Answer:
The stage of the design process where the industrial engineer becomes involved is the define or design definition stage
Step-by-step explanation:
The process for Design For Six Sigma, (DFSS), and also in the process for solving design problems there are similar process stages such as the Define, Measure, Analyze, Design, Verify, DMADV, stages in six sigma and Define, Gather, Generate, Analyze, Test in the design for problem solving
The point at which the industrial engineer becomes involved is the definition stage or point where the designer's abstract idea is developed and clearly defined by following a series of step wise processes which requires project management, engineering economics, industrial quality control and engineering management skills.
