I have a DCM design where the attributes only vary for only product. We re varying 4 attributes. However, there are a few products shown.
There are two ways I see of moving forward:
1. Not including product as an attribute, and using a traditional none option.
- This will prevent prohibitions, but does not get a utility for the product we are varying attributes for
2. Including product as an attribute
- This will require prohibitions, and may hurt the strength of the design
It would be awesome to get your thoughts on which option would be better for conjoint design. I am primarily concerned with the utilization of the product that is varying, so I think approach #1 is better. Happy to get your perspective on the pros/cons of each option.
