Matt, Mudlark’s CTO, always make pictures – which usually help technical-dullard me far more than some of the more elaborate discussions.  Here’s his sketch of the data flow for the BCD project.

And the data has begun to flow – into our developer Chris Thrope’s grateful clutches. We’ve had some very interesting chats about what we can know about each call and what we want to know.How precisely should we pinpoint a call? Should we (can we?) focus on the location where the resident lives or where they say the issue is ? These may or may not be the same thing.

We reckon that as much as showing patterns of incidents and issues, the BCD may well plot where the most active complainers are. What cliches and stereotypes we reveal or destroy remains to be seen.
