Maintenance of the validated state is no less important than the validation itself.
Upon completion of proper validation and the launch of production, the object of validation / qualification moves into the state of operation and maintenance.
This means that from that moment one should take care that none of the activities performed should cause the loss of the validated state.
Properly implemented “Maintenance of the validated state” allows to save time and costs, when managing existing and validated system and/or equipment.
Stability after validation
Validate is not enough the key is to maintain the state of validation
The most common causes of the loss of the validated state are:
breakdowns and repairs
change implementation
amendments to laws and standards
What is also connected with the operation and maintenance state is also withdrawal from use.
The stage of withdrawal from use is also incorporated into the validation life cycle and requires taking appropriate action.
The most frequent processes being part of the maintenance of the validated state include:
We perform the following, among other things, as part of the maintenance of the validated state:
Procedures and instructions
We develop relevant procedures and instructions
Training
We conduct training and implementations as per the instructions mentioned above
Incident management and change control
We take an active part in incident management and change control processes (we review and assess changes, supervise scheduled actions, perform validation activities – for example, preparation of documentation and testing)
Reviews
We perform periodic inspections
Revalidation and requalification
We do revalidation and re-qualification (to the extent identified in the risk assessment)
