Introduction for History of QA
Quality Assurance (QA) has played a pivotal role in ensuring that products, systems, and services meet certain standards of quality throughout human history. While QA as a formal discipline emerged in the 20th century, the underlying principles of testing, evaluating, and improving quality have been part of human civilization for millennia. From the ancient craftsmanship of tools and structures to modern-day software testing, QA has evolved in response to the complexity of human activities and technological advancements.
The great emphasis on delivery of quality software has made software testing an inseparable procedure in the Software Development. Since the invention of computers in 1822 to the current era of systems, the terminology system faults have evolved into a vast subject of software testing. The history of QA dates back to the 19th century. It includes a huge glossary of software testing terminologies, procedures, standards, policies, approaches, frameworks, testing tools.
The history of QA concepts dates starts with the computer invention. The Babbage machines invented by Charles Babbage, an English inventor in 1822 were considered first among the mechanical computers. However, the term bug was first reported to be used by Thomas Edison in 1878 which was mostly associated with hardware, when he writes a letter to his associate in Edison papers-
‘It has been just so in all of my inventions. The first step is an intuition and comes with a burst, then difficulties arise this thing gives out and [it is] then that ugs as such little faults and difficulties are called show themselves and months of intense watching, study and labor are requisite before commercial success or failure is certainly reached.”
The World War II (1939 – 1945) led to greater advancements in computer technology. Electronic computers were prominently used to break the secret codes and crack secrets of war communication. In the same year, 1945 the term computer bug was first coined by Grace Murray Hopper in the history of QA. In 1951, Joseph Juran marked the importance of Quality of software in his book – Quality control handbook. The software testing terminology was clearly distinguished when Glenford J Myers published his book Art of Software testing in 1979. By today’s standards, errors refer to human mistakes, that lead to bugs or defects in the software, and cause the software failure. The ISO founded in 1946, has majorly contributed towards standardizing the procedures, artifacts, methods & techniques of software development & testing. The other contributors are IEEE, CMMI, six sigma which defines the standards of quality and defines framework for improvements to achieve the quality of software.
The software testing subject is to be treated with highest priority as it can avoid the setback in the economy by preventing the failures of software. The Ariane 5 flight 501 rocket – a project worth $8 billion dollar in 1996 failed due to a software defect. According to 2002, NIST (National Institute of Standards & Technology) reports the cost of software bugs to US economy is $59.5 billion annually. In 2003, the Northeastern and Midwestern United States and Ontario in Canada had second most widespread blackout due to a software defect in an alarm system.
Software testing field has created the job opportunities for test engineers & training staff, business opportunities for software testing training institutes & career colleges, vendors of testing tools, the scope of research for subject matter experts.
Conclusion
The history of QA is a testament to the continuous quest for improvement in human endeavor. From the early days of craftsmanship to the modern digital age, QA has evolved from informal inspections to complex, data-driven processes that span industries. Today, QA is more important than ever as technology advances rapidly, and customer expectations for quality continue to rise. As QA continues to evolve, its core mission remains the same: ensuring that products, systems, and services meet the highest standards of quality, reliability, and performance.

Software testing for faults has made quality software delivery possible in software development since the invention of computers in 1822 (19th century} to date and has advanced unto QA which includes software testing terminologies, procedures, standards, policies, approaches, frameworks, testing tools.
The history of QA concepts started with Babbage machines invented by Charles Babbage in 1822 and the term bug was first used by Thomas Edison in 1878 mostly associated with hardware, in Edison papers-
“Bugs” are little faults and difficulties showing up in his inventions until he finds solution to them through watching, study and labor, until success or failure is certainly reached.”
The World War II (1939 – 1945) led to greater advancements to break the secret codes and crack secrets of war communication which by 1945 the term computer bug was first coined by Grace Murray Hopper and by 1951, Quality control handbook was written by Joseph Juran. and Art of Software testing book written by in 1979 Glenford J Myers. ISO founded in 1946 and IEEE, CMMI, greatly improved the quality of software.
The software testing subject is high priority in the economy by preventing the failures of software as in the examples of The Ariane 5 flight 501 rocket and the cost to US economy due to a software defect in alarm system.
Software testing field has created the job opportunities for test engineers & training staff, business opportunities for software testing training institutes & career colleges, vendors of testing tools, the scope of research for subject matter experts.

History and evolution of software testing
THE INVENTION OF THE FIRST MECHANICAL COMPUTER – “THE BABBAGE MACHINE,” WHICH HAS HAPPENED IN 1822 BY AN ENGLISH INVENTOR CHARLES BABBAGE.
RIGHT SINCE THAT TIME, FROM THE 19TH CENTURY, THE HISTORY OF SYSTEM FAULTS AND ARRANGING SOFTWARE TESTING TO ELIMINATE THEM HAS BEGUN. THE TERM “BUG” IS BELIEVED TO BE USED FOR THE FIRST TIME AND THEN COINED BY THOMAS EDISON IN 1878. ALTHOUGH EDISON WORKED MOSTLY WITH HARDWARE, HE WROTE A LETTER TO HIS ASSOCIATE, IN WHICH HE COINED THE WORD “BUG”. THE ASSOCIATION WAS BRILLIANT, AND SOON IT HAS BECOME A WORLDWIDE TERM USED TO NAME FAULTS IN SOFTWARE
AFTER THE WORLD WAR II THE TERMS “COMPUTER BUG” AND “DEBUGGING” WERE OFFICIALLY COINED IN THE HISTORY OF SOFTWARE TESTING BY GRACE MURRAY HOPPER.
IN 1951, JOSEPH JURAN, WHO IS NOW CONSIDERED TO BE THE FATHER OF SOFTWARE TESTING, FOR THE FIRST TIME MARKED THE IMPORTANCE OF SOFTWARE QUALITY ASSURANCE IN HIS BOOK “QUALITY CONTROL HANDBOOK”. HE HAD ALSO DEFINED 3 PARTS OF QA MANAGEMENT: QUALITY PLANNING, CONTROL, AND IMPROVEMENT.
This article gives a brief history of QA automation. The quality of any software is so important and failure to give attention to quality comes with sad consequences as shown in this article. As a result, this has given rise to a lot of opportunities in in the field of QA automation.
