Quality Engineering : From Everything About It to the Kind of Job Roles in the Field.



Are you hearing the term "Quality Engineering" for the first time? Does it sound like a cool, but vague term that could mean just about anything? Well, let's dissect the term. Quality is the first word. In the field of Quality Management, Quality specifically refers to "Fitness for Use", and the quality of a product or service can be inferior or superior compared to another. Or it could comply or fail to comply with a standard.

Onto the next word in the term, Oxford Languages defines engineering as "the action of working artfully to bring something about". That "something", if it works, is incorporated into a process or service. Quality Engineering is thus a field of work where solutions are created in a manner that meets the necessary standards. 

Today everyone wants to gain customers. The competition is high and everything needs to be quick and efficient. Among all this to gain and retain customers, we need to ensure good quality of the service is provided and the products we make!! For emerging technologies, the old system of quality control and testing is not enough. Hence businesses have started using Quality Engineering Services!! This is something new and is required in today’s emerging technological landscape. 

What is Quality Engineering?

Quality engineering is a discipline of engineering. It is concerned with the practice and principles of product and service quality assurance and control. If you look at software development. It is the management, development, maintenance, and operation of IT systems. This includes enterprise architectures with a high-quality standard.

Now, introducing you to the testing methodology, named “Quality engineering”. This can reduce costs and improve productivity in parallel. What is quality engineering (QE)? How does it differ from traditional quality control? Let’s find out.

You need to ensure services or products are designed, developed, and manufactured to meet or exceed the customer’s expectations. Quality Engineering includes development systems and analysis methods for this. Quality Engineering encloses all tasks from ideation to execution. These would include the analysis of a product’s design, its development, and finally the manufacturing processes. The focus is on improving the quality of the final product and an efficient production process. It includes identifying and reducing waste in different forms. Quality Engineering tools and methods are often developed and implemented using a cross-functional approach. It involves many business and engineering disciplines. Quality Engineering has a broad range of tools and methodologies. A few of these are given below. However, this is a limited list and we can include more:

  • Implementation of Quality Management System (QMS)
  • Use of Advanced Product Quality Planning (APQP) tools from the design concept, checking to manufacture, and finally monitoring of the finished product. Tools like Failure Mode and Effects Analysis (FMEA) and Quality Function Deployment (QFD) are useful here
  • Integrate Voice of the customer (VOC) into new product designs and processes. House of quality can be used here
  • Identify and eliminate waste in business and manufacturing processes
  • Collaborate with internal and external suppliers to ensure materials, assemblies and components meet the quality and design requirements
  • Implementation of process controls such as Statistical Process Control (SPC)
  • Fix root causes: Work with customers to resolve any quality issues through the application of Problem-Solving tools such as 8D, 5 Why, Cause and Effect / Ishikawa diagrams etc.  Implementing effective Root Cause Analysis (RCA) measures to prevent the issue from re-occurring
  • Ensure process controls are effective by developing of appropriate testing methods and inspections

Quality Engineering in Software

How do you measure the quality of IT services? It could be customer satisfaction, the average time to resolution, and system downtime. There are other criteria too.  These consist of subjective and objective opinions. The focus is on functions, reliability, usability, and security. To cater to these criteria, QE integrates methods and tools taken from various disciplines, like enterprise architecture and product management, information security management, software and systems engineering, etc.

Here is a list of the most popular philosophies and tools encompassed by QE:

  • Quality Management System (QMS)
  • Total Quality Management (TQM)
  • Kaizen
  • Six Sigma
  • EFQM Excellence Model (Concept for business excellence developed by the European Foundation for Quality Management)

Quality Engineers

Quality Engineers are the torchbearers here. They develop & maintain the various quality disciplines in the world of Quality Engineering. They are professionals who have a deep understanding of quality principles. They understand process evaluation and control too. A quality Engineer is sometimes called a Quality Assurance Engineer. They are responsible for developing, implementing, and maintaining quality systems. These systems measure, monitor, and control product quality. This includes process quality in the production process too. They are responsible for embedding quality standards in products and associated production processes. To achieve this, they work across various departments of the organization.

Quality Engineers

They interact from design teams to manufacturing teams and beyond. Quality Engineers must know the use of SPC in monitoring the manufacturing processes. They should understand process capability too. They often determine the parameters and develop appropriate end of line testing. They set the acceptable limits for the results here. Quality Engineers must be well acquainted with the use and application of problem-solving tools. They should be experts in process improvement and troubleshooting. A Quality Engineer must be able to understand and discover the process issues. This will enable them to develop effective countermeasures including process or product changes. These are necessary to ensure that quality standards are upheld. The results are that the customer’s requirements and expectations are met or exceeded.
