"You can not define being exactly on time"

This quote by W. Edwards Deming talks to the concept that there is no one-size-fits-all meaning of punctuality. Being on time is a subjective concept that can vary depending on the scenario and the expectations of those involved. For instance, showing up five minutes early to a conference might be thought about on time in one context, while arriving five minutes late might be thought about on time in another. It is important to recognize that being on time is not a universal idea, which it can be interpreted in a different way depending upon the context. Furthermore, it is important to be aware of the expectations of those involved in order to ensure that one is fulfilling the definition of punctuality. Ultimately, this quote functions as a pointer that being on time is a subjective concept and that it is necessary to be familiar with the expectations of those involved.
