one–way road issue – can SPC help that?
I read some latest blogs today and quite a few of them were about SPC and its examples around us.
As I was going back home, in my home city in PL, we have got a one-way road that starts at my neighbourhood and throughout a year everyone goes as they suppose. However, today I noticed a car going upstream! After one minute, there was another one (they didn't see the signs, but that's normal, fair enough then).
Probably, all it means that there are more cars around, not from my city. This is of course because of Christmas... which is a ... special cause then! :D So if we made a SPC chart for that (and obtain proper results and data, not just my assumptions!), we could get some good results and maybe my Council could take some actions i.e. re-think positions of signs etc...
