Task is the characteristic of a job that refers to how predictable job duties are from one day to the next.

variability

Explanation:

When a worker is performing a task, he or she might come across a situation that is not expected or a situation not experienced before. Task variability enables the prediction of certain tasks, especially where those task are standardized and repetition of such reduces task variability.

Also, any exceptions experienced when carrying out a duty either in a new situation or at any stage in the value creation process, such would eventually make task variability high. In other words, take variability refers to the numbers of exceptions, a worker experienced when carrying out a duty.
