Jobs are classified into an existing grade/class/grade structure or hierarchy
Each class has a label description that captured sufficient work details while being general enough to allow slotting job descriptions onto the appropriate class

Need a benchmark job for each class
Question: How many job classes do we need? This is “ART”
Each class is dissimilar to other classes
Jobs in each class are similar to one another
