Also, our pathology department has a new managed equipment service and we're going live with new equipment on Sunday 6th...There are so many problems with this.
Why not do it on the Saturday like everyone suggested? So you have the entire Sunday to go "Hey shit, this isn't working out like we planned. We're backed up."
"It's a good job we did this on a day when we only have 4000 samples coming through the lab the next day, rather than on a Sunday when the next day there's 16000+ coming through."
I should also note that NONE of the service users have yet been informed that basically there's going to be huge disruption to the diagnostic service that week.
