A 'good' or even 'acceptable' productivity rate is incredibly subjective. However, experts suggest implementing a '70% rule' to help improve productivity. If a worker continuously performs at maximum capacity, he or she runs the risk of burning out. The 70% rule suggests working productively most of the time but with less intensity. This allows the employee some mental reserve to respond to any short-term urgent demands that may arise. Implementing the 70% rule involves taking mini-breaks during the workday, reserving unscheduled work time, and taking periodic vacations.
