In one HR job I had, we went through a disruptive technology transition. Of course, pretty much any tech transition is disruptive. Even the best-laid plans don’t work perfectly.
Applicant flow had slowed as we moved from one HR platform to another and we paused job advertising as we made the switch. I had planned for this slowdown, but the change took an extra week due to miscommunication between our IT department and the software vendor. It wasn’t great, but there also isn’t much you can do in the heat of the situation.
