PDA Technical Glossary

PDA Technical Reports are highly valued membership benefits because they offer expert guidance and opinions on important scientific and regulatory topics and are used as essential references by industry and regulatory authorities around the world. These reports include terms which explain the material and enhance the reader’s understanding.

The database presented here includes the glossary terms from all current technical reports. The database is searchable by keyword, topic, or by technical report. Each definition provided includes a link to the source technical report within the  PDA Technical Report Portal.

TR 58: Temp Controlled Distribution TR 54-5: Quality Risk Management for the Design, Qualification, and Operation of Manufacturing Systems
Quality Risk Management (QRM)
A systematic process for the assessment, control, communication, and review of risk to the quality of the drug product across the product lifecycle.(TR43)(TR54-2)(TR54-3)(TR57)(TR67)(TR68) Documentation to prove that an installation/ equipment/process is designed and/or tested according to predefined specifications. Documentation may include Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ) and Performance Qualification (PQ).(TR58) A systematic process for the assessment, control, communication, and review of risks to the quality of the drug (medicinal) product across the product lifecycle.(TR 54-5)(TR 76)(TR88)

Risk Analysis
The estimation of the risk associated with the identified hazards. (TR13) (TR30) (TR44) (TR54) (TR54-2) (TR58) (TR54-5)
Source:
Risk Evaluation
The comparison of the estimated risk to given risk criteria using a quantitative or qualitative scale to determine the significance of the risk (TR30) (TR54-2) (TR44) (TR58) (TR54-5)
Source:
Risk Identification
The systematic use of information to identify potential sources of harm (hazards) referring to the risk question or problem description.(TR44) (TR54-2) (TR58) (TR54-5)
Source:
Risk Reduction
The process of decreasing the level of risk. (TR44) Process for mitigation or avoidance of quality risk when it exceeds a specified (acceptable) level (e.g., reduce severity, probability of harm, and improves detectability of hazards and quality risks). (TR58) Actions taken to lessen the probability of occurrence of harm and the severity of that harm. (TR54-2) (TR54-5)
Source:
Risk Review
An ongoing monitoring of events, output and results of the risk management process that takes into account new knowledge and experience. [A] step in the risk management process for taking in account of new knowledge and experiences. (TR44) (TR58) Review or monitoring of output/results of the risk management process considering (if appropriate) new knowledge and experience about the risk. (TR54-2) (TR54-5)

Validation
A documented program that provides a high level of scientific assurance that a manufacturing process will reliably produce acceptable product. The proof of validation is obtained through rational experimental design and the evaluation of data, preferably beginning from the process development phase and continuing through the commercial production phase. (TR01) A documented program that provides a high degree of assurance that a specific process, method, or system will consistently produce a result meeting predetermined acceptance criteria. (TR26) (TR57) (TR70) (TR74) Documented testing, performed under highly controlled conditions, which demonstrates that a process consistently produces a result that meets predetermined acceptance a result that meets predetermined acceptance criteria. Used to test processes, methods, and systems for which conditions can be controlled in the real world (i.e., after completion of testing, when the process is in use). Transportation processes can be qualified but not validated; in the real world, it is not possible to exert control over all parameters that could affect the transportation process (e.g., weather, customs, traffic delays, mechanical failures, etc.). (TR58) A documented program that provides a high de­gree of assurance that a specific process, method, or system will consistently produce a result meeting predetermined acceptance criteria. (Note: Vali­dation is a lifecycle program which may include development and qualification activities for one or more elements/systems that form a process.) (TR54-5) A documented program that provides a high degree of assurance that a specific process, method, or system will consistently produce a result meeting pre-determined acceptance criteria (17). (TR60-3)
