Save Money by Investing In Models; Failing Early is More affordable Than Failing Late

abstract Many stakeholders in systems development are unaware of the unknowns. Making and using virtual and physical models helps to validate assumptions, to calibrate the understanding, and to identify uncertainties and unknowns. A major risk is that some stakeholders think that they can afford to skip the laborous phase of trial, error, trouble shoot, and validation. It is an old wisdom that it is less costly to fail early than to fail late. We will use two cases from the semiconductor industry for illustration.
