Re-evaluating & comparing two designs
After the initial DFX analysis of a certain MBOM, different conclusions will be made about the design and likely resulting in a proposed re-design of the product. It is thus a logical step to compare the “DFA score” for the original MBOM with the new re-designed one.
Re-evaluating new design
As per methodology
COMPARING DFA SCORES
When comparing two designs it is noticeably that an improved design might have a lower DFA score than the original design. This is because eliminating a part will reduce the total score, making it difficult to compare designs using the DFA-score (Aggregated score) itself.
When comparing two designs, you can:
- Use the Agg Score (%)
- Use the theoretical DFA-time
- Each DFX aspect generates a time based on a theoretical optimal assembly. Thus, comparing two designs where the new design has a lower DFA score it will also have a lower DFA time since it conatins less parts
- Each DFX aspect generates a time based on a theoretical optimal assembly. Thus, comparing two designs where the new design has a lower DFA score it will also have a lower DFA time since it conatins less parts
- Compare the total number of parts.
- Less parts will be a simpler (better) design
- Less parts will be a simpler (better) design
