Quality Control (QC) is a reactive process focused on identifying and fixing defects in the finished product through testing and inspection. In simple terms, QA focuses on preventing problems, while QC focuses on finding problems. The interplay between Quality Assurance vs Quality Control is crucial for delivering high-quality products.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s important to understand the meaning of each quality management aspects;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Quality Assurance (QA)<\/strong>:<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Quality Assurance otherwise known as&nbsp;<em>QA Testing<\/em>&nbsp;is defined as a process of assuring that quality requirements will be fulfilled. This is carried out to ensure companies provide high-quality products for their esteemed customers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You will learn more about QA if you enroll in&nbsp;<strong><a href=\"https:\/\/www.h2kinfosys.com\/courses\/qa-online-training-course-details\">quality assurance testing training<\/a><\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Quality Control (QC)<\/strong>:<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Quality Control otherwise known as&nbsp;<em>QC Testing<\/em>&nbsp;is defined as systematic test procedures used to verify the safety and effectiveness of a product. The main aim of Quality Control is to ensure that products meet the expected requirements by reviewing and testing their functionality.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Find&nbsp;<strong><a href=\"https:\/\/www.h2kinfosys.com\/courses\/qa-online-training-course-details\">software quality assurance course<\/a><\/strong>&nbsp;tutorials online to learn more about QC.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this guide, we will have an in-depth look at the major differences between Quality Assurance and Quality Control. These differences include their meaning, their aim, their focus, and how each process is carried out. Furthermore, we will have a look at their respective procedure differences, the tools used, and the statistical technique applied for each practice.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Major Differences Between Quality Assurance and Quality Control<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">I have decided to tabulate the differences Quality Assurance vs Quality Control for easy read and better understanding.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><\/td><td><strong>QUALITY ASSURANCE (QA)<\/strong><\/td><td><strong>&nbsp; &nbsp; &nbsp; QUALITY CONTROL (QC)<\/strong><\/td><\/tr><tr><td>1.<\/td><td>QA is a process that offers a level of assurance that the quality of product requested will be achieved<\/td><td>QC is a procedure that ensures that the quality of the product requested is fulfilled<\/td><\/tr><tr><td>2.<\/td><td>QA aims to prevent any form of defects in a product<\/td><td>QC aims to identify products defects and fix it<\/td><\/tr><tr><td>3.<\/td><td>QA is a preventive technique<\/td><td>QC is a corrective technique<\/td><\/tr><tr><td>4.<\/td><td>QA is process-oriented in such a way that it focuses on preventing quality issues in products<\/td><td>QC is product-oriented in such a way that it focuses on identifying quality issues in products<\/td><\/tr><tr><td>5.<\/td><td>QA is an action carried out to ensure quality during the manufacture of products.<\/td><td>QC is an action carried out to inspect the products after they have been manufactured.<\/td><\/tr><tr><td>6.<\/td><td>QA is a method used to manage product quality verification<\/td><td>QC is a method used to verify product quality validation<\/td><\/tr><tr><td>7.<\/td><td>QA is a form of proactive measure<\/td><td>QC is a form of a reactive measure<\/td><\/tr><tr><td>8.<\/td><td>The goal of QA is to improve the manufacture and testing process to prevent issues arising during the development stage of products<\/td><td>The goal of QC is to identify issues that may arise after a product is developed and also solve the issue before the product is launched&nbsp;<\/td><\/tr><tr><td>9.<\/td><td>QA execution is less time consuming<\/td><td>QA execution is more time consuming<\/td><\/tr><tr><td>10.<\/td><td>QA is all about verification activities<\/td><td>QC is all about validation activities<\/td><\/tr><tr><td>11.<\/td><td>Statistical tools and techniques are applied in the QA process which is known as Statistical Process Control&nbsp;<\/td><td>Statistical tools and techniques are applied in QC products output which is known as Statistical Quality Control<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, it is important to understand that every member of the production team involved in developing products is responsible for quality assurance while the responsibility of quality control lies on the shoulder of the particular team that tests products for defects. These are the major differences between QA and QC.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Processes and Procedures Involved in QA and QC<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here is a breakdown of the processes and procedures applied in QA and QC;<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Quality Assurance Process<\/strong><\/td><td><strong>Quality Control Procedure<\/strong><\/td><\/tr><tr><td>AuditingDocumentationChange ControlPersonnel TrainingSupply ManagementInvestigation Procedure<\/td><td>Product SamplingBatch InspectionLaboratory TestingValidation Testing<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Quality assurance is applied in the software development life cycle while Quality Control is applied in the software testing life cycle.
