Quality Assurance

What is QE?

Quality Engineering consists of analysis methods and the development of systems to ensure products or services are designed, developed and manufactured to meet or exceed the customer’s requirements and expectations.
Quality Engineering encompasses all activities related to the analysis of a product’s design, development and manufacturing processes for the purpose of improving the quality of the product and the production process while identifying and reducing waste in its many forms.
Quality Engineering methods and tools are often developed and implemented using a cross-functional approach involving multiple business and engineering disciplines.

Quality Engineering encompasses a broad range of methodologies and tools including but not limited to the following list:

• Creation, implementation and management of the Quality Management System (QMS)
• Application of Advanced Product Quality Planning (APQP) tools, such as Quality Function Deployment (QFD) and Failure Mode and Effects Analysis (FMEA), from the initial design concept to the manufacturing and monitoring of the finished product
• Integration of the VOC into new product designs and processes
• Working with internal and external suppliers to ensure materials, components and assemblies meet the design and quality requirements
• Identification and elimination of waste in manufacturing and business processes
• Implementation and monitoring of process controls such as Statistical Process Control (SPC)
• Development of appropriate tests and inspections to ensure that process controls are effective
• Working with customers to resolve any quality issues through application of Root Cause Analysis (RCA) and Problem-Solving tools such as 5 Why, 8D, Cause and Effect / Ishikawa diagrams etc., and implementing effective countermeasures to prevent the issue from re-occurring
  
  Quality Engineers are the front-line forces for developing, implementing and maintaining the various quality disciplines within the world of Quality Engineering.
  They are professionals who have gained a thorough understanding of quality principles and product and process evaluation and control.
  Quality Engineers are normally responsible for developing, implementing and maintaining the systems used to measure, monitor and control product and process quality in the production process. They work with design teams and manufacturing teams to institute quality standards for products and their associated production processes. Quality Engineers must understand process capability and the use of SPC in monitoring the manufacturing processes.
  In addition, they often define the parameters and develop appropriate end of line testing including setting acceptable limits for the results. Furthermore, the Quality Engineer must be well versed in the use and application of problem-solving tools, troubleshooting, and process improvement.
  A Quality Engineer must be able to discover and understand the process issues and develop effective countermeasures including process or product changes when necessary, to ensure that quality standards are upheld and the customer’s requirements and expectations are met or exceeded.
  
  The benefits of Quality Engineering are vast and can have a profound effect on product quality, process efficiency, and overall customer satisfaction.

What is Software Testing?

Software Testing is a process of verifying a computer system/program to decide whether it meets the specified requirements and produces the desired results. As a result, you identify bugs in software product/project. Software Testing is indispensable to provide a quality product without any bug or issue.

What is Quality Assurance?

Quality assurance can be defined as "part of quality management focused on providing confidence that quality requirements will be fulfilled." The confidence provided by quality assurance is twofold—internally to management and externally to customers, government agencies, regulators, certifiers, and third parties. An alternate definition is "all the planned and systematic activities implemented within the quality system that can be demonstrated to provide confidence that a product or service will fulfill requirements for quality."

Quality Assurance Stages:

1. Check product requirements
2. Risk assessment
3. Planning product quality improvement ideas
4. Test scheduling
5. Analysis of test results
   

Quality Assurance VS Quality Control

Quality assurance and quality control are two aspects of quality management. While some quality assurance and quality control activities are interrelated, the two are defined differently.

Typically, QA activities and responsibilities cover virtually all of the quality system in one fashion or another, while QC is a subset of the QA activities. Also, elements in the quality system might not be specifically covered by QA/QC activities and responsibilities but may involve QA and QC.
