The U.S. Department of Labor predicts that employment for quality control inspectors in the software development industry will grow much faster than the average for all careers through 2022. Before, software companies were able to make big profits by being the first to introduce a specific kind of product, such as a word processor or presentation kit, to the marketplace. Now, with so many versions of similar software on the market, competition is forcing firms to focus their energies on customer service. Many companies, therefore, aim to perfect their software applications before they hit the shelves. Searching for every small program glitch in this way requires the effort of many quality assurance testers. Additionally, the sheer number of software applications that are being created for computers, smartphones, and other digital devices is creating strong demand for testers who can manually check software programs or design and oversee automated programs that can handle this important task.
