Quality assurance process control

So PAC has indeed evolved to PAT, which encompasses not only process measurement, real-time quality assurance and control but process understanding to enable product quality by process design. The tools available to us for quality by design as defined by the FDA include ... 

But that sense of control can be regained and the result made rational and predictable through a careful Quality Assurance process that checks the submission against FDA established criteria and through the use of an internal, self-regulating review process that applies the checklist criteria used by the FDA to the submission development process. 

Internal quality assurance and control procedures are designed to guarantee the reliability of the results generated by the laboratory QA and QC ensure that the reported results contain the appropriate accuracy and precision through stringent monitoring of the analytical process, documentation of procedures and method validation. 

The standard operating procedure (SOP) manual contains the procedures validated by the laboratory it is a complete set of instructions for pre-analytical, analytical and post-analytical methodology and also procedures for quality assurance/control, chain-of-custody and security. Each step in the handling of the specimen should be evaluated, optimized where possible and documented in the SOP. Important steps in the analytical process include collection, transport and accessioning of the specimen, sample preparation, isolation and detection of the analytes, production of the report and disposal of the specimen. This chapter focuses on the quality assurance and control issues for analytical method development and validation as well as statistical representation of the data. 

I C Energo s Quality Control was defined in the I C Energo document Quality Assurance Programme prepared as part of the subcontract work. This programme deals with the whole process from the general company quality system, subcontract review to quality assurance and control during the project realisation.

Establishing the requirements for a company s quality management systems, the ISO 9000 series provides a set of world-wide standards. Listing the features and characteristics required in the documented policies, manuals, and procedures of an organisation, its aim is to support a process of systematic quality assurance and control. However, rather than outlining the specific methods by which to achieve control, these standards represent a codification of the principles of control, enabling alternate interpretation and application across a wide range of environments. The series encompasses five individual standards ... 

Quality Control and Quality Assurance Process This PP element is likely to be needed if your organization does not provide a quality control/quality assurance (QC/QA) procedure. QC/QA is discussed in Chapter 7. 

Quality assurance and control are very important to the high-volume production process of lead-acid batteries. Quality assurance refers to the process of verifying or determining whether the lead-acid battery meets the product specifications. Quality... 

To achieve quality assurance and control, it is critical to ensure the following checks are implemented throughout the raw material and manufacture process ... 

Quality Assurance Configuration Control Reliability System Safety Maintainability Software Assurance and Parts, Materials and Processes requirements and application control. Figure 1 shows Levels I and II of the PSS-01 documentation tree, while Figure 2 shows Levels II and III of the Safety documentation tree. 

The quality assurance and control group also is responsible for ensuring that all products are manufactured and processed in accordance with the current Good Manufacturing Practices (GMP) issued by the FDA, and also with company policies. 

For instance, measures which require the redesign of production processes to minimise pollution will also provide the opportunity for new quality assurance and control systems to be put in place. 

To operate the MPI or LPI equipment at stable and reprodncable inspection conditions modern units are equipped with a monitoring and control system called "Quality Assurance Package" (termed QAP). The QAP System is ba.sed on an industrial PC with a bus system and field sensors. It ensures that process parameters important for the reproducability of the MPI or LPI are controlled an held between defined limits by a central computer system. It can be adapted to any old system, as well as integrated into new systems. 

Control charts were originally developed in the 1920s as a quality assurance tool for the control of manufactured products.Two types of control charts are commonly used in quality assurance a property control chart in which results for single measurements, or the means for several replicate measurements, are plotted sequentially and a precision control chart in which ranges or standard deviations are plotted sequentially. In either case, the control chart consists of a line representing the mean value for the measured property or the precision, and two or more boundary lines whose positions are determined by the precision of the measurement process. The position of the data points about the boundary lines determines whether the system is in statistical control. 

Opera.tlon, Because of the long residence time of the materials (8—10 h), the blast furnace process can exhibit considerable inertia, and control is usually appHed where the goal is maintaining smooth, stable input conditions. One of the most important aspects of blast furnace control is supply of consistent quaUty raw materials, which is why there is a strong emphasis on quaUty control at coke plants, peUeti2ing plants, and sinter plants (see Quality ASSURANCE/QUALITY control). 

Storage and receiving are activities that can greatly contribute to a safe and economic operation. It is here that quality control can be achieved at minimal cost. Label verification and other quality assurance measures can increase the confidence level that the correct chemicals have arrived, thereby potentially circumventing the use of wrong chemicals. Wrongly shipped chemicals can be returned to the manufacturer with minimal or no cost to the batch operation owner. As with all processes and activities it is of great importance to apply the principles of inherent safety, in particular the minimization and attenuation principles (CCPS G- 41). 

Quality assurance programs are designed to serve two functions (1) assessment of collected air quality data and (2) improvement of the data collection process. These two functions form a loop as air quality data are collected, procedures are implemented to determine whether the data are of acceptable precision and accuracy. If they are not, increased quality control procedures are implemented to improve the data collection process. 

Several methods have evolved to achieve, sustain, and improve quality, they are quality control, quality improvement, and quality assurance, which collectively are known as quality management. This trilogy is illustrated in Figure 2.1. Techniques such as quality planning, quality costs, Just-in-time , and statistical process control are all elements of... 

The standard also requires that the instructions be derived from appropriate sources, such as the quality plan, the control plan, and the product realization process, which means that all instructions should be traceable to one or more of these documents. They should form a set, so that there are no instructions used outside those that have been approved by the planning team. This is to ensure that no unauthorized practices are employed. Another important aspect to consider is the use of informal practices - practices known only to the particular operator. Process capability should be based on formal routines, otherwise repeatability cannot be assured when operators change. 

If the subcontractor supplies statistical data from the manufacturing process that indicates that quality is being controlled, then an analysis of this data based on assurances you have obtained through site evaluation can provide sufficient confidence in part quality to permit release into the organization.
