Saving Money Through Substitution: A Plan-Based Approach
How much money can be saved by using alternative materials for hardware structural parts?
Calculate based on a plan: selection of alternatives (feasibility), performance verification (testing), cost comparison (price difference analysis), and risk control (safeguards).
Industry experts point out that savings should be evaluated according to a specific plan—selecting the alternative (feasibility), verifying performance (testing), comparing costs (analyzing the price gap), and controlling risks (establishing safeguards)—to ensure genuine, rather than illusory, savings.
Plan-Based Calculation
- Alternative Selection: Choose the substitute/plan first;
- Performance Verification: Mandatory performance testing;
- Cost Comparison: Detailed cost analysis;
- Risk Control: Risk mitigation and safeguards;
- Plan-Based Calculation: Calculate based on the plan to ensure real savings.
Key Evaluation Points
First, select the alternative carefully.
Choose the substitute/plan first to prevent haphazard swapping.
Second, mandatory performance verification.
Test performance to prevent quality degradation.
Third, detailed cost analysis.
Compare costs meticulously to avoid illusory savings.
Fourth, risk mitigation.
Implement safeguards to prevent failures.
Pitfalls to Avoid
First, “focusing only on price differences.”
Performance drops (risk); testing is mandatory.
Second, “cutting materials and functions.”
Customer loss (financial damage); risk control is essential.
Third, “swapping without verification.”
Incidents/hazards occur; follow the plan-based approach instead.
Trends and Reminders
The shift toward “validated substitution”: a trend combining validated replacement (standardization) with the application of new materials (innovation).
For purchasers, the recommended approach is to “calculate based on the solution, verify performance, and ensure risk coverage.”
This ensures tangible cost savings from substitution without compromising quality.
