...Engineering has not been schooled or trained to
meticulously keep proof of the processes, product, and
verification real-time. The engineers have focused on the
development of the product, not the delivery. In addition,
program durations can be from 10 to 15 years resulting in
the software engineers moving on by the time of system
delivery. This means that most management and engineers
have never been on a project from "cradle-to-grave."
