Vendors provide systems designed to support regulatory requirements, but validation and compliance remain the responsibility of the regulated company.

Any maintenance software will work

General maintenance tools may lack audit trails, access controls, or validation documentation needed in regulated environments.

More complexity equals better compliance

Highly configurable enterprise systems often increase validation scope and administrative burden without improving documentation integrity.

Software used to manage these records must support those expectations.

21 CFR Part 11 compliance software refers to systems designed to support FDA requirements for electronic records and electronic signatures in regulated environments.

For pharmaceutical, biotech, medical device, and nutraceutical companies, maintenance, calibration, and validation records are often considered GMP records. When stored electronically, these records must meet expectations for:

  • Audit trail traceability
  • Secure user authentication
  • Controlled system access
  • Record protection and retention
  • Inspection-ready retrieval
  • E-signed document preservation
Software used to manage these records must support those expectations.

Frequently Asked Questions

Does 21 CFR Part 11 require electronic signatures?

No. Part 11 does not independently require electronic signatures. When an applicable FDA regulation requires a signature and an organization uses an electronic signature, Part 11 establishes requirements for the associated electronic record and signature.

Does Part 11 apply to every electronic record?

No. Part 11 generally applies when records required by an FDA regulation are maintained electronically, or when electronic signatures are used in place of required handwritten signatures. Applicability depends on the record, its intended use, and the underlying regulatory requirement.

Does GxPReady make my company compliant?

No software product makes an organization compliant by itself. GxPReady includes technical controls designed to support Part 11 compliance, but compliance also depends on system configuration, validation, company procedures, user administration, training, and how the system is used. The GxPReady system development, turnover package and process are designed to minimize the time to compliance.

How does validation work with GxPReady?

GxPReady includes a structured validation package that supports customer validation activities. Because the application is standardized and requires minimal configuration, validation is less time and resource intensive than with heavily customized enterprise systems.

What Part 11 controls does GxPReady support?

GxPReady supports role-based access control, audit trails, electronic signatures, and electronic records designed to support 21 CFR Part 11 requirements. Appropriate procedures, user administration, training, and validation are also required and supported as part of the turnover process.

Does GxPReady include an audit trail?

Yes. GxPReady maintains audit-trail information for applicable regulated records to support traceability and review of record changes. Audit trails should be reviewed and managed according to company procedures and the risk associated with the records.

What must customers do before using GxPReady for regulated work?

Customers should define the system’s intended use, establish user roles and access, complete the required validation activities, train users, and implement appropriate procedures for system administration, electronic signatures, audit-trail review, record retention, and change control. This process is streamlined by our approach to the system design, development, documentation, and turnover process.
