Software-based engineering process that includes the use of modeling in multiple dimensions and in software simulated “normal operating conditions” in order to discover weaknesses, design improvement opportunities, and general refinement before physically building a tangible prototype.
Comments: Whatever the undertaking it generally pays great dividends to invest time and effort very heavily into the “front-end” of a product rather than try to “work the bugs out” after it has gone to manufacturing. Once again with “Speed to Market” concerns a balance must be struck so as to not lose out to faster competitors.
