Does every software project need testers?
It depends on the size and context of the project, the risks, the development methodology, the skill and experience of the developers. If the project is a short-term, small, low risk project, with highly experienced programmers utilizing thorough unit testing or test-first development, then test engineers may not be required for the project to succeed. For non-trivial-size projects or projects with non-trivial risks, a testing staff is usually necessary. The use of personnel with specialized skills enhances an organization’s ability to be successful in large, complex, or difficult tasks. It allows for both a) deeper and stronger skills and b) the contribution of differing perspectives.
