Understanding how to write a superb Computer Qualification Protocol starts with the unique three level User Requirements Specification (URS) document. Since most documents; post the URS, will either fully, or partially, base their contents on the URS, it is essential that this document clearly, concisely and in a manner that is testable, specifies the exact requirements of the end user. It is also essential that these exact testable requirements remain attributable through the development of the Design Specification (DS) to the actual lines or groups of lines of code that enable them.
The Validation Master Plan - VMP, must be specific about this and all cGMP
requirements, and instruct all personnel involved in the computer qualification program, of the importance of maintaining this traceability through the Installation Qualification - IQ - Operational Qualification - OQ - Performance Qualification - PQ.
Traceabilty of the URS functionality, to lines of code is an essential element in computer qualification. Once this traceability is established future maintenance and modification of software is made much simpler and more manageable.

Understanding the intricacies of conforming with the "How to write a superb computer qualification protocol" will be explained further as you read through this text. The guide-lines laid out in Good Automated Manufacturing Practices GAMP 5 , for the computer qualification template of automated systems including automatic computerized manufacturing equipment, control systems, automated laboratory systems, manufacturing execution systems and computers running laboratory or database systems. These computerized systems generally consist of the hardware, software and netware components, together with all control functions and GAMP 5 is a useful guide in scoping your validation online activities for such systems. It must be remembered at all times that GAMP is collective ideas from the computer qualification industry and does try to be all things to all people.
Which at times means certain sections can appear to contradict other sections. On a recent project when a group was set up to develop a Risk Assessment (RA) document from GAMP 5, after four weeks they were still divided and unable to reconcile their company's requirements with the alternative strategies given in GAMP. It bodes well to never forget that GAMP 5 is a guide from the end users point of view. The actual legal requirements come from the regulators, and obviously take precedence. Validation Online's computer qualification Template protocols start with the development of a detailed three layer URS and progress through the VMP - IQ - OQ - PQ. Each of these documents are interactive fully detailed and simple to use. Understanding how to write a superb Computer Qualification Protocol is not easily understood; However each of our protocols is preceded with an SOP which will guide authors through all phases of protocol generation completion.
The verification that the end users requirements, as detailed in the URS have been fully satisfied, is paramount to the equipment being correctly qualified. Often this is hard to verify since the traceability from URS functionality to the actual hardware or software utilized is lost in the various specification designations that range from the functional specification to the design specification to code requirements. However unless the effort is made to maintain this traceability , validation is flawed and future maintenance and or modifications can become extremely problematic. in these circumstances understanding how to write a superb computer qualification protocol- becomes essential.
The Validation Master Plan - VMP, must be specific about this traceability requirement and ensure that all personnel are aware of the importance of maintaining it.
Dynamic computer qualification template verifies the execution flow of software, including decision paths, inputs, and outputs. Dynamic testing involves creating test cases, test vectors and oracles, and executing the software against these tests. The results are then compared with expected or known correct behavior of the software. Because the number of execution paths and conditions increases exponentially with the number of lines of code, testing for all possible execution traces and conditions for the software is impossible. Static Analysis.
Code inspections and testing can reduce coding errors; however, experience has shown that the process needs to be complemented with other methods. One such method is static analysis. This somewhat new method largely automates the software verification process. The technique attempts to identify errors in the code, but does not necessarily prove their absence. Static analysis is used to identify potential and actual defects in source code. Abstract Interpretation Verification.
A code verification solution that includes abstract interpretation can be instrumental in assuring software safety and a good quality process. It is a sound verification process that enables the achievement of high integrity in embedded devices. Regulatory bodies such as the pharmaceutical regulators.
There is no regulatory requirement to re-validate a process as long as that process operates in a state of GMP control and no changes have been made to the process or output product, the process does not have to be revalidated. Whether the process is operating in a state of control is determined by analyzing day-to-day process control data and any finished device testing data for conformance with specifications and for variability. Revalidation on Relocation.
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 repeat of all computer qualification template activities, 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 revalidate the process. Revalidation Justification.
Part 820.75 of the QS regulation requires that validated processes be monitored and controlled so that when changes or process deviations occur, a manufacturer will know to review and evaluate the process and perform revalidation when appropriate. 21 CFR 820.75 (c) requires you to have documented procedures in place for evaluating; when revalidation is required. Procurement and Validation.
Recent research has highlighted that in the pharmaceutical and bio-medical industry, thirty two percent of all equipment procurement's are unsatisfactory. The major problem has been identified as companies not specifying in sufficient detail and or accuracy, what their actual needs are. The lack of a quality company approved User Requirements Specification (URS), leads to many companies having to resort to otherwise unnecessary and costly retrospective actions in understanding how to write a superb Computer Qualification Protocol for the equipment or producing unspecified documentation or engineering drawings, post procurement. These extraneous GMP requirements often cost more than the original equipment.
The Software User Requirements Specification (SURS) document should contain a written definition of the software functions. This must define the functionality that the end user requires from the system. These requirements must be set out in a manner that is none ambiguous, clear and easy to understand. Further to this the requirements must be grouped or worded in a manner that renders them testable and verifiable. It is not possible for computer qualification template to be properly executed without having predetermined and documented software strong requirements to validate against. Typical software requirements specify the following:
a) All Computer Qualifications system inputs;
b) All Computer Qualifications System outputs;
c) All functions that the software system will perform;
d) All computer qualification template performance requirements that the software will meet.
e) The definition of all external and user interfaces.
f) Understanding how to write a superb Computer Qualification Protocol.
g) What constitutes an error and how identified errors should be handled.
h) Required response times;
i) The intended operating environment for the software.
j) All ranges, limits, defaults, and specific values.
k) All safety specifications & features.
Automated processes: When computers or automated computerized data processing systems are used in any way which can affect the quality, efficacy or regulatory records of a regulated product or process, the manufacturer must carryout computer qualification template of the software and hardware that make up the system. Post computer qualification template; proposed software and or computer changes must be approved prior to installation, and the validation status re-established post installation. These activities must be adequately documented.
In the diagram below it can readily be seen that the URS , along with the computer qualification template requirements; as given in the VMP , come together to form a document package consisting of the DQ , IQ , OQ and PQ from which the vendor can develop a fully legal and compliant product. Computer qualification template activities are grouped in two colors (orange and blue). The blue color is the requirement for standard computer qualification.
