I agree with hm243 that a reevaluation has more benefits than pitfalls when observing the various location of equipment use. However when multiple locations are set and frequent then a complete evaluation may not be necessary. If the equipment is evaluated each time the location is placed with proper results and the same performance then an IQ/OQ/PQ may not be needed every time a change occurs. I do not know how practical this approach is but can be effective.
I think it can get tricky when talking about process revalidation and what is required to qualify the equipment to be used in the process. In my opinion, I don’t think you would need to revalidate the process in EVERY situation that you are relocating equipment. For example, if you are relocating a PC used in a predominately manual process, there would be no value added by revalidating the ENTIRE process. However, I do think that you should document the events of the translation and the required validation elements that must be re-executed. At my company, we would boil this information that into a Process Assessment Evaluation form and our Process Assessment packets include a relocation form that explicitly states what needs to be done to qualify the equipment if it is moved.
When equipment is moved to a new location, installation and operation should be re-qualified. By comparing data from the original installation and operation qualification (IQ and OQ) and the re-qualification, the manufacturer can determine whether there have been any changes in equipment performance as a result of the move. Changes in equipment performance should be evaluated to determine whether it is necessary to re-validate the process.
This example is out of the scope of what I encounter with my job responsibilities but I agree with how others have stated that if the equipment is going to be taken a part and moved to a new location and its a more complex situation, that it would require to be re-validated to see if there are any changes with equipment performance. For as @kak33 mentions just a PC or a simple task that would not directly affect performance wouldn't necessarily require to be revalidated but the importance that all of these changes to need to be documented properly. The documentation is what helped us solve this week's simulation.
