My recent post on PROC GKPI and dashboards was very popular (judging by the number of hits), but I got a number of email comments suggesting I should talk more about the content rather the presentation, i.e. what to measure.
It's certainly a subject I'd like to return to, but in the meantime you could do a lot worse than to visit the blog of Wayne Eckerson (director of research and services for The Data Warehouse Institute - TDWI). In particular, check-out his recent series named Crossing The Chasm.
