How do you approach manufacturing cost optimization for a new product introduction?

Manufacturing cost optimization approach: DFM/DFA analysis during design (reduce part count, simplify assembly, standardize fasteners), Make vs buy analysis (core competency, volume, capital requirements), Process selection optimization (compare casting vs forging vs machining based on volume and geometry), Material cost optimization (specification review, alternative materials, near-net-shape), Tolerance optimization (cost-tolerance studies, reduce tight tolerances where non-critical), Cycle time reduction (lean principles, automation analysis, setup time reduction), Supply chain optimization (supplier consolidation, regional sourcing, logistics), Quality cost analysis (prevention vs appraisal vs failure costs), Capital efficiency (equipment utilization, flexibility for volume changes), and Total cost of ownership modeling. Target 20-40% cost reduction through systematic analysis. Use cross-functional team including design, manufacturing, supply chain, and quality.
