"Quality control (QC) is a process by which entities review the quality of all factors involved in production."
Ensure that products meet defined standards and specifications.
Quality Control Basics: An introduction to the concepts and principles of quality control, including the definition and importance of quality control, the history of quality control, and the benefits of implementing a quality control program.
Statistical Process Control (SPC): A comprehensive approach to quality control that uses statistical methods to monitor and analyze process data, identify process variations, and maintain consistent quality in manufacturing processes.
Six Sigma: A data-driven method for improving manufacturing processes by reducing variability and eliminating defects. It relies on statistical quality control tools to measure and analyze process performance and identify opportunities for improvement.
Failure Modes and Effects Analysis (FMEA): A systematic method for identifying and analyzing potential failures in manufacturing processes, and determining their impact on product quality and reliability.
Total Quality Management (TQM): An approach to quality control that emphasizes a culture of continuous improvement, customer focus, and employee engagement. TQM incorporates all aspects of the organization, from product design to customer service, and involves a continuous cycle of plan-do-check-act.
ISO 9000: A set of international standards that define the requirements for a quality management system. These standards provide a framework for improving product quality, enhancing customer satisfaction, and achieving organizational effectiveness.
Lean Manufacturing: An approach to quality control that emphasizes the elimination of waste, improved efficiency, and streamlined processes. Lean manufacturing incorporates principles such as Just-in-Time (JIT) production, continuous improvement, and value stream mapping.
Quality Cost Analysis: A method for analyzing the costs associated with quality, including prevention, appraisal, and failure costs. By understanding the costs of quality, organizations can identify areas for improvement and implement strategies to reduce costs and improve quality.
Root Cause Analysis (RCA): A problem-solving method for identifying the underlying causes of failures or defects in manufacturing processes. RCA involves a systematic approach to identifying and correcting the root cause of a problem, rather than simply addressing the symptoms.
Design of Experiments (DOE): A method for systematically testing the effects of process variables on product quality. DOE involves the creation of controlled experiments and the measurement of the effects of different process variables on product quality.
Poka-yoke: A method for mistake-proofing manufacturing processes by preventing human error. Poka-yoke methods can include visual cues, mechanical devices, and process controls, and are designed to reduce errors and improve product quality.
Quality Auditing: A systematic review of manufacturing processes and quality control systems by internal or external auditors. Quality audits can identify areas of non-compliance with quality standards and provide recommendations for improvements.
Supply Chain Management: The management of the flow of goods and services from raw materials to finished products. Effective supply chain management is essential for maintaining consistent quality in manufacturing processes, as it involves managing suppliers, logistics, and quality control throughout the supply chain.
Risk Management: The identification, assessment, and mitigation of risks associated with manufacturing processes. Effective risk management strategies can reduce the likelihood and impact of product failures, defects, and recalls.
Continuous Improvement: An ongoing process of refining and enhancing manufacturing processes and quality control systems. Continuous improvement involves identifying areas for improvement, implementing changes, measuring the results, and continuing to improve over time.
Statistical process control (SPC): This type of quality control involves monitoring and controlling a production process to ensure it operates within specified limits and that product variability is minimized.
Inspection: This involves examining a product or component to detect defects and ensure that it meets quality standards.
Product testing: This is a process to determine if a product is reliable and meets specifications, including performance, durability, safety, and environmental impact.
Sampling: Sampling involves selecting a portion of a product or material for testing or inspection to ensure it represents the entire population.
Process capability analysis: This is a statistical method used to evaluate a production process to determine if it is capable of producing products that meet specifications.
Quality auditing: This is the systematic examination of business processes to ensure that quality standards are being met.
Six Sigma: This is a data-driven approach to quality control that seeks to eliminate defects and improve processes.
Failure mode and effects analysis (FMEA): This is a method for identifying, analyzing, and evaluating potential or actual failures in a product or process to prevent or mitigate their impact.
Total quality management (TQM): This is a management approach that focuses on continuous improvement and customer satisfaction by involving all employees in the process of quality control.
Lean manufacturing: This approach aims to minimize waste and optimize efficiency by eliminating anything that does not add value to the product or process.
"ISO 9000 defines quality control as 'a part of quality management focused on fulfilling quality requirements'."
"The three aspects emphasized in quality control are: elements such as controls, job management, defined and well-managed processes, performance and integrity criteria, and identification of records; competence, such as knowledge, skills, experience, and qualifications; soft elements, such as personnel, integrity, confidence, organizational culture, motivation, team spirit, and quality relationships."
"Inspection is a major component of quality control, where physical product is examined visually (or the end results of a service are analyzed)."
"Product inspectors will be provided with lists and descriptions of unacceptable product defects such as cracks or surface blemishes, for example."
"Quality control (QC) is a process...focused on fulfilling quality requirements."
