Reliability theory is a general theory of systems failure developed by mathematicians:
Reliability theory was historically developed to describe failure and aging of complex electronic (military) equipment, but the theory itself is a very general theory based on probability theory and systems approach.
Why you need to counterbalance:

To avoid fatigue effects – subjects get tired and performance on later items suffers
To avoid practice effects – subjects learn how to do the task and performance on later items improves
