Software Quality Tester – A Decent Software Guarantee

Quality assurance has always been the key to success when releasing a software product. The process helps identify potential risks and provides solutions that can prevent minor slip ups from derailing your project, ensuring positive outcomes for everyone involved. Believe it or not, NASA had to learn how important software quality assurance is the hard way. In fact, it cost them a spacecraft named the Climate Orbiter that originally was sent to Mars to study this particular planet back in 1998. Unfortunately, they lost it on September 23th, 1999 due to a wrong command from Earth which had been done by the engineering team who didn’t convert the measurements that they had inputted into the commands from English units (pound-seconds) into metric standard (Newton-seconds). Such a “silly” mistake was worth USD $125 million as the cost of building the spacecraft alone without any launching and operations cost added up yet.

The event had truly highlighted the importance of software quality testing, reminding us all that thorough tests are the fundamentals to avoiding potential losses from badly written code. Then what does it take to become a perfect “warrantor” for your business? Let’s explore this concept today and uncover what it takes to become aspiring software quality testers.
