Okay, let’s tackle this. So Darrell Simmons has a mix of technical and management skills. Supplier Quality Engineering and Manufacturing Engineering are in demand, but not as high-paying as Lean Six Sigma or Project Management. He has experience with production part approval process, which is a specialized skill. Considering his skills and experience, I’d estimate his rate to be around $125 per hour, which is in line with national averages for professionals with similar skills in the Detroit area.
