I found this very interesting, and it could be useful for collecting data.
This is an implementation of the NASA Task Load Index, implemented via HTML/js. https://www.keithv.com/software/nasatlx/
There are two phases in the process.
The link gives a web-based interface to set up an AHP problem, and evaluate in a group. A very useful aspect of this implementation is the user feedback on the Consistency Ratio (CR). And most importantly, the advice on which user inputs are not consistent. I think this helps the user re-evaluate and think about the input they put into the pair-wise comparisons, resulting in better and more accurate weights.
This is a very versatile decision support tool.
