Methodology

1. Decide whether the DFA is focusing on manual or automatic assembly, different aspect templates can be used in AVIX
   
   
2. Import MBOM  (if only a EBOM is available a MBOM can be built in AVIX)
1. The parts in AVIX can carry/contain pictures to be used in the DFA
2. 3D models can be used in parallel with AVIX, e.g. Adobe Acrobat Reader

3. Decide the base object (set as N/A these will not be evaluated). E.g. a plastic casing containing other parts. This will typically be a sub-assembly containing other parts. The plastic casing is the base object.
   
   
4. Follow the MBOM
1. If a work instruction/decided work sequence is available, follow it
2. If not, follow the MBOM starting with the sub-assemblies
3. Make the DFA evaluation according to the DFA aspects in AVIX
4. Red and yellow (low score) à Make a note in AVIX, assign responsible (do not fix the problem during the initial session)
5. Try making red parts yellow and yellow parts green by design changes
6. Make a copy/paste of the MBOM, then make changes/improvements and a new MBOM (this assures that we have a present/future state to compare in terms of DFA-score
5. Make a new DFA analysis on the copy/pasted MBOM
1. Compare if it became better/worse
2. Remember to compare not only total DFA-score, but also time. If a part is eliminated the total DFA score can go down making the result looking worse. But comparing the theoretical standard times will show a total assembly time reduction.
3. Remember also to compare the relationship: Total DFA-score/Theoretical total score when comparing present vs. future state of the design.
