Key Point of Computer system Validation




Computer System Validation:- Computer System Validation (CSV) is often referred to as software validation. Regulated companies perform validation projects to prove that their software or system is performing the way it is supposed to work, and not performing in ways that it isn’t intended to work.

Why Need to Computer System Validation :- There are several of examples as to why software validation is important. Look at our library of Warning Letters to see more than 200 reasons to validate your software or systems. Our Computer System Validation Boot Camp students read a case study about Therac-25, a radiation therapy machine from the 1980s. Due to programming issues, the machine could administer the wrong amount of radiation to patients (often as a huge overdose), which led to serious injuries and even death. Had there been software validation standards in place, these types of instances could have been identified and remediated prior to the treatment of patients.
Computer system validation is serious and the FDA and other regulatory agencies do not take this lightly.

Definition of US FDA Term :- “Confirmation by examination and provision of objective evidence that software specifications conform to user needs and intended uses, and that the particular requirements implemented through software can be consistently fulfilled” – General Principles of Software Validation: Final Guidance for Industry and FDA Staff

KEY Point As Per USFDA Term
“Confirmation by examination” – must have defined user needs and intended uses. The user can be a patient, someone in the hospital, a lab tech, a QA engineer, a manufacturing person. Examine the software to confirm that it functions as defined in the requirements and that it will be suitable for its intended use.

“provision of objective evidence” – there must be defined software requirements. Document all validation activities and test results.

“user needs and intended uses” – examine the software to ensure that it meets the user needs and defined requirements. This could include design reviews, code reviews, testing, etc. Define what the user needs to do with the software and how they will use the software.

“particular requirements implemented through software” – confirm that the requirements can be consistently fulfilled (not just in a single situation). This could include stress testing multiple data sets, performance testing with many users in many locations, testing with multiple browsers or web apps, testing from multiple devices (and even mobile apps), etc. Define how the software needs to work to enable the intended use.

“consistently fulfilled” – need to have objective evidence of this confirmation (for inspections). Document all validation activities and test results. The examination needs to confirm that the software will work in all anticipated situations.
