<\/a><\/p>\n<\/p>\n
So, Quality Assurance and Quality Control are part of a firm’s overall Quality System. However, as the above diagram shows, Quality Control is not Quality Assurance. Instead, it can be considered part of a company’s Quality Assurance program.<\/p>\n
There is a primary way to understand the difference between the two:<\/p>\n
- \n
- Quality Assurance focuses on preventing defects from occurring<\/li>\n
- Quality Control focuses on searching for and finding product defects<\/li>\n<\/ul>\n
<\/p>\n
What is quality assurance?<\/span><\/h2>\n
Quality Assurance<\/span><\/a> is part of a firm\u2019s quality control system. It is essentially the management of processes and procedures within an organisation to ensure that the output in terms of experience and product achieves a set minimum target.<\/p>\n
So, the difference between Quality Assurance and Quality Control is:<\/p>\n
- \n
- Quality Assurance is focused on Processes.<\/li>\n
- Quality Control is focused on Products.<\/li>\n<\/ul>\n
So examples of processes within Quality Assurance include:<\/p>\n
- \n
- Processes Documentation<\/li>\n
- Monitoring and Appraising<\/li>\n
- Vendor Management<\/li>\n
- Staff Training<\/li>\n
- Procedure Alteration Control<\/li>\n
- Standardised Review Methodology<\/li>\n<\/ul>\n
Quality Assurance has two fundamental objectives:<\/p>\n
- \n
- Be making a product that is fit for purpose<\/strong> \u2013 The products produced are made to meet the expectations of what is required of them.<\/li>\n
- Be Right First Time<\/strong> \u2013 The output is made without mistakes or the need for fixes. This avoids waste and the use of resources to correct errors.<\/li>\n<\/ul>\n
<\/p>\n
What is Quality Control?<\/span><\/h2>\n
Quality Control is an element of a company\u2019s Quality Assurance program. Therefore, its focus is to check the products and output of the company for defects, functionality and conformity. Quality Control work involves inspecting, testing and analysing products. These include:<\/p>\n
- \n
- Product Inspection<\/li>\n
- Batch Sampling<\/li>\n
- Functionality Testing<\/li>\n
- Laboratory Analysis<\/li>\n
- Software Compliance<\/li>\n<\/ul>\n
So, many firms use their own resources or hire third-party firms to conduct Quality Control. Global firms such as Goodada Inspections<\/a><\/span> provide many of these services worldwide.<\/p>\n
Quality Control uses standardised processes such as Acceptable Quality Levels (AQL) to determine a sampling plan and defect acceptance levels. If you are interested in learning more about this, please visit Goodada\u2019s AQL page<\/a><\/span>.<\/p>\n
<\/p>\n
Quality Assurance vs Quality Control what is the difference?<\/span><\/h2>\n
Quality Assurance and Quality Control have a very close relationship with each other. I like to use a football analogy to describe this relationship. So, Quality Assurance is a football team, and Quality Control is a player within the football team.<\/p>\n
Quality Assurance, also known as QA, is part of managing the quality system within an organisation. Therefore, it covers all the activities, processes and procedures which take place to ensure that outputs meet the required expectations of a plan. Quality Assurance can cover products, services and software.<\/p>\n
Checking the actual output against pre-determined targets is Quality Control. It comprises inspections, analysis and tests. If the quality control check results indicate issues, then corrections and adjustments within the Quality Assurance processes will be required.<\/p>\n
Many folks use Inspection firms such as Goodada Inspections. Goodada provides Quality Control Inspections in over 76 countries<\/a><\/span>.<\/p>\n
<\/p>\n
Does QA, QC and Inspection Services mean the same thing?<\/span><\/h2>\n
Clients often ask me, “Does QA, QC and Inspection services mean the same thing”. Well, the answer is not they are different, but they are all part of a quality system.<\/p>\n
QA is short for Quality Assurance. It is a process that aims to prevent problems and defects from occurring in products. Therefore, QA focuses on processes, procedures and workflows which make a product.<\/p>\n
QC is short for Quality Control. It is a process of searching for defects and quality issues in a product. QC focuses on the product.<\/p>\n
Inspections are a term for the physical work of checking a product, process or entity. Its objective is to analyse and provide feedback. So, the user of the information can then determine an appropriate course of action. Here is a link to describe the different Types of Inspections<\/a><\/span>\u00a0you can order from a third-party Inspection company.<\/p>\n
