The cause is rarely the technology. It is people, inside the business and among its customers, moving through change at different speeds.
It is not whole teams that struggle. It is certain individuals: some race ahead without understanding the detail, others dig in. That imbalance is what slows the work down.
The leaders overseeing the rollout are often not equipped to handle it. Their own role is changing too, as they manage work that spans both people and AI.
Investment in AI often arrives alongside change to the workforce. Add a potential workforce restructure into the mix, and that unease deepens. People start asking what their role becomes and what skills they will need.
Fear rarely looks like fear. It shows up as behaviour: disengagement, reluctance to ask questions, time off sick. After months of change, fatigue sets in too.
If the people who remain are not consistently engaged, the business does not get the return it expected from its technology investment.
