39. • Techniques such as automated testing,
    continuous integration and continuous
    deployment allow software to be
    developed to a high standard and easily
    packaged and deployed to test
    environments, resulting in the ability to
    rapidly, reliably and repeatedly push out
    enhancements and bug fixes to
    customers at low risk and with minimal
    manual overhead.
