==Design For Manufacturing and Assembly == ===Step 1. Estimate the Manufacturing Costs === Fixed Costs vs. Variable Costs The Bill of Materials Estimating the Costs of Standard Components Estimating the Costs of Custom Components Estimating the Cost of Assembly Estimating the Overhead Costs ===Step 2. Reduce the Cost of Components === Understand the Process Constraints and Cost Drivers Redesign Components to Eliminate Processing Steps Choose the Appropriate Economic Scale for the Part Process Standardize Components and Processes Adhere to ''Black Box'' Component Procurement ===Step 3. Reduce the Costs of Assembly === Keeping Score Integrate Parts Maximize Ease of Assembly Consider Customer Assembly ===Step 4. Reduce the Costs of Supporting Production === Minimize System Complexity Error Proofing ===Step 5. Consider the Impact of DFM Decisions on Other Factors === ... On Development Time ... On Development Cost ... On Product Quality ... On External Factors ==Robust Design== ===Step 1. Identify Control Factors, Noise Factors, and Performance Metrics === ===Step 2. Formulate an Objective Function === ===Step 3. Develop the Experimental Plan === Experimental Design Testing Noise Factors ===Step 4. Run the Experiment === ===Step 5. Conduct the Analysis === Compute the Objective Function Computing Factor Effects by Analysis of Means ===Step 6. Select and Confirm Factor Setpoints === ===Step 7.
