Method | Advantages | Disadvantages |
| Easy to quantify as inputs known | Only at specific time, small error in P |
| Solid input for some products, future extrapolation has low error | Demands future extrapolation and resultant errors for all inputs |
| Provides total value with low error | Demands future extrapolation, difficult quantification of secondary benefits |
| Easy calculated precise value for single company | Only useful for single company |
| ND available and generalized cost assumptions tolerable | Uses P and associated errors, assumes all firms have similar costs and values, demands future extrapolation |
| Captures value throughout time | P errors, Firm value/costs errors, demands future extrapolation |
| Captures total value with solid foundation for direct costs | P errors, Firm value/costs errors, Demands future extrapolation, quantification of secondary benefits difficult |
| Easy to calculate | Only true if mass-scale distributed manufacturing established at single time, misses all secondary benefits |
| Relatively easy to calculate | Only valid if mass-scale distributed manufacturing established, demands future extrapolation and resultant errors |
| Approaching the optimal deployment and thus value of OSH | Only valid if mass-scale distributed manufacturing established, demands future extrapolation, estimation of secondary benefits and resultant errors |
