Jmp statistical software1/4/2024 This was a repeat violation from a previous FDA-483 that was issued to your firm. Below is a section from a warning letter that refers to the failed validation of an off-the-shelf helpdesk software product, and a document management tool.įailure to validate computer software for its intended use according to an established protocol when computers or automated data processing systems are used as part of production or the quality system as required by 21 CFR § 820.70(i). Many warning letters received by manufacturers cite a violation of this regulation. For example, go to Stat > Quality Tools > Capability Analysis > Nonnormal and enter the column to be evaluated and select the appropriate distribution. For example, validate capability analysis for Non-Normal Data. You can use a Traceability Matrix to track your requirements and test cases. An auditor may find that a system “has not been validated” if a requirement is discovered without a test case. Each requirement must trace to a test case. The validation for intended use consists of mapping the software requirements to test cases. To validate Minitab, you will need to document the “intended use.” Software packages that are used to monitor the process and determine the quality level, such as Minitab, should be validated. If the Capability Analysis > Nonnormal is chosen and an appropriate distribution is selected (Weibull in this case), the Ppk (0.69) and defect rate (8993 defects per million) are found to be poor, as shown in the following graph: If this was the only capability analysis available in Minitab, then the software would not be validated for non-normal capability analysis.įortunately, Minitab does have non-normal capability analysis. Minitab has not calculated anything incorrectly, but since this data is non-normal, the wrong procedure was applied. However, this manufacturer would be misled into believing this is a good process based on these numbers. In the first graph below, you can see the Ppk (1.26) and defect rate (82 defects per million) are quite good by most standards. Let’s say they use Minitab’s Capability Analysis > Normal to perform the capability analysis. If the amount of an impurity exceeds 450 mg/mL, the product is considered defective. Here is an example:Ĭompany XYZ is using Minitab to estimate the probability of a defect in a manufacturing process. There is good reason for the “intended use” guidance. If the vendor can provide information about their system requirements, software requirements, validation process, and the results of their validation, the medical device manufacturer can use that information as a beginning point for their required validation documentation.” Intended Use For OTS software and equipment, the device manufacturer may or may not have access to the vendor's software validation documentation. “The device manufacturer is responsible for ensuring that the product development methodologies used by the off-the-shelf (OTS) software developer are appropriate and sufficient for the device manufacturer's intended use of that OTS software. The FDA provides additional supportive information for medical device companies via Section 6 of “Validation of Automated Process Equipment and Quality System Software” in the Principles of Software Validation Final Guidance for Industry and FDA Staff, January 11, 2002. These validation activities and results shall be documented.” All software changes shall be validated before approval and issuance. “When computers or automated data processing systems are used as part of production or the quality system, the manufacturer shall validate computer software for its intended use according to an established protocol. This is described in FDA’s Code of Federal Regulations Title 21 Part 820.70(i): It is up to the software purchaser to validate software used in production or as part of a quality system for the “intended use” of the software. Software vendors who claim their products are FDA-validated should be scrutinized. It is a common misconception that software vendors can go through a certification process to achieve FDA software validation. Minitab does extensive testing to validate our software internally, but Minitab’s statistical software is not-and cannot be-FDA-validated out-of-the-box. Food and Drug Administration (FDA) for use in the pharmaceutical and medical device industries. We're frequently asked whether Minitab has been validated by the U.S.
