From a WFM perspective, schedule your best agents for the go-live weekend.
Don’t let your most experienced agents take that weekend off. If something goes wrong, you need agents who can adapt to a new system under pressure. Schedule your newest agents for the following Monday when the system is stable.
We forgot to test the emergency flow during our go-live weekend.
Everything worked perfectly from Saturday through Sunday. Then at 6 PM Sunday, the after-hours emergency flow should have activated but didn’t because the schedule group timezone was wrong. We had 2 hours of missed emergency calls before an engineer noticed. Test EVERY schedule transition.
