This document discusses various aspects of quality control including: 1. It defines quality as the degree to which a product meets customer needs based on factors like design, production, and inspection. 2. It describes types of inspection as preventive (finding defects before production) and corrective (finding defects after production). 3. It defines quality control as processes used to ensure uniform, acceptable product quality and analytical quality control as procedures to ensure consistent, accurate lab test results. 4. It discusses statistical quality control using parameters and statistics to analyze process variations, good manufacturing practices to ensure quality products, and quality assurance to implement quality system activities so requirements are fulfilled.

- 3. What Is Quality ? The quality of a product is the “degree of perfection” i.e. the totality of features and characteristics of a product or service that bears on its ability to satisfy the needs of the customers. The quality of a product depends upon a number of factors such as design and specifications, production process, quality of raw materials used, quality of machines and equipments, man power expertise and skill and the inspection.
- 4. Types of Inspection: Depending upon the objective, inspection can be of two types, namely, preventive and corrective. The primary purpose of it is to discover the defective parts that have already been manufactured and prevent their use in the final product. The idea is to prevent the inferior parts from further processing down the production line in order to reduce the cost of production.
- 5. What is Quality Control? Quality control is defined as an industrial management technique by means of which products of uniform acceptable quality are manufactured. It is a Process or system for monitoring the quality of laboratory testing, and the accuracy and precision of results.
- 6. What is the goal of QC? To detect SIGNIFICANT errors rapidly Report out good results in a timely manner Be cost effective and simple to use If there is an error, identify the source of the error
- 7. What is an error??? A wrong answer. A significant error is one that changes the diagnosis Wrong answers can be caused by random errors or by systematic errors
- 8. Types of Errors Random Systematic Fluctuations Reagent problem Temperature Device problem Personnel
- 9. Types of Quality Control:- Internal Quality Control When a company institutes protocol to check their system, this is called internal quality control. External Quality Control When products or data is sent to an outside business not affiliated with the company, this is external control. One example of external control is in food production.
- 10. Analytical Quality Control Analytical quality control, commonly shortened to AQC refers to all those processes and procedures designed to ensure that the results of laboratory analysis are consistent, comparable,accurate and within specified limits of precision. In well managed laboratories, AQC processes are built into the routine operations of the laboratory often by the random introduction of known standards in to the sample stream or by the use of spiked samples.
- 11. Statistical Quality Control (SQC) A process by which a product/service is checked during its creation using certain set parameters and statistical techniques to measure and analyze the variation within the process. WHAT IS IT USED FOR: To monitor the consistency of product/service quality and maintain processes to a fixed target as designed. To drive improvement actions within an organization.
- 12. Advantages of Statistical Quality Control (SQC): The advantages of SQC are as follows:- (1) It ensures control, maintenance and improvement in the quality standards. (2) It provides better quality assurance at lower cost of inspection. (3) It reduces the wastages of time and materials to the minimum. (4) The very presence of SQC policy in an organization improves and makes them quality conscious. (5) It provides basis for resolving differences among the various interests in the organization.
- 13. What can be controlled using SQC? VARIABLES ATTRIBUTES Variable Measures are Attributes are those that can be measured characteristics that are on a continuous scale, for assessed by judgement example i.e. have two states such length, time, weight.... as right or wrong, looks OK or not OK.
- 14. Good Manufacturing Practice A good manufacturing practice (GMP) is a production and testing practice that helps to ensure a quality product. Basic concepts of all of these guidelines to safeguard the health of the patient as well as producing good quality medicine, medical devices or active pharmaceutical products.
- 15. Quality Assurance Quality assurance (QA) refers to the systematic activities implemented in a quality system so that quality requirements for a product or service will be fulfilled. QA includes management of the quality of raw materials, assemblies, products and components, services related to production, and management, production and inspection processes
- 16. Conclusion: When it comes to our focus, we understand that when quality control makes sure the end product meets the quality requirements, quality assurance makes sure that the process of manufacturing the product does adhere to standards. So Quality control can be noted as a reactive process.
