When you intend to prospectively validate a process; an experimental plan called the validation process protocol is executed (following completion of all equipment, utility and facility cGMP qualification) before the process is put into commercial use. Most validation efforts require some degree of prospective experimentation to generate validation support data. This particular type of process validation is normally carried out in connection with the introduction of a new drug or medical device and or their manufacturing processes. The formalized process validation program should never be under taken unless and until the following operations and procedures have been completed satisfactorily:
The retrospective validation option is chosen for established products whose manufacturing processes are considered stable and when on the basis of economic considerations alone and resource limitations, prospective validation programs cannot be justified.
Prior to undertaking retrospective validation, wherein the numerical in-process and/or end-product test data of historic production batches are subjected to statistical analysis, the equipment, facilities and subsystems used in connection with the manufacturing process must be qualified in conformance with CGMP requirements.
The concept is also recognized in the FDA’s Guidelines on General Principles of Process Validation Using either data-based computer systems [28,29] or manual methods, retrospective validation may be conducted in the following manner:

Equipment combined IQ/OQ/PQ Protocol. $159.00
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.
This Validation, Risk & Requirements Plan (VrrP) is one document designed specifically to replace three. The contents of the three original documents were completely revised and edited into a more compact and interactive format. This new format will make a very significant difference to the man hours required to produce and execute these documents. There will also be a very noticeable reduction in the time required for the reviewing and approving tasks. This new document titled the VrrP replaces the VP, VRA & URS and now compliments our equally new 4Q Protocol, which integrates the DQ/IQ/OQ/PQ into one document.
This is an essential step forward for companies seeking to reduce validation costs without infringing regulatory standards.
4Q Equipment Validation Protocol (4Q-Equip) has been designed specifically to replace four standard protocols. By taking the contents of the four protocol and carefully weaving them into one notably easy to use protocol, we have made a significant advance in the task of streamlining validation documentation by reducing protocol numbers by close to 75%. The new bang up to date 4Q protocol replaces the DQ, IQ, OQ & PQ and now compliments our equally new VrrP Protocol. By integrating the old style DQ/IQ/OQ/PQ into one 4Q document there will be enormous savings in man hours in the authoring, reviewing, updating and approving tasks.
For everyone's convenience, it is still written in word.
The Standard Operating Procedure attached to this generic design qualification protocol, will chapter by chapter, take you through the task of raising a fully detailed document. The main body is split into fourteen tables, each one probing the design requirements and standards for the individual requirement. Safety and security along with user operability are very detailed. The document will lead you through all these design aspects allowing you to delete some you feel are not important to your equipment. It is an easy document to use and will ensure that you’re DQ’s are relevant, up to date and easy to execute. Practically all the requirements are in table form. Allowing fast and clearly presented results to be obtained.
The Performance Qualification is the last of the qualifying tests that equipment and processes are subjected to, prior to the actual first product run. It maybe that there are some steps in the process that can only be verified by actually running them (quick freezing and sublimation, to mention only two) or it somtimes is the fact that the product is a very expensive product, and can not be wasted. So no one wants to run the process with product, until they are completely certain there will be minimal waste.
