Hi,

I knew it was intended to implement the option to create BWS Case 3 designs in any future Ngene version. Is there any update on the topic?
So far, for surveys with best-worst choice tasks we use designs optimized for best choices.

Thank you!
Andrew

HI Andrew,

Best-worse case 3 is scheduled for implementation in Ngene 2.0, together with several other major features. We do not have a firm timeline yet, but we aim for release next year.

Dear Michiel,
thank you very much for the fast response.

I'd like to ask a follow up-question: We are about to create a design for a BWS case 3 using an efficient design for best-choices. There is 1 out of 4 attributes which levels will probably have the main attention of the participants. We want to use an overlap design for this specific attribute to force trade-offs between the remaining attributes. I guess we can use new the Ngene version 1.2 and do not need the special build 1.12b with canditate sets to control the amount of overlaps.
Do you think there could be any problem/disturbance using overlaps for a BWS case 3 design?

Kind regards,
Andrew

Hi Andrew,

Yes you can use the new Ngene 1.3 and read in an external candidate set.
I do not see any issues in using overlap between attributes for BWS case 3 since you will always be trading off on attributes that are non-overlapping.
