Validation protocol standards can only be guaranteed when all documents are authored using simplified English. The need for this is becoming more apparent everyday, as more and more regulated processes; documented in English, are executed by operators located in areas; around the world, where English is not their first language. When simplified English is used it is much easier for operators and translators to ensure the original authors written instructions are replicated accurately.
Validation Protocol standards must be used for writing the Functional Test (FT) if it is to be a stand alone document that can be executed and reviewed as part of the operational qualification. The FT should first be written at the FAT stage. This means that your vendor should write it, and so the vendor does in a high percentage of instances. It is criminal that having spent hundreds of hours authoring, developing and finally executing a detailed FAT at the factory, the document is allowed to die and never be used again. For instance in a project Validation Online was closely involved in, 87 people spent nearly one year in raising, approving and executing the FAT for a Distributive Control System, while on site, 30 people spent over a year writing the OQ qualification test scripts. The FAT reviewed and condensed would have done a much better job, partly because it was written by staff, who had direct access to the design staff who designed the DCS, but mainly because it was ready, and should have been freely available from the vendor.
The FAT and the FT, are the same as the re-qualifying tests that are carried out on laboratory and process equipment. It becomes a little obvious that if these document's were written to normal validation protocol standards, then, the one document could be used for the testing section in documents like, the FAT, FT, qualification and re-qualification of equipment.
The following method of construction must be used. The over-all protocol standards are shown in the SOP’s for the different protocols, here we are concerned about the testing element alone. All testing must be detailed and pre-approved by a qualified person to ensure the system under test has been adequately tested. Each test must comprise of;
Main Sub-headings in Test Script.
General details that must be adhered to.
This combination protocol has been produced in response to several hundred reader suggestions we received in our ‘Suggestions Section’. It has been carefully designed to make it the preferred choice for Process and Laboratory stand alone equipment. It is interactive, easy to use and suitable for all mixes of equipment with and without software.
The IQ section establishes documented verification that key aspects of the equipment adhere to approved design intentions and that the recommendations of the manufacturer have been suitably considered. The OQ section establishes that there is documented verification that the installed system functions as specified and that there is sufficient documentary evidence to demonstrate this. The PQ section gives documented verification that the equipment performance in its normal operating environment is consistently exactly as specified in the URS.
The Risk and Part 11 Validation Risk Assessment (VRA) protocol is becoming the most important document in the validation train. The VRA reassures the regulators that you have looked at specific equipment functionality and considered the appropriate level of validation that is required. You have also considered various aspects of its use and the implications of any malfunctions. From the results of this exercise the scope of all validation activity can and must be justified. This is a robust and simple to execute document, one that will lead you through the process and deliver a result that can be used as the foundation for your validation activities.
This VRA now includes the assessment table for categorizing and documenting the new 21 CFR Part 11 guidance ruling on what predicate data must be stored in a Part compliant system, along with the new broadsheet to establish your new database of part 11 records. (now mandatory).
