In user experience design (UX) research, we think a lot about mental models — how a user believes a process works vs. the system model of how it was actually designed; and framing — the context in which an interaction is interpreted. In essence, your satisfaction within an experience can depend a lot on your initial expectations.
For new employees, the expectation we need to set is that while the initial learning curve is steep, the on-boarding process actually never ends nor does it move in a predictably straight line.
The UX explanation for why you hate your new job after three months
Companies should approach new hires with the same vigorous approach they have, or wish to have, with product development. People aren’t software but understanding each new hire, and their needs and expectations, to the extent that you know the users of you product would go along way to producing happy talent. And happy talent has a whole slew of side benefits. Unfortunately, to my knowledge this is seldom done in Taiwanese or Chinese companies.
