Hi there. We’ve had them for a few years now and we find them excellent. What we did was segment our employee population with all the information we had not just what was on our HRIS, but also what we knew about how people travelled to work, what their family circumstances were like etc – it worked out as 8 separate personas. We then found employees that matched those personas exactly and interviewed them – aiming for 4 or 5 interviews per persona, and that gave each persona depth. We’ve used them as part of the thinking for all our employee experience work, policies and procedures. It’s good to do.
