While its difficult to separate the impact of card sorting from the impact of the other activities that comprised this project, in the year since its redesigned site launched, Eurostar’s online revenues grew from £110 million to £136 million (an increase of 24%, or £26 million!).

PS. I’m colour-blind and I find it quite difficult to pick out the embedded links on your site.

Like you say, the biggest challenge with any card sort is making sense of the results. Dendrograms are defacto favourites of course, but it seems that no one REALLY understands how this works. I’ve never got any decent results from them compared to the classic “eyeballing” of results (which yields different results depending on who does it and how much sleep they’ve had..)

Of course, I’m a bit biased.. as we just released an online card sort tool that doesn’t do dendrograms.. Of course, I’d like to think I could change your mind about the comment you made here:

>> …but I find it easier to have people play with index cards over learning how to use a tool just so your data collection life can be easier.

ps. On the subject of physical cards, we’ve done a whole lot of these both printed on index cards and handwritten on Post-It notes - no observable difference in our opinion.

For the title-conjuring, I give people blanks.

Do you find when the cards are printed versus handwritten that you get more, less, or no difference in people writing on the cards to change the items?

Much like people comment less on “finished looking” prototypes, I wonder if people would feel like they could change things if needed if the cards were printed.

I find that it is best to have the cards printed in a sans-serif font. But perhaps that’s just me.
