Operational Qualification is a set of test cases used to determine whether or not a system is functioning properly. It also checks whether the software is intended to match the objective by using the provided test data, treating the test data as input, and producing the expected output.
What is OQ? This ensures that the things we’ve put in the document, as well as the things we’ve implemented, are correctly implemented and functional.
For example, If we have a login application that we need to login to. In the login test scenario, both invalid and valid input can be used. Is it working fine with the valid input or not? Is it displaying a relevant message with incorrect input or not? These are the test we have to consider in the Operational Qualification.
So Operational Qualification ensures that the application performs what it says it will do, how it will do it, and how it will operate in the case of incorrect input.
There is an instruction, an intended outcome, and an actual result for each step. If any discrepancy occurs it is tracked and resolved before the verification is completed.
What is difference between OQ and PQ?
Operating Qualification is the process of ensuring that a system or group of subsystems will work as expected under a variety of predicted operational scenarios.
Performance Qualifications are a set of test cases designed to ensure that a system works as intended under realistic situations. The User Requirements Specification’s performance qualification tests the requirements specified in the User Requirements Specification. In other words, Performance Qualification is the process of ensuring that a system or combination of subsystems can perform as intended in real-world scenarios.
The last stage in equipment qualification is Performance Qualification (PQ). It is similar to OQ in that it checks the operational requirements of the equipment, but in case of PQ the device will have to be checked for the load or process medium.
Operational Qualification Template
For OQ, there is no fixed template. Different organizations have developed their own templates and use them in different ways. This is the most basic type of OQ template that can assist you in learning how to write an OQ.
