Week 14: Exercise 2 (Step-Method)
See Exhibit 2 for a diagram of the flow of costs and the sequence in which costs are allocated.
Note: The sequence in which the departments are raked is important. This is because, with the Step-
Method, the costs of a support department are never allocated to a support department above in the
sequence.
