An audit trail must be maintained, and the place and time of origin should be noted.
Questions related to Attributable prompt us to trace the origins and ownership of data in pharmaceutical manufacturing. They compel us to ask: Who generated this data? What process or individual is responsible for its creation? By ensuring data is attributable, we establish accountability and transparency, essential elements for maintaining integrity throughout the manufacturing process.
2. Legible:
This attribute refers to the readability and understandability of data. Data must be recorded in a durable medium and should be easily accessible in a human-readable format.
Questions related to legibility include: Is the data recorded clearly and comprehensibly? Can it be easily understood by individuals without specialized training? Is the medium used for recording data durable and resistant to damage or degradation? How readily accessible is the data in a format that can be understood by humans?
By ensuring legibility, organizations can enhance transparency and facilitate effective communication and decision-making processes.
3. Contemporaneous:
Data recording should be synchronous with data collection. The timing of each activity should be recorded, and any change to the original recording must be fully tracked and time-stamped.
Questions related to contemporaneous recording include: Was the data recorded at the time of data collection or activity occurrence? Are timestamps included to indicate when each entry was made? How accurately are changes to the original recording tracked and documented?
By ensuring contemporaneous recording, organizations can maintain the integrity and reliability of data, providing a clear audit trail and facilitating accurate analysis and decision-making processes.
4. Original:
The original records must be preserved to maintain data integrity. If an electronic data collection module is being used, then it should accurately record the raw data and protect the original data from any modifications.
Questions related to ensuring the originality of data include: Are the original records preserved in their unaltered form? Does the electronic data collection module accurately capture and store raw data without alterations? How is the integrity of the original data protected from unauthorized modifications or deletions?
By prioritizing the preservation of original records, organizations can safeguard against data manipulation or corruption, ensuring the reliability and authenticity of their data for regulatory compliance and decision-making processes.
5. Accurate:
All the data collected should be thorough, reliable, and error-free and must be an actual representation of the facts. When recording data electronically, data quality must be maintained by ensuring that the system has built-in accuracy checks and validation controls.
Questions related to accuracy include: Is the data collected comprehensive and free from errors or inconsistencies? Does it accurately reflect the actual facts or measurements being recorded? Are there built-in accuracy checks and validation controls in place within the electronic data recording system?
By prioritizing accuracy, organizations can ensure the reliability and credibility of their data, enabling informed decision-making and regulatory compliance.

6. Complete:
Controls should be in place ensuring that the data contains all details. All repeats or reanalysis performed should be included, and nothing must be deleted or removed from the date of documenting. An audit trail must be maintained, thereby demonstrating that data is complete.
Questions related to maintaining complete data include: Are controls in place to ensure that all necessary details are included in the data documentation? Is there a process in place to document all repeats or reanalysis performed? How is the integrity of the data maintained to prevent deletion or removal of information? Is there an audit trail system in place to demonstrate the completeness of the data?
By addressing these questions, organizations can ensure that their data remains complete, reliable, and trustworthy, meeting regulatory requirements and maintaining data integrity.
7. Consistent:
Data must be able to prove the correct sequence of events. Data should be arranged chronologically and must be dated and time-stamped in the expected sequence.
Questions related to ensuring the correct sequence of events in data include:
- Are data entries arranged chronologically according to the sequence of events?
- Is each entry dated and time-stamped accurately to reflect when the event occurred?
- How is the expected sequence of events determined and documented?
- Are there controls in place to prevent data entries from being altered or manipulated to disrupt the sequence?
By organizing data in chronological order and accurately time-stamping each entry, organizations can ensure that the integrity of the data is upheld, enabling effective analysis, auditability, and compliance with regulatory requirements.
8. Enduring:
To ensure that the data is accessible long after it is recorded, the material used to record that data should be long-lasting and durable. This can be accomplished by recording data in laboratory notebooks or using validated electronic systems with redundancy and backups.
Questions related to ensuring data accessibility and durability include:
- Are laboratory notebooks or electronic systems used for recording data?
- How is the durability of the recording material ensured to withstand long-term storage?
