Military and aerospace system developers have one overarching mission: to bring their products to market in the most efficient manner possible. As much as the engineers might want to build systems themselves from the ground up, the exigencies of the marketplace dictate otherwise. Two measures of maturity technology readiness level (TRL) and manufacturing readiness level (MRL) can be used to advantage by the systems developer to reduce its time to market with new products. The use of these metrics can reduce non-recurring engineering (NRE) costs to the system developer to improve the profitability of the delivered system. This white paper examines how a system developer can leverage the concepts of TRL and MRL to gain market advantage at the least overhead cost.
