2. Elimination of Uncertainty

An activity intended to eliminate technical uncertainty concerning:

  • Capability
  • – Optimal methodology
  • – Appropriate design
  • – Process or product improvement

Has your company demonstrated that it tried to learn something new about the product or process being changed in order to improve it and has it demonstrated that the product or process could not be improved without going through this discovery process?

3. Process of Experimentation

Implementation of a systemic approach to identify and evaluate different alternatives to achieve a desired result by:

  • Trying different technologies
  • Several iterations
  • Modeling and simulation

Has your company demonstrated that it went through a process of elimination, trial and error, or other evaluation of alternatives in order to arrive at the new or improved product or process?

  • – Engineering
  • – Physics
  • – Chemistry
