Key Facts & Information
|Overview||Software quality assurance engineers and testers oversee the quality of a piece of software's development over its entire life cycle. Their goal is to see to it that the final product meets the customer's requirements and expectations in both performance and value. During the software life cycle, they verify (officially state) that it is possible for the software to accomplish certain tasks. They detect problems that exist in the process of developing the software, or in the product itself. They try and make things not work (try to "break" the software) by creating errors or combinations of errors that a user might make. For example, if a user enters a period or a pound sign for a password, will that break the software? They seek to anticipate potential issues with the software before they become visible. At the end of the life cycle, they reflect upon how problems or bugs arose, and figure out ways to make the software development process better in the future.|
|Key Requirements||Detail-oriented, thorough, persistent, with excellent communications skills and a love for puzzles and figuring out how to break software|
|Minimum Degree||Bachelor's degree|
|Subjects to Study in High School||Algebra, geometry, algebra II, pre-calculus, English; if available, computer science|
|Projected Job Growth (2012-2022)||More Slowly than Average (3% to 6%) In Demand!|

Training, Other Qualifications
Training requirements vary depending on the job, but many employers prefer applicants who have a bachelor's degree in computer science, or a similar degree. Relevant work experience is also very important.
Employers usually look for people who have broad knowledge and experience related to computer software development, strong problem-solving and analytical skills, and the ability to think logically. In addition, because they often deal with a number of tasks simultaneously, the ability to concentrate and pay close attention to detail is important. Although these workers sometimes work independently, they frequently work in teams on large projects. Therefore, they must have good interpersonal skills and be able to communicate effectively with computer personnel, users, and other staff who may have no technical background.
Nature of the Work
Software quality assurance engineers and testers have an eye for detail and are committed to improving the performance of the products a company sells. They ensure that the software packages being sold meet or exceed the customer's expectations in performance and value. The biggest software companies spend millions of dollars of their budget on hiring quality software assurance engineers to head their quality assurance departments. This money is well spent, because the software quality assurance engineer will make sure that the product is top quality before it is marketed and sold.
A software quality assurance engineer is involved in the entire software development process to ensure the quality of the final product. This can include processes such as requirements gathering and documentation, source code control, code review, change management, configuration management, release management and the actual testing of the software. Software quality assurance is often confused with software testing, but should not be. Testing is a big part of software quality assurance, but it is not, by any means, the only part of it.
Software quality assurance engineers must be familiar with the entire software development life cycle in order to be effective. They may start out as software engineers or as testing engineers. They should have strong communication skills, be good at documenting their work, and must be able to work well with different groups. They often become the middle person between the developers and the customers, so they need to be able to understand, and convey, both viewpoints.
In addition to running tests, software quality assurance engineers diagnose problems, recommend solutions, and determine whether program requirements have been met.
Software quality assurance engineers and testers work in offices or laboratories in comfortable surroundings. They usually work about 40 hours a week—about the same as many other professional or office workers. Evening or weekend work may be necessary, however, to meet deadlines or solve specific problems.
Like other workers who spend long periods typing on a computer, software quality assurance engineers and testers are susceptible to eyestrain, back discomfort, and hand and wrist problems such as carpal tunnel syndrome or cumulative trauma disorder.
