What does under-plan mean?
When deadlines are distant, managers can shift people’s attention away from the deadline and toward the final outcomes of everyday tasks. Reminding employees of the final payoffs of different tasks is an effective way to do this. And there are times when longer deadlines are more effective than short deadlines, such as when individuals have a natural tendency to under-plan, in saving for college or planning for retirement, for example. Though some people will procrastinate or abandon the task, those that do take it on will achieve the goals because they assume that they need to put more effort into the task than what is typically required. In this case, the deadline pressure serves to balance against under-planning.
I don't understand under-plan meaning and example in this context. Does it mean "stick to plan"?
