A validation should check with objective means whether users can achieve the previously defined usage goals in a certain usage context. To put it in a nutshell: It is examined whether a product really does what the customer expects - does the product correspond to the intended purpose? In contrast to verification, the fulfillment of the requirements for the product is not checked, but how the product "works".
Objective means are used to check whether (for example, from a technical point of view) the conditions are in place that the objective can be achieved.
This is the formal and documented proof that an analysis method is suitable for the specific purpose and fulfills the requirements. An important part of accreditations and approval procedures in the area of drug approvals. Indispensable for procedures involving the higher federal authorities - e.g. BfArM (Federal Institute for Drugs and Medical Devices) and / or the American FDA.
Process validation is called process validation. ISO 13485 uses ISO 9000: 2015. The term process is broadly interpreted as "... a set of interrelated or mutually influencing activities, the input of which is used to achieve an intended result.".
Examples are: development, sterilization, production, hiring or sales process. Process validation is evidence that a process delivers the intended process results. ISO 13485 requires process validation if:
Usability validation could be translated as "usability test".
It should be determined whether the product is applicable and leads to the desired goal in the application. For this purpose, the applicability is checked with test persons within (e.g. a field trial) under defined special usage requirements.
An international standard IEC 62366 characterizes the conditions for a "usability validation". For projects with FDA approval, a look at the "Human Factors Engineering Guidance Document" from the FDA is recommended. It must therefore be specified:
The usability process draws the manufacturer's attention (e.g. by simulating worst case scenarios) to risks that may arise during the intended application. These are then to be assessed in risk management.
