definition of robustness in method validation

A more general example of this parameter would be to imagine a footballer practising spot kicks using certain technique under given conditions. Please share. Robustness Validation is a modern qualification approach for Electronic Devices, Modules and Systems. Establishing documented evidence which provides a high degree of assurance that a specific process (analytical test method) will consistently produce a product (assay result) meeting its predetermined specifications and quality attributes (accuracy, precision, etc.) ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. © EMEA 2006 7 Validation of Analytical Procedures: Methodology The robustness of an analytical procedure is a measure of its capacity to remain unaffected by small, but deliberate variations in method parameters and provides an indication of its reliability during normal usage. There are many factors, including basic parameters (e.g. Figure: (left) Footballer practices spot kicks under given conditions. Inter-laboratory comparison as a means for method validation 7. robustness. RV represents an approach to qual- ification and validation that is based on knowledge of failure mechanisms and relates to specific Mission Profiles. during method qualification. Robustness is the evaluation of an analytical method wherein the results obtained are found to be reliable even when performed in a slightly varied condition. Full Assay Validation will include inter-assay and inter-laboratory assessment of assay repeatability and robustness. Robustness is a measure of a method’s capacity to remain unaffected by small but deliberate variations in procedural parameters. The ROBUSTNESS describes whether a titration method is sensitive to "hardware effects", such as different instruments (electrodes, titrators etc. The two-level full factorial design is the most efficient chemometric tool for robustness evaluation; however, it is inappropriate when the number of factors is high. It is calculated as a Relative Standard Deviation. Robustness and Ruggedness Definitions Robustness • “a measure of [an analytical procedure’s] capacity to remain unaffected by small, but deliberate variations in method parameters”* • prerequisite for a rugged method • separation robustness: sensitivity of resolution to small, intentional changes in separation variables that may occur Robustness testing deals with the critical operational parameters and the tolerances for their control. In computer science, robustness is the ability of a computer system to cope with errors during execution and cope with erroneous input. solution stability), internal parameters (e.g. ICH Q2(R1) Situating robustness in method development and validation. Now the same footballer is asked to take the kicks using a different sized ball, smaller target, higher atmospheric temperature or different boots. 1.2. Per ICH and USP definition3,4, the robustness/ruggedness of an analytical procedure is a measure of its capacity to remain unaffected by small but deliberate variations in parameters listed in the procedure documentation and to provide an indication of its suitability during normal usage.

As the ICH Q2(R1) doesn’t discriminate in such a way and gives a proper explanation about what is “intermediate precision” and “reproducibility” all other variable factors influencing method performance might be considered as robustness parameters. Specific details regarding method validation may be found in USP General Chapter <1225> entitled “Validation of Compendial Procedures”. (right) The same footballer tries to repeat the kicks under slightly varied conditions; a bigger sized ball, a sunnier day and higher temperature. Others propose to use the term ruggedness when analyzing external factors (like different analyst and instruments, which points to the same direction as intermediate precision) and robustness for internal factors characterizing method stability (like e.g. In conclusion, robustness is a strong parameter used during the development and validation of analytical methods that proves the functionality of the method under slightly different conditions. The authors identified all possible factors that in principle could affect the method and ran robustness studies on them (shown below): In this case the method was found to be very robust and was successfully transferred to different operational laboratories in Europe, USA, Japan, and China. However, robustness can also be described as the feasibility to reproduce the analytical method in different laboratories (then it is part of the parameter reproducibility) or under different circumstances without the occurrence of unexpected differences in the obtained results or performance parameters. 2001 Elsevier Science B.V. all rights reserved different instruments ( electrodes, titrators....
