Performance metrics tables - the meat behind the percentage increases and decreases
Over the last few days, our pal Rusty (and others) have questioned the worth of the Ron Huberman's President's Report, calling it a "self-written job review," "self-generated PR" and "spin." Rusty says, ". . . let's get the numbers parsed and crunched in a way that comes up with conclusions that have some real meaning beyond an annual self-review."
Fair enough. So have at it Rusty. The numbers come from the monthly Performance Metrics tables that the CTA has published since 2004. However, when Huberman came on board, he didn't like the format and wanted to make sure they were measuring the right things, so he changed results they were measuring and released a dashboard report, where you could see at a glance whether the CTA was hitting its target (Green), coming within 10% of the target (Yellow), or missing the target by 10% or more (Red). And the target/goal is clearly defined.
In retrospect, I realize I should have posted this yesterday. Hindsight is 20-20.The most recent table (pdf) on the site shows the latest November figures, while the board report has December numbers. But they are chock-full of informational nuggets, such as:
- In November 2008, there were 66 rail delays of 10 miutes or more.
- In January 2008, there were 132 such rail delays.
- The target is 78 such delays or fewer.
Below is my own edited, mash-up of the table to fit into this tight space.
But you should go ahead and download the PDF to get your head spinning from all those figures. A quick glance shows that the CTA never met its goal in 2008 of having less than "2% of weekday bus intervals (time between two buses at a bus stop) that are 60 seconds or less divided by the total number weekday bus intervals traveled during the month."
And Rusty, let us know what you find when you are done parsing and crunching.
