Quality assurance & the way of applying it
Quality Assurance (QA):
is defined as an activity to ensure that an organization is providing the best possible product or service to customers. QA focuses on improving the processes to deliver Quality Products to the customer. An organization has to ensure that processes are efficient and effective as per the quality standards defined for software products. Quality Assurance is popularly known as QA Testing.
Quality assurance activities monitor and verify that the processes used to manage and create the deliverables have been followed and are operative.
Quality Assurance is a proactive process and is Prevention in nature. It recognizes flaws in the process. Quality Assurance has to complete before Quality Control.
History of quality assurance:
During the time of the First World War, manufacturing processes typically became more complex, with larger numbers of workers being supervised. This period saw the widespread introduction of mass production and piece work, which created problems as workmen could now earn more money by the production of extra products, which in turn occasionally led to poor quality workmanship being passed on to the assembly lines. Pioneers such as Frederick Winslow Taylor and Henry Ford subsequent varying quality of output. Taylor, utilizing the concept of scientific management,Ford emphasized standardization of design and component standards to ensure a standard product was produced, while quality was the responsibility of machine inspectors, “placed in each department to cover all operations at frequent intervals, so that no faulty operation shall proceed for any great length of time.
After World War II, many countries’ manufacturing capabilities that had been destroyed during the war were rebuilt. General Douglas MacArthur oversaw the rebuilding of Japan. He involved two key people in the development of modern quality concepts: W. Edwards Deming and Joseph Juran. They and others promoted the collaborative concepts of quality to Japanese business and technical groups, and these groups used these concepts in the redevelopment of the Japanese economy.
The way of applying Quality Assurance:
Quality assurance has a defined cycle , The phases of this cycle are:
- Determining the cause of the problem.
- Analyzing the amount of effort and engagement needed to fix the problem.
- Defining the most effective way of fixing it.
- Considering possible backfires upon making changes.
Quality assurance methods: Quality assurance utilizes one of three methods:
- Failure testing: which continually tests a product to determine if it breaks or fails. For physical products that need to withstand stress, this could involve testing the product under heat, pressure or vibration.
- Statistical process control (SPC): a methodology based on objective data and analysis and developed by Walter Shewhart . This methodology uses statistical methods to manage and control the production of products.
- Total quality management (TQM): This applies quantitative methods as the basis for continuous improvement. TQM relies on facts, data and analysis to support product planning and performance reviews.
The advantages of applying quality assurance:
- improving the maturity of the organization.
- ensuring the effectiveness of the process being followed.
- facilitating to tailor the procedures for the user.
- Improving customers’ confidence.
- It leads to cost reductions stemming from the prevention of product defects.
- No barriers between workers and managers (QA cultivates collaboration rather than supervision)
