I keep playing around with this in my head and I can’t come to anything but the conclusion that the unit of analysis for a sequence in interaction design is always dependent on the interaction and that dependency is because something is inherently important about each artifact and their functions differ. Or maybe it’s based on function? Can two artifacts that do the same thing have the same unit of measure in a sequence analysis? Or is it based on the sequence chosen that the unit of analysis? Would it be better to set the units of measure before even considering an artifact or would that miss the point?

by the unit of analysis, do you mean the column headers of the chart? I think one way to do this is that: we create a set of common aspects to look at in sequence analysis, but for each particular interaction, we might need to modify, add or remove, some aspects to fit into specific goal. However, the overall goal of sequence analysis is still, as Jeff said in his blog: “gain insight into the objective basis of a subjective phenomenon”.
Well, don’t really know what I’m talking about here…
